Effect of dispersions on vapour permeation resistance of acrylic sealants

Currently, acrylic sealants are widespread due to their environmentally friendly materials, ease of use, and low cost. Their compositions are constantly being improved. It allows ones to improve their quality and reduce the cost by selecting new substances for their manufacture. We obtained acrylic sealants with changing polymer base. The authors used acrylic and styrene acrylic dispersions obtained by emulsion polymerisation. The basis for sealants production is the mechanical mixing of the components and their further dispersion in the Dispermat VLOK dissolver. The main parameter to be determined is the vapour permeability resistance of the material layer. According to research results, the nature of the polymer base, degree of its bonding, type and amount of the filler used affected on vapour permeability of the sealing material. Moreover, increasing in film former temperature, viscosity, and pH causes increasing in tensile strength. By comparing the sealant samples on the basis of dry residue, we found increasing of the Shore hardness in samples with lower % index.

Fluorine-free approaches to impart photovoltaic systems with self-cleaning and anti-icing features

AbstractDust deposition on photovoltaic systems has a significant impact on the transmittance, temperature, and roughness, causing reductions in their power generation efficiency and lifetime. A promising approach to deal with this problem relies on the use of superhydrophobic coatings to impart the surfaces of these devices with self-cleaning properties. In this work, materials with different chemistry and morphology were added to an acrylic dispersion to create hydrophobic surfaces using a non-fluorinated coating simple strategy for glass substrates. Results showed that materials with more complex morphology, namely the spherical shape of silica nanoparticles, and the needle-like and prism-like structures of zinc oxide, imparted the glass with higher water contact angles. All coatings prepared displayed self-cleaning features and good adhesion to the glass substrate. Coatings comprising silica nanoparticles, zirconia and alumina modified with HDMTS were the best ones to prevent ice formation. In terms of chemical stability, all the coatings resisted acidic conditions close to acid rain pH and solvents with mild polarity. Therefore, the coatings proposed hold great potential to expel dust contaminants and prevent ice formation of photovoltaic devices, increasing their lifetime and power generation efficiency.

High solid and low viscosity waterborne polyurethane acrylate with excellent anti-corrosion and anti-bacterial performances

The design and preparation of great corrosion resistance and high-solid waterborne polyurethane dispersion with low viscosity is still a challenge in the field of the polyurethane industry. Herein, we developed a simple method involving a core-shell process to prepare a core-shell structured waterborne polyurethane acrylate dispersion (WPUAD). First, isobornyl acrylate, a derivative of natural product borneol, dihydroxylated by a thiol-ene click reaction was used to prepare oil-based polyurethane acrylate as prepolymer A (core) and waterborne polyurethane acrylate as prepolymer B (shell). Then, the core-shell WPUAD was obtained by mixing and emulsifying the two prepolymer at a certain ratio. The study reveals that the core-shell structured WPUAD not only has a low viscosity (~1330 mPa.s) but also holds a high-solid content (~ 60 wt%). At the same time, the highly solid WPUAD has excellent stability with no breast breakage even after more than 1 year of storage. In addition, various electrochemical measurements, water contact angles, and water absorption tests were performed to determine the anti-corrosive properties of the WPUAD-derived coatings. The results show that the WPUA coatings exhibit significantly enhanced anticorrosion with respect to the single prepolymer B derived coatings, which is attributed to their high cross-linking density resulting from the core-shell structure and the introduction of hydrophobic isobornyl acrylate. In addition, because of the introduction of the dihydroxylated isobornyl acrylate as chain extenders, the WPUA coating has great anti-bacterial adhesion properties with an anti-bacterial efficiency of 82.3 %. We believe that our work provides a generic preparation method to obtain a commercially available high-solid WPUAD with excellent anti-corrosion properties.

Study of the effect of silicate fillers on the structural and rheological properties of acrylic dispersions

This work reports the rheological properties of an acrylic aqueous dispersion filled with hollow aluminosilicate microspheres and highly dispersed amorphous silicon dioxide studied by using rotational viscometry. It was established that an increase in the degree of filling with hollow microspheres leads to a significant increase in the viscosity of the aqueous dispersion, which results in technological difficulties when applying coatings to the surface. The introduction of a small amount of silicon dioxide additive leads to a decrease in the structural strength and effective viscosity of the aqueous dispersion of the acrylic copolymer, which allows significantly reducing the viscosity and regulating the rheological characteristics of highly filled systems, which is decisive in the technology of their application. The combination of such fillers as silicon dioxide and hollow aluminosilicate microspheres in an aqueous dispersion of an acrylic copolymer allows simultaneously reaching a number of positive phenomena: a reduction in the viscosity of the material during application (without dilution) due to the use of high shear rates and an increase in the rate of dispersion structuring after application, and also allows achieving sedimentation resistance during storage and transportation.

