Analytical Steady-State Model for the Free Radical Solution Copolymerization of Acrylonitrile and Vinyl Acetate and Their Charge-Transfer Complex in a Continuous Stirred Tank Reactor

In this study, a mathematical model of the copolymerization of AN-VA in a continuous stirred tank reactor (CSTR) was developed considering charge-transfer complexes (CTCs). CTC formation between acrylonitrile (AN) and vinyl acetate (VA) was demonstrated using UV-VIS spectrophotometry and molecular orbital theory. The rate constants and equilibrium constants of the complexes were calculated from a model of the simultaneous participation of complexes and free monomers and the molar ratio method. Furthermore, the participation of CTCs in propagation was included because of their high reactivity. All the simultaneous equations defined to analyze the reactor parameters were analytically solved, and the results of the model were in terms of operative variables such as monomer conversion, average molecular weight, and the mole fraction of monomer 2 (i.e., VA) in the polymer formed. The results of the predictions of the developed model were compared with the experimental data for validation. This prediction was also compared with the reactor model solution without considering the CTC, which showed deviations that were more significant than those of the CTC model. These results represent a quantitative way to analyze the order of magnitude of the impact of the formation of the complexes in the analyzed polymerization system.

Structure and ferroelectric properties of P(VDF-TrFE) films prepared under different conditions — Effect of filtration of the copolymer solution

Vinylidene fluoride-trifluoroethylene copolymer films of molar ratio 70/30 with thickness of about 1 [Formula: see text]m have been deposited from solution in ethyl methyl ketone to a glass substrate with an aluminum electrode by spin coating. The solution has been filtrated through a PTFE membrane filter with pore size 0.2 [Formula: see text]m directly before spin coating or it has been used as is (unfiltrated). After deposition of a top electrode, the samples have been polarized by hysteresis loops with an electric field amplitude of about 100 V/[Formula: see text]m. In samples, annealed at temperature 145[Formula: see text]C for 3 h, a high remanent polarization of about 7.5 [Formula: see text]C/cm2has been achieved, without significant differences between samples fabricated of filtrated or unfiltrated solution. Spherulitic lamella are growing in films fabricated of filtrated solution when they are heated above the melting temperature to 159[Formula: see text]C for 3 min before the further annealing process at 145[Formula: see text]C. These films show substantially lower remanent polarization below 4 [Formula: see text]C/cm2. Pyroelectric images recorded with a pyroelectric laser scanning microscope show that the spherulites have very small pyroelectric activity, i.e., the spherulites consist of flat-on lamella. In contrast, no spherulitic lamella are growing in films fabricated of unfiltrated solution heated above the melting temperature, melted and annealed under the same conditions. An explanation for this observation is that filtrating changes the structure of the copolymer in solution from polymer coil to rod. Copolymer rods deposited on a substrate will crystallize in flat-on lamella when heated above the melting temperature, in contrast to copolymer coils which crystallize in edge-on lamella.

A wide range of poly(glycolic acid)‐based di‐ and tri‐block polyesters by a single organocatalyst: Synthesis and characterization

AbstractThe ring‐opening polymerization (ROP) of glycolide (GA), the copolymerization of GA with ε‐caprolactone (ε‐CL), and the terpolymerization of GA with ε‐CL and lactide (LA) were studied over the cheap non‐toxic metal‐free organocatalyst tetrabutylammonium 2‐(carbamyl)benzoate (TBACB). The catalyst with comparable catalytic activity to the comonomers afforded a series of well‐defined PGA‐based block polymers with ε‐CL, LA monomers at high yields by varying feeding methods under bulk and solution conditions. The poly(ɛ‐caprolactone‐b‐glycolic acid)s (PCGAs) and poly(ε‐caprolactone‐b‐lactide‐b‐glycolide) (PCLGAs) with controllable chain segment composition were obtained by “one‐pot” solution copolymerization in mixtures, or semi‐batch copolymerization. Due to the high thermal stability of TBACB, the PCGA and PCLGA with high molecular weight (Mn = 6.9 and 10.0 kg mol−1) could also be obtained by bulk polymerization at 120 °C by sequential addition of ε‐CL, (LA), and GA in a short time (<2.5 h). Compared to the polymers with similar compositions by different methods, the bulk polymerization showed more effective and higher molecular weight. The microstructure characterized by NMR showed highly ordered block polymers with defined chain segments. Two melting transitions (Tm) of PCGA suggested exclusively associated with PCL and PGA segmental chain in the product.