Investigation of the properties of a water-based acrylic dispersion modified with an ionic liquid, surfactant, and thickener.

The sustainable development of the paint and varnish industry is a prerequisite for action to minimize the negative environmental impact of paint products. They consist not only in reducing the emission of harmful VOC substances into the atmosphere but also in modifying the composition of the paint material in order to improve the properties of the coatings and at the same time reduce the amount of waste. Selection of the appropriate composition of the water-borne composition is still a problem to be solved. Therefore, aqueous polymer dispersions of Arlberdingk AC 2514 containing an acrylic resin modified with an ionic liquid of didecyldimethylammonium nitrate (DDANO3) were tested. Non-ionic surfactants (Rokanol L-10 and Rokacet S-24), polyurethane thickener (DSX 1514), and mineral thickener (bentonite) were also used for stabilization. The influence of individual components on changes in the stability and particle size of dispersion systems was investigated. Physicomechanical tests of coatings obtained from polymer dispersion systems were also performed. Studies have shown that with the increase in the amount of DDANO3 in the system, the particle size of the varnish composition decreases and the gloss and relative hardness of the coatings decrease. The optimal amount of DDANO3 in the dispersion is 1.5% w/w. DSX 1514 increased the stability, reduced the migration rate of the dispersion particles, and improved the elasticity and impact resistance of the protective membranes. It has been shown that the stability varies depending on the type of thickener and surfactant (SAA) used. SAA increases the value of the TSI (Turbiscan Stability Index), which takes the values of 3.8 (0.3g bentonite) and 3.6 (0.6g bentonite), respectively, with Rokanol L-10 16% w/w. Water-soluble acrylic resin with the tested additives can be potentially used for the production of stable dispersions with extended life.

Fire Behavior and Adhesion of Magnesium Phosphate Coatings for the Protection of Steel Structures

This paper presents the main properties of magnesium phosphate cements (MPCs) to be used as coatings for passive fire protection of steel structures. The influence of various additions, i.e., waste glass powder, fly ash, a styrene–acrylic dispersion, and expandable graphite, on the fire behavior and the adhesion to steel substrates of magnesium phosphate coatings is presented in this paper. The setting time of studied cements is extended when magnesia, the main component of MPCs, is partially replaced with fly ash or/and waste glass powder. The mineralogical composition of these cements, before and after thermal treatment at 1050 °C, was assessed by X-ray diffraction and could explain the changes in compressive strength, volume, and mass recorded for the thermally treated specimens. The studied magnesium phosphate coatings have a good adherence to the steel substrate (assessed by a pull-off test) both before and after direct contact with a flame (fire test) and decrease the temperature of the steel substrate by 30% with respect to the one recorded for the uncoated steel plate.

Emulsifier-free (meth)acrylic colloids stabilized by cationic monomer containing two charged moieties

Emulsifier-free cationic polymer colloids produced by emulsion polymerization have gained important relevance for diverse applications. However, the control of colloidal characteristics is still challenging due to the cationic monomers structure, in which the charge is placed between two hydrophobic moieties making them less efficient in providing colloidal stabilization. This challenge was confronted by employing a minor quantity of cationic monomer containing two charges, styrenic 1,4-diazabicyclo[2.2.2]octane, to provide colloidal stability to waterborne (meth)acrylic dispersions. For first time, high throughput production of cationic dispersions with controlled colloidal and film properties is achieved. High solids content stable dispersions comprising monodispersed particles with 170 nm average diameter and high charge density ranging 24–180 μC·cm−2 are produced, giving rise to films with tunable mechanical and water resistance. This work offers a novel concept for colloidal stabilization of polymer colloids and can be extended towards stabilization of challenging colloidal dispersions or design of novel surfactants.