Synthesis of a novel magnetically recyclable starch-based adsorbent for efficient adsorption of crystal violet dye

A novel magnetic starch-based adsorbent (MSBA) was synthesized from the copolymer solution of starch-grafted acrylic acid treated by an alkali homogeneous phase as the precursor and Fe3O4@SiO2 particles as raw materials. The feasibility of dye wastewater treatment was studied using crystal violet (CV) cationic dye as the model dye. The research results have indicated when the optimum condition kept the temperature of 308 K, CV concentration of 10 mg·L-1, pH of 9.0, the adsorbent dosage of 0.10 g, and the adsorption time of 50 min, 90.31% of the CV can be removed by the MSBA. In terms of the Langmuir isotherm model, the maximum adsorption capacity for CV was 49.10 mg·g−1. The magnetic saturation intensities of MSBA were 14.80 emu·g−1. The kinetics results showed that the adsorption process conformed to the first-order model and the rate-controlling step was determined by multiple stages. In addition, the adsorption isotherms displayed that CV adsorption was well fitted to the Langmuir model, and thermodynamic parameters depicted the spontaneous endothermic process. The adsorption mechanism of CV involved electrostatic interaction and hydrogen bonding. The adsorbents can be regenerated in ethanol solution and the removal efficiency remained at 83.04% even after five adsorption-desorption cycles. MSBA can be recovered with a magnet and only experience a 7.6% loss of adsorbent with each reuse cycle. These results suggest MSBA is a promising candidate adsorbent for dye wastewater treatment because of its excellent properties, including high adsorption efficiency, simple magnetic separation and reusability.

Structurally well-defined functionalized polyolefins and graft copolymers thereof as bitumen modifiers

Here we demonstrate the application of hydroxyl-functionalized propylene-based copolymers, poly(propylene-co-1-hexene-co-10-undecen-1-ol) (FPP) and poly(styrene-co-maleic anhydride) (SMA) graft copolymers derived thereof, poly(propylene-co-1-hexene-graft-styrene-co-maleic anhydride) (FPP-g-SMA) as bitumen modifiers. The FPP samples were synthesized via solution copolymerization, while FPP-g-SMA products were obtained via transesterification of FPP with SMA either in solution or by a melt-grafting process. FPP-g-SMA modifiers prepared in solution, having a SMA content of around 30 wt%, performed very well as compatibilizer for bitumen, generating a polymer-modified compositions with a uniform morphology and improved nanomechanical properties, storage stability, rheological properties and high-temperature performance as compared to neat bitumen samples.

Facile fabrication of superhydrophobic surfaces via spraying with silicone-urea copolymers