Synthesis and Characterization UV-Curable Waterborne Polyurethane Acrylate/Al2O3 Nanocomposite Coatings Derived from Jatropha Oil Polyol

A new UV-curable waterborne polyurethane acrylate/alumina (UV-WPUA/Al2O3) coatings were successfully developed. The waterborne polyurethane acrylate (WPUA) dispersion was synthesized by reacting jatropha oil polyol (JOL) with isophorone diisocyanate (IPDI), 2,2-dimethylol propionic acid (DMPA), and 2-hydroxyethyl methacrylate (HEMA) via in-situ and anionic self-emulsifying methods. The WPUA/Al2O3 dispersion was formulated by various sonicating concentrations of alumina nanoparticles (0.3, 0.6, 0.9, and 1.2 wt%) into WPUA dispersion. The UV-WPUA/Al2O3 coatings were obtained with 75 wt% oligomers, 25 wt% monomer trimethylolpropane triacrylate (TMPTA), and 3 wt% of a commercial photoinitiator (benzhophenol) for UV-curing were used. The effect of Al2O3 nanoparticles on WPUA coatings was analyzed by FTIR, surface morphology, and coating performance properties such as pendulum hardness, pencil hardness, scratch resistance, and adhesion test. FTIR revealed the formation of JOL, neat UV-WPUA, and UV-WPUA/Al2O3 coatings, respectively. FESEM/EDX demonstrated that Al2O3 nanoparticles at the lower loading (up to 0.6 wt%) were well-dispersed correlated with contact angle (CA). The hardness property can reach 63.4% at the lower concentration of the Al2O3 addition 0.6 wt%. The adhesive strength, scratch hardness, and scratch resistance were greatly improved to 5B, 5H, and 2N, respectively. The preparation method offered in this study is an effective and convenient approach to producing UV-WPUA/Al2O3 coatings. The enhancement of the properties with the lesser concentration of Al2O3 nanoparticles (≤ 0.6 wt%) addition in this study shows a new promising potential as surface coating application for several major industrial areas, such as marine, transportation, and biomedical field with major economic and environmental benefits.

The creep performance of bio-based and synthetic lining adhesives at different environmental conditions

Canvas paintings are prone to environmental ageing. Hence, the structural conservation of canvas paintings may require lining, a process in which a secondary canvas is adhered to the reverse of the damaged original canvas to provide additional support. Choosing the optimum adhesive in combination with a lining method is crucial and yet challenging, as they should preferably be mechanically and chemically stable and reversible for at least 100 years. Comprehensive data on thermal and long term mechanical behaviour of prevalently used adhesives and their bonded assemblies to canvas is scarce and yet necessary to enable conservators for a proper choice of the materials in terms of durability. In this study, four prevalently used adhesives in the conservation of canvas paintings are investigated and their creep performance is evaluated and benchmarked at three different temperatures and environmental relative humidities (RHs). These adhesives are either bio-based (animal glue-starch paste and beeswax-dammar resin mixtures), or synthetic (BEVA® 371 and an aqueous Plextol™ D540/K360 dispersion mixture). Differential Scanning Calorimetry (DSC) technique is used to study the thermal transitions at different RHs. T-peel and lap shear tests are performed to determine the fracture behaviour and shear strength respectively. An in-house built creep set-up equipped with environmental control is developed which allows investigation of the mechanical creep for different canvas bonded assemblies. The results demonstrate the effects of temperature and relative humidity on the creep behaviour of lined canvases, which are related to their physical response. Moreover, the animal glue-starch paste shows the best creep mechanical performance for this application, while the Plextol TM acrylic dispersion mixture in combination with Mist-Lining is a better alternative when both environment and reversibility are considered.

Spray and foam application of chemical binders to pulp fiber airlaids

Pulp fiber airlaid nonwovens were bonded with three binder formulations in a spray and foam process. The binders were: a commercial acrylic dispersion binder, a commercial bio-containing acrylic binder; and a citric acid-carboxymethyl cellulose mixture (CACMC) (1:1 by-weight). The binder solutions were applied at same concentrations onto A4-size airlaid sheets (80 gsm) under a vacuum with 2-sided spraying and 1-sided foam coating. The sheet structure, dry and wet tensile properties, and total absorption capacity were compared. The foam application densified and bulk bonded the sheets, whereas the spray application induced surface bonding. These factors fundamentally influenced the measured sheet properties. The dry tensile strength was linearly correlated with the relatively low binder dosages. The CACMC binder exposed the differences in the binder application processes well, and lead to strong sheets with small elongation and highly application method-dependent absorption capacity compared to acrylic binders.