The microphase separation method is recognized as one of the most promising approaches to fabricate superhydrophobic surfaces (SHS), but it is still subjected to confined polymer materials, expensive instruments, and complicated techniques. Here we innovatively proposed a solvent evaporation-induced self-assembly method to produce SHS with facile prepared, environmentally friendly, ultrafast ambient temperature curable properties. In this study, a new category of silicone-urea copolymers was synthesized via step-growth polymerization of polydimethylsiloxane (PDMS) and different diisocyanates. The SHS induced by the microphase separation and solvent evaporation was then fabricated by spraying these copolymer solutions onto various substrates. It was discovered that the surface superhydrophobicity and morphology can be readily tuned by varying the spraying concentrations, diisocyantes, solvents, spraying heights, and molecular weight of PDMS. And those synthesized copolymers were assembled into micrometer-size fibers or spheres consisting of hierarchical microstructure using tetrahydrofuran as spraying solvent and 10–15 cm spraying height, and the contact angles of surfaces reached 119° and 153°, respectively. To further explore the possible formation mechanism of the SHS, small-angle scattering, and X-ray photoelectron spectroscopy were carried out to investigate the effects of the microphase separation and solvent evaporation. With the induced microscopic roughness caused by the copolymers, these prepared super-anti-wetting surfaces have been demonstrated for potential utilization in the field of waterproofing, self-cleaning, and antifouling aspects. This work provides an effective way for the potential large-scale preparation of superhydrophobic surfaces with environmentally friendly materials and straightforward techniques.

Hydrogels Based on Chitosan and Sodium Alginate with Shape Memory Effect

Hydrogels based on chitosan derivatives, sodium alginate with acrylamide and acrylic acid were obtained by free radical solution copolymerization method in the presence of ammonium persulfate as initiator and urotropin and N,N methylene bisacrylamide as crosslinking agents. The formation of hydrogels was proved by extraction and IR spectroscopy. It is shown that hydrogels are able to fix the temporary form in iron (III) chloride solutions and reclaim it in solutions of ascorbic acid in less than 2 hours. Hydrogels based on sodium alginate have the best physical-mechanical characteristics compared with chitosan-based - the strength reaches 0.7 MPa and 0.11 MPa, the elasticity modulus is 1.02 MPa and 0.17 MPa at 65% deformation, correspondingly.

Nanostructure Scaling in Semi‐Dilute Triblock Copolymer Gels

AbstractThere is a considerable body of work that describes the scaling of diblock copolymer micelle dimensions in dilute and semi‐dilute solution based upon block degrees of polymerization and copolymer concentration. However, there is a lack of analogous information for semi‐dilute ABA triblock copolymer gels, which consist of ABA triblock copolymer dissolved in midblock‐selective (B‐selective) solvent. The present study uses small angle X‐ray scattering to extract micelle dimensions for numerous triblock copolymer gels that vary in copolymer identity (and hence block lengths) and copolymer concentration, as well as gels that contain various ratios of two unique triblock copolymers. Analysis of micelle structural data subsequently translates to universal scaling expressions for the micelle core radius – rA ≈ NA0.53NB−0.14ϕABA0.16 where NA and NB are the endblock and midblock degrees of polymerization, respectively, and ϕABA is the volume fraction of triblock copolymer in the gel – and for the intermicelle spacing – lAA ≈ NA0.09NB0.29ϕABA−0.35. Each scaling expression describes the full collection of experimental data very well. Additionally, these scaling expressions are partially in line with expectations from semi‐dilute diblock copolymer solution theory.

COPOLYMERIZATION OF UNSATURATED OLIGOESTERS MODIFIED WITH NITROGEN-CONTAINING COMPOUNDS WITH METHYL METHACRYLATE

In the present work, the kinetics of radical copolymerization in solution at the initial stages of polyglycol maleinate phthalates modified with nitrogen-containing compounds with methyl methacrylate in a ratio of 1:1 was studied. Cyclohexanone was used as a solvent, and benzoyl peroxide was used as an initiator. The study was carried out at temperatures of 50 and 60 °C by dilatometry using collapsible dilatometers and a centrifuge. 13 amine-containing compounds of different types were chosen as modifiers. Also, for comparison, the possibility of using amides and hydrazines as modifiers was checked. Polycondensation was carried out in an oil bath at 175 °C and with vigorous stirring with water withdrawal until a constant acid number was reached. It is shown that the addition of 0.1 mol/l modifier during the polycondensation of a mixture of maleic and phthalic anhydrides with ethylene glycol makes it possible to obtain an unsaturated oligoester, for which the temperature coefficient of the reaction of its copolymerization with methyl methacrylate is significantly reduced. This allows for non-isothermal curing to increase the volume of the copolymer block without the risk of overheating and destruction. Of the studied amines, para-aminoacetophenone turned out to be the most effective; its use as a modifier makes it possible to reduce the temperature coefficient of the reaction from 2.1 to 1.7. The rate of copolymerization at the initial stages for the studied modified systems decreases from 2 to 20 times. The results of the work allow us to propose a technology for the production of polymeric materials by molding them in blocks of much larger sizes than with the use of traditional unsaturated oligomers. Also, calculations were carried out according to a special technique and the maximum size of a copolymer block in the form of a cylinder was determined, in which the height is equal to the radius, which can be obtained by forming it in a non-isothermal mode in a thin layer form with convection air cooling and the maximum allowable temperature in the system is 90 °C. It is shown that the volume of such a block, when using some modified oligomers, increases significantly. Some physical and mechanical characteristics of the obtained copolymers with methyl methacrylate were determined, and it was shown that modification with nitrogen-containing compounds does not improve or worsen the studied characteristics.

Morphological Diversity in Diblock Copolymer Solutions: A Molecular Dynamics Study

Coarse-grained molecular dynamics simulations that incorporate explicit water-mediated hydrophilic/hydrophobic interactions are employed to track spatiotemporal evolution of diblock copolymer aggregation in initially homogeneous solutions. A phase portrait of the observed morphologies and their quantitative geometric features such as aggregation numbers, packing parameters, and radial distribution functions of solvent/monomers are presented. Energetic and entropic measures relevant to self-assembly such as specific solvent accessible surface area (SASA) and probability distribution functions (pdfs) of segmental stretch of copolymer chains are analyzed. The simulations qualitatively capture experimentally observed morphological diversity in diblock copolymer solutions. Topologically simpler structures predicted include spherical micelles, vesicles (polymersomes), lamellae (bilayers), linear wormlike micelles, and tori. More complex morphologies observed for larger chain lengths and nearly symmetric copolymer compositions include branched wormlike micelles with Y-shaped junctions and cylindrical micelle networks. For larger concentrations, vesicle strands, held together by hydrogen bonds, and “giant” composite aggregates that consist of lamellar, mixed hydrophobic/hydrophilic regions and percolating water cores are predicted. All structures are dynamic and exhibit diffuse domain boundaries. Morphology transitions across topologically simpler structures can be rationalized based on specific SASA measurements. PDFs of segmental stretch within vesicular assemblies appear to follow a log-normal distribution conducive for maximizing configuration entropy.

ТЕРМООКИСЛИТЕЛЬНАЯ УСТОЙЧИВОСТЬ ПРОТОНООБМЕННЫХ МЕМБРАН НА ОСНОВЕ СОПОЛИМЕРОВ СТИРОЛСУЛЬФОКИСЛОТЫ И N-ВИНИЛИМИДАЗОЛА

The differential scanning colorimetry (DSC) thermooxidative stability of new copolymers of styrene-sulfonic acid and N-vinylimidazole obtained by radical copolymerization in a DMF solution in an argon atmosphere has been studied

Structural–Morphological and Rheological Features of Joint Solutions of Cellulose and PAN Copolymer in N-Methylmorpholine-N-Oxide

Mixed 18% solutions of cellulose and PAN terpolymer containing methyl acrylate and methylsulfonate comonomers in N-methylmorpholine-N-oxide have been obtained over the entire range of compositions. All the obtained systems based on cellulose and PAN are biphasic, and the morphological features of the emulsions change from highly dispersed isotropic to fibrillar depending on the phase composition and the intensity of the deformation effect. At high shear stresses that emerge during preparation of the solutions in an extruder, all emulsions are characterized by the same microheterogeneous morphology, which is transformed into fibrillar by deformation. An IR spectroscopic study has established that in the preparation process, specific interactions occur between the functional groups of macromolecules of the cocomponents, leading to the formation of PAN/cellulose associates, which undergo hydrophobic repulsion along the interfaces. It is this process that initiates the fibrillation of the cellulose solution phase in the presence of a PAN solution during deformation. The rheological behavior of mixed solutions over the entire range of concentrations in continuous and dynamic modes at temperatures of 110–130°C is a direct consequence of the phase composition and morphological transformations occurring during deformation. Emulsion compositions characterized by viscoelastic properties that make it possible to successfully form composite fibers have been chosen.