DIRECTED REGULATION OF THE STRUCTURAL AND RHEOLOGICAL PROPERTIES OF HEAT-INSULATING ACRYLIC AQUEOUS DISPERSIONS USING THE COMBINED USE OF HYDROPHILIC AND HYDROPHOBIC SILICATE FILLERS

The formation technology and performance characteristics of coatings based on aqueous dispersions are largely determined by the properties of the initial film-forming materials, which should ensure uniform thin-layer distribution on the substrate surface and the formation of coatings with the required technological complex of properties. Among them, due to their functional properties and relatively low cost, the most widespread are water-dispersion polymer coatings based on acrylic film-formers. In this paper, mathematical models of the structural and rheological dependences of heat-insulating acrylic aqueous dispersions are considered depending on the combined content of hydrophilic-hydrophobic fillers. To describe these dependencies, it is advisable to use equations of the second degree. According to the mathematical theory of experiment, the second-order orthogonal central compositional design makes it possible to predict the behavior of the response function. Carrying out an experiment in accordance with this plan makes it possible to establish the analytical dependence of the response function on the corresponding factors in the form of a polynomial equation of the second degree. The main response functions were: conditionally static yield stress, viscosity at the minimum rate of onset of fracture (initial effective viscosity), viscosity of the “destroyed” structure according to the Newtonian nature of the flow, activation energy of viscous flow at minimum, average and maximum shear rates. On the basis of the established dependences, the optimal ratios of hydrophobized aerosil and aluminosilicate microspheres were selected, the combined use of which makes it possible to reduce shear stresses to create a homogeneous aqueous acrylic dispersion, to predict the activation energy at various technological stages of preparation and application of heat-insulating coatings. The established results made it possible to create a hydrophilic-hydrophobic aqueous acrylic dispersion, which, without the use of surfactants, makes it possible to simplify the production technology of heat-insulating water-dispersion coatings, namely, to exclude the stage of pretreatment of fillers, to reduce the rotation speed of the frame mixer, and also to increase the kinetic stability of the finished dispersion.

DEVELOPMENT OF SELECTIVE GROUTING COMPOSITIONS BASED ON BITUMINOUS EMULSIONS FOR WATER INSULATION WORKS

To increase the efficiency of water inflow isolation in oil wells, selective grouting compositions are preferred. The use of selective isolation methods provides for selective clogging of water inflow channels while maintaining the permeability of oil-saturated reservoir intervals. The mechanism of selectivity realization for different groups of grouting compositions is shown. It is noted that the selectivity of the action of these compositions is significantly affected by the permeability heterogeneity of the formation. In this case, the water primarily flows through the high-permeable interlayers, where the grouting composition will be pumped in a larger volume than in the low-permeable interlayer during water insulation works. In this paper, we continue to study selective grouting compositions that clog the pore space with a material that is subsequently soluble in oil and insoluble in water. The possibility of using bitumen emulsions, including commercially available road emulsions, is analyzed. The use of bituminous emulsions as water-insulating compositions has a number of advantages: due to the low viscosity of the direct emulsion, it easily penetrates into the porous medium. At the same time, bituminous emulsions have high thermal stability. The resulting bitumen film is impervious to water and is sufficiently resistant to aggressive media (acids and alkalis). The objects of the study were used bitumen road emulsion cationic grade EBDK B-52 and acrylic dispersions, which were intended to increase the adhesion of bitumen to the surface of rock and metal. Commercially produced reagents of the Lacroten brands (E-081, E-31, E-082, E-43), Lacryl 4443 were used as acrylic dispersions. Studies of bituminous emulsions and acrylic dispersions for adhesion to the surface of metal, carbonate and terrigenous rocks have been carried out, from which it follows that acrylic dispersions with a low pH (3.0-3.6) are an effective means of processing samples. Filtration studies indicate the selective properties of the bitumen emulsion. When injecting B-52 bitumen emulsion for both the bulk model and the ideal crack model, there is a general tendency to reduce water permeability: 32.8 % for the bulk model and 33.6 % for the ideal crack model. When conducting filtration studies with the initial injection of acrylic dispersion followed by injection of the emulsion, in all experiments, filtration attenuation is observed in both the water-saturated and oil-saturated reservoir models. According to the results of the conducted studies, for the isolation of water-saturated interlayers, it is proposed to carry out works according to the scheme of selective isolation using bituminous emulsion B-52; and when carrying out works on the elimination of behind-the-casing flows, disconnecting water-filled layers and eliminating the leakage of production columns in the coupling joints, sequential injection of acrylic dispersion and bituminous emulsion is provided.

Functional aqueous-based polyaniline inkjet inks for fully printed high-performance pH-sensitive electrodes

pH sensors are extremely useful in various applications such as health, food and environmental monitoring. Due to this fact the development of planar, low-cost and high-performance pH sensors that can be fabricated in large scale are highly appreciated. In this work we fabricated a polyaniline-based potentiometric pH sensor using two printing techniques. The working electrode was fabricated by printing a carbon ink layer onto Valox® by screen printing and subsequently modifying its active area by printing with a polyaniline ink by inkjet printing. Different water-based formulations of the polyaniline ink using acrylic dispersions as binders were tested in order to optimize printability, adhesion, rub resistance and functionality of the printed electrodes. These electrodes showed an outstanding sensitivity (up to 69.1 mV/pH), slightly higher than polyaniline electrodes fabricated by electropolymerization onto carbon paste electrodes and also comparable to glass electrodes. Moreover, their response to synthetic sweat was analyzed, demonstrating that there are suitable for application in wearable technology.

Siloxane-modified waterborne UV-curable polyurethane acrylate coatings: Chemorheology and viscoelastic analyses

The effects of molecular weight of PDMS on chemorheology and viscoelastic behavior of siloxane modified waterborne UV-curable polyurethane acrylate dispersions (Si-WUPAs) were assessed via a photo rheometer as a versatile tool for in situ observation of chemical and mechanical characteristics during photopolymerization reaction. The roles of PDMS soft segment and its Mw on the rheological behavior were examined followed by exploring the flow curves of Si-WUPA system. The viscosity of Si-WUPA samples decreased with increasing shear rate, showing a pseudoplastic behavior for high-molecular-weight PDMS. However, the unmodified sample and specimens containing dual soft segments of PTMG and low Mw of PDMS revealed a Newtonian behavior. The curing process was accomplished using a photoinitiator to induce polymerization of acrylate double bonds at 40 °C and 60 °C, signifying a-three-step curing process. Enhanced drying time and gelation points were observed upon increasing Mw and content of PDMS. Correspondingly, the storage modulus diminished due to incomplete curing because of contribution of more flexible PDMS chains to reaction. Thermomechanical properties of UV-cured Si-WUPAs films were systematically studied via DMTA, revealing two different behaviors depending on the Mw of PDMS. Si-WPUAs systems showed enlarged width of tanδ peak in half of heights unconditionally, suggesting increased incompatibility and non-uniformity of the final film caused by micro-phase separation of PDMS chains. Mechanical properties were also inspected by tensile test confirming the DMTA results. Tensile isotherms of cured Si-WPUA specimens were remarkably sensitive to both Mw and the content of PDMS.

Increasing the Uniformity of Nano-Dispersed SiO<sub>2 </sub>Distribution in Polymeric Binder of Composite Material

Ultrasonic dispersion of a silica hydrosol is compared with the effects of mechanical activation through the combined action of high shear stresses, ultrasound and cavitation. This action leads to breaking the siloxane bonds and increasing the content of silanol groups. The mechanical activation of binary silica system with acrylate dispersion promotes a chemisorption of oligoacrylate with the formation of Si – O – C and Si – C bonds. The effect of modification of oligoacrylate on the formation of a graft-copolymer and the stiffness of a composite material was evaluated.

Hydroxyl‐terminated polybutadiene based waterborne polyurethane acrylate emulsions: Synthesis, characterization, and damping property

AbstractA new kinds of waterborne polyurethane acrylate (WPUA) dispersions were synthesized based on isophorone diisocyanate (IPDI), hydroxyl‐terminated polybutadiene (HTPB), 1, 4‐butanediol (1, 4‐BDO), polytetramethylene ether glycol (PTMG), dimethylolpropionic acid (DMPA), 2‐ethylhexyl acrylate (EHA), and methyl methacrylate (MMA) as main raw materials. The influence of the HTPB content on the particle size, storage stability of the WPUA dispersions and the damping property of cured films were studied by using dynamic light scattering (DLS), dynamic mechanical analysis (DMA), respectively. It can be found the WPUA dispersions have a good stability and the damping temperature range of loss tangent (tan δ) >0.3 reaches a maximum (−26.6–79.14°C) when the content of HTPB is 20%. The HTPB based WPUA could be applied to damping material.