Photoinduced Solubility Modulation in the Copolymers of Fluoroalkyl, Spiropyranyl, and Isobornyl Methacrylates

This article reports photoinduced solubility modulation in copolymer thin films derived from spiropyranyl, perfluoroalkyl, and isobornyl methacrylates. A random copolymer of spiropyranyl methacrylate (SPMA) and 1H,1H,2H,2H-perfluorooctyl methacrylate (FOMA) was first prepared in the absence of isobornyl methacrylate (IBMA). The resulting as-prepared thin film could be dissolved in highly fluorinated or fluorous solvents but became insoluble following exposure to UV light (λ = 365 nm) via the photoisomerization transformation of spiropyran units into merocyanine moieties. On the other hand, the incorporation of IBMA into the copolymer structure above a certain threshold resulted in copolymers exhibiting the opposite dissolution behavior. UV–vis spectroscopic measurements on the copolymer films and solutions indicated that dipolar attraction between the photoisomerized merocyanine moieties contributed to the decrease in solubility. The incorporation of IBMA into the copolymer chains diluted the merocyanine moieties and increased their glass-transition temperature, resulting in the disruption of the intermolecular attraction and an increase in the solubility of the UV-exposed polymer chains. These results suggested that stencils could be developed without additives to generate strong acid molecules or free radicals in polymer thin films. The proposed processing technique for fluoroalkylated copolymers was thus tested in the fabrication of orthogonal copolymer stencils and demonstrated to be a useful tool for the pixel patterning of chemically vulnerable organic light-emitting diodes.

Scalable preparation of efficiently self-healing and highly transparent omniphobic coating for glass

Omniphobic coatings with low contact angle hysteresis (CAH) are of great practical significance. Yet, the mass production of coating with high transparency and a long service life through a facile and scalable approach still remains a challenge. By constructing covalent bonds between glass substrate and coating, in this work, a facile approach for the preparation of slippery coating for glass by ultrasonically immersing the substrate in a copolymer solution was proposed, which is a promising material to meet all aforementioned requirements. Corresponding results showed that the CAH for water and hexadecane on the surface of coating are both lower than 5°, while the CAH for high-viscosity glycerol is around 13°. Also, the transmittance of the coated glass at a visual wavelength of 550 nm is as high as 93 %. Thanks to the thermal self-healability of the coating, the omniphobicity experienced sand drop abrasion, water cleaning and high-speed water impact can be regained. Still, the transmittance is over 90 %. Meantime, it is gratifying to see that the omniphobicity can be self-healed by using a portable hair drier at a designated area efficiently. This facile approach presented here shows potential in the scalable preparation of self-cleaning and anti-fouling coatings with high transparency.

Superabsorbent polymer with enhanced gel strength and heat resistance using itaconic acid‐based oligomer

AbstractThe preparation of an itaconic acid‐based oligomer and its polymerization with acrylic acid via aqueous solution copolymerization are described herein for application as novel superabsorbent polymers (SAPs). The structure of the SAP is characterized using Fourier transform infrared (FT‐IR) spectroscopy. In addition, the absorption properties of the SAPs with various oligomer contents and degrees of monomer neutralization are evaluated by measuring the free absorbency, centrifuge retention capacity (CRC), and absorbency under load (AUL) in 0.9 wt% saline solution. Further, the gel strengths and thermal stabilities are examined via rheological thermo gravimetric analyses. The results demonstrate that the introduction of the IA‐based oligomer into the SAP network is improves the AUL, gel strength, and thermal stability of the SAP. We found the best performance of an SAP using IA‐based oligomer with a CRC of 36.7 and AUL of 22.7 g/g.