Surface Activation of Polylactic Acid-Based Wood-Plastic Composite by Atmospheric Pressure Plasma Treatment.

Wood-plastic composite (WPC) based on a polylactic acid (PLA) matrix is a promising material since it is biobased, degradable, sustainable, and 3D printable. However, due to its coloring, visible layers after 3D-printing, and small build volumes of these printers, a coating or gluing of parts might be required. This study investigates the influence of a dielectric barrier discharge (DBD) plasma treatment of PLA-based WPC to activate the surface and improve, e.g., coating capabilities. X-ray photoelectron spectroscopy (XPS) measurements showed the oxidation of the surface due to the formation of carbonyl and carboxyl groups. Laser scanning microscopy revealed a surface roughening after the treatment. Contact angles of water and diiodomethane decreased significantly after the plasma treatment and the consecutively calculated surface free energy increased. Finally, two practical adhesion tests revealed an improvement of the applied acrylic dispersion coating’s adhesion to the WPC surface: The assigned cross-cut class improved, and the pull-off strength increased from 1.4 to 2.3 N/mm2.

Plasma Treatment of Polypropylene-Based Wood-Plastic Composites (WPC): Influences of Working Gas.

In this study, a polypropylene (PP)-based wood–plastic composite with maleic anhydride-grafted polypropylene (MAPP) as a coupling agent and a wood content of 60% was extruded and specimens were injection molded. The samples were plasma treated utilizing a dielectric barrier discharge (DBD) setup with three different working gases: Ar/O2 (90%/10%), Ar/N2 (90%/10%), and synthetic air. This process aims to improve the coating and gluing properties of the otherwise challenging apolar surface of PP based wood–plastic composites (WPC). Chemical analysis with X-ray photoelectron spectroscopy (XPS) and Fourier-transform infrared spectroscopy (FTIR) showed the formation of oxygen-based functional groups on the surface, independently from the working gas used for the treatment. Laser scanning microscopy (LSM) examined the surface roughness and revealed that the two argon-containing working gases roughened the surface more than synthetic air. However, the contact angle for water was reduced significantly after treatment, revealing measurement artifacts for water and diiodomethane due to the severe changes in surface morphology. The adhesion of acrylic dispersion coating was significantly increased, resulting in a pull-off strength of approximately 4 N/mm2, and cross-cut tests assigned the best adhesion class (0), on a scale from 0 to 5, after plasma treatment with any working gas.

Mechanochemical Synthesis of BaTiO3 Powders and Evaluation of Their Acrylic Dispersions.

Barium titanate is a ferroelectric perovskite with unique electric properties; therefore, it is widely applied in the fabrication of inorganic coatings or thin films, capacitors, or in the production of devices for energy storage and conversion. This paper describes the mechanochemical synthesis of BaTiO3 from BaO and TiO2 using a ball mill. XRD analysis allowed concluding that barium titanate was formed after 90 min of mechanochemical grinding. It was also proved by spectroscopic analysis and the band corresponding to Ti–O vibrations on obtained Fourier Transform Infrared (FT-IR) spectra. The specific surface area of obtained powder was 25.275 m2/g. Next, formed perovskite was dispersed in an acrylic poly(ethylene glycol) (superabsorbent polymer suspension, SAP) suspension prepared using microwave radiation. Final suspensions differed in the concentration of SAP applied. It was proven that the increase of SAP concentration does not affect the acidity of the suspension, but it does increase its dynamic viscosity. A sample with 83 wt.% of SAP reached a value of approximately 140 mPa∙s. Dispersions with higher values of SAP mass fraction exhibited lower sedimentation rates. Molecules such as SAP may adsorb to the surface of particles and thus prevent their agglomeration and make them well monodispersed. Based on the performed experiments, it can be concluded that acrylic poly(ethylene glycol) suspension is a suitable fluid that may stabilize barium titanate dispersions.