Hyperbranched Copolymers of Methacrylic Acid and Lauryl Methacrylate H-P(MAA-co-LMA): Synthetic Aspects and Interactions with Biorelevant Compounds.

The synthesis of novel copolymers using one-step reversible addition-fragmentation chain transfer (RAFT) copolymerization of biocompatible methacrylic acid (MAA), lauryl methacrylate (LMA), and difunctional ethylene glycol dimethacrylate (EGDMA) as a branching agent is reported. The obtained amphiphilic hyperbranched H-P(MAA-co-LMA) copolymers are molecularly characterized by size exclusion chromatography (SEC), FTIR, and 1H-NMR spectroscopy, and subsequently investigated in terms of their self-assembly behavior in aqueous media. The formation of nanoaggregates of varying size, mass, and homogeneity, depending on the copolymer composition and solution conditions such as concentration or pH variation, is demonstrated by light scattering and spectroscopic techniques. Furthermore, drug encapsulation properties are studied by incorporating the low bioavailability drug, curcumin, in the nano-aggregate hydrophobic domains, which can also act as a bioimaging agent. The interaction of polyelectrolyte MAA units with model proteins is described to examine protein complexation capacity relevant to enzyme immobilization strategies, as well as explore copolymer self-assembly in simulated physiological media. The results confirm that these copolymer nanosystems could provide competent biocarriers for imaging and drug or protein delivery/enzyme immobilization applications.

Electron beam irradiation as a straightforward way to produce tailorable non-biofouling poly(2-methyl-2-oxazoline) hydrogel layers on different substrates

Uncontrolled accumulation of proteins and cells on implantable materials often leads to failure of their performance in vivo. The idea presented in this paper is the use of electron beam irradiation as a widely applicable, cost-effective, and defined method to produce non-biofouling hydrogel coatings to improve the biocompatibility and in vivo performance of implantable materials. Statistical copolymers poly[2-methyl-2-oxazoline-co-2-(3-butenyl)-2-oxazoline]s were deposited on different substrates and irradiated with beta radiation of different radiation doses (2–100 kGy). In the bulk state experiments, we found that the higher content of crosslinkable 3-butenyl units and a higher radiation dose resulted in more efficient crosslinking. Similarly, the irradiation of coatings demonstrated the high impact of the concentration of 3-butenyl units on crosslinking efficiency. Accordingly, the concentration of crosslinkable double bonds in the copolymer is crucial for the stability and homogeneity of the formed hydrogel layer. Stable and uniform hydrogel layers with thicknesses in the micrometer range were prepared from a 5 wt% copolymer solution. Depending on the preparation conditions, the hydrogel layers showed excellent non-biofouling properties with a low number of adherent cells. In addition, stiffness was dependent on the degree of crosslinking, and can thus be tailored for specific application in living tissue.

Electrosynthesis of silver metallonanocomposites in the 1-vinyl-1.2.4-triazole copolymer matrix with methacrylic acid

Silver nanocomposites were synthesized by the electrochemical method in the matrix of a copolymer of 1-vinyl-1,2,4-triazole with methacrylic acid, by combining the process of electrochemical polymerization with cathodic precipitation of metals on metal electrodes. In the electronic spectra of nanocomposites, absorption bands appear with a maximum in the region of 417–421 nm, which is typical for systems with zero valence silver. The IR spectra show that the polymer structure hardly changes during the formation of nanocomposites and films. The presence of silver in the amorphous polymer phase is indicated by the results of X-ray diffraction studies. The silver content in nanocomposites is 0–9%, which leads to an increase in the viscosity of nanocomposite solutions compared to solutions of the initial copolymers. Transmission electron microscopy data show that the synthesized nanocomposites consist of particles with a diameter of 1–12 nm, predominantly spherical.

PH-Responsive Water-Soluble Chitosan Amphiphilic Core–Shell Nanoparticles: Radiation-Assisted Green Synthesis and Drug-Controlled Release Studies

This work aims to apply water radiolysis-mediated green synthesis of amphiphilic core-shell water-soluble chitosan nanoparticles (WCS NPs) via free radical graft copolymerization in an aqueous solution using irradiation. Robust grafting poly(ethylene glycol) monomethacrylate (PEGMA) comb-like brushes were established onto WCS NPs modified with hydrophobic deoxycholic acid (DC) using two aqueous solution systems, i.e., pure water and water/ethanol. The degree of grafting (DG) of the robust grafted poly(PEGMA) segments was varied from 0 to ~250% by varying radiation-absorbed doses from 0 to 30 kGy. Using reactive WCS NPs as a water-soluble polymeric template, a high amount of DC conjugation and a high degree of poly(PEGMA) grafted segments brought about high moieties of hydrophobic DC and a high DG of the poly(PEGMA) hydrophilic functions; meanwhile, the water solubility and NP dispersion were also markedly improved. The DC-WCS-PG building block was excellently self-assembled into the core-shell nanoarchitecture. The DC-WCS-PG NPs efficiently encapsulated water-insoluble anticancer and antifungal drugs, i.e., paclitaxel (PTX) and berberine (BBR) (~360 mg/g). The DC-WCS-PG NPs met the role of controlled release with a pH-responsive function due to WCS compartments, and they showed a steady state for maintaining drugs for up to >10 days. The DC-WCS-PG NPs prolonged the inhibition capacity of BBR against the growth of S. ampelinum for 30 days. In vitro cytotoxicity results of the PTX-loaded DC-WCS-PG NPs with human breast cancer cells and human skin fibroblast cells proved the role of the DC-WCS-PG NPs as a promising nanoplatform for controlling drug release and reducing the side effects of the drugs on normal cells.

Nano aluminum-based hybrid flocculant: Synthesis, characterization, application in mine drainage, flocculation mechanism

Given the characteristics of high turbidity and trace emulsified oil in mine drainage, which leads to the problems of low settling efficiency and poor treatment efficiency in the coagulation/flocculation treatment process, there is an urgent need to develop efficient, economical, and stable flocculants. In this study, a new hybrid flocculant Al-P(AM-DMDAAC-BA) was synthesized by the solution copolymerization method, and its viscosity, molecular weight, and cationic degree were 1492.93 mL/g, 7.44 × 106 Da and 16.97%, respectively. The physical and chemical properties of Al-P(AM-DMDAAC-BA) were characterized by Fourier transform infrared spectroscopy (FTIR), Nuclear magnetic resonance (1H and 13C NMR), Transmission electron microscopy (TEM), X-ray diffraction (XRD), Scanning electron microscopy (SEM), Thermogravimetric (TG), and Zeta potential. SEM, Zeta potential, and laser particle size measurement characterized the properties of flocs. Batch wastewater treatment experiments analyzed the flocculation treatment efficacy. The results of the analysis are as follows. Aluminum hydroxyl complexes were attached to organic polymers via -Al-O-C- bonds. Acrylamide (AM), dimethyl diallyl ammonium chloride (DMDAAC) and butyl acrylate (BA) were linked to each other by Carbon-carbon double bond (-CC-). The aluminum-based complex is dispersed as nano-microspheres in the hybrid flocculant and cross-linked to the organic branched chains. Al-P(AM-DMDAAC-BA) is thermally stable and less susceptible to thermal decomposition. It possesses strong electrical neutralization ability and rapid floc growth ability. It has excellent turbidity removal (reduced to 7.96 ± 1.15 NTU) and emulsified oil removal (reduced to 0.23 ± 0.01 mg/L) performance. The flocculation mechanism is mainly attributed to the electro-neutralization of the hybrid flocculants and the adsorption bridging effect of organic branched chains.
