Coordination-Polymer-Derived Cu-CoO/C Nanocomposite Used in Fenton-like Reaction to Achieve Efficient Degradation of Organic Compounds.

In this paper, carbon-matrix-supported copper (Cu) and cobaltous oxide (CoO) nanoparticles were obtained by using coordination polymers (CPs) as a precursor. The aqueous solutions of copper methacrylate (CuMA) and cobalt methacrylate (CoMA) were preferentially prepared, which were then mixed with anhydrous ethanol to fabricate dual metal ion coordination polymers (CuMA/CoMA). After calcination under an argon atmosphere, the Cu-CoO/C nanocomposite was obtained. Scanning electron microscope (SEM) and transmission electron microscope (TEM) showed that the material has banded morphology, and the dual functional nanoparticles were highly dispersed in the carbon matrix. The prepared material was used in a heterogeneous Fenton-like reaction, with the aim of replacing traditional ferric catalysts to solve pH constraints and the mass production of ferric slime. The obtained nanocomposite showed excellent catalytic performance on the degradation of methylene blue (MB) at near-neutral conditions; the discoloration efficiency is about 98.5% within 50 min in the presence of 0.15 mmol/mL H2O2 and 0.5 mg/mL catalyst. And good reusability was verified via eight cycles. The plausible pathway for MB discoloration and the possible catalytic mechanism was also proposed.

Decomposition mechanisms of self-polishing copolymers for antifouling coating materials through first-principles approach

Density functional theory calculations were performed to explain the decomposition mechanisms of selected self-polishing copolymer (SPC) molecules like tributyltin (TBT), zinc methacrylate (ZMA), copper methacrylate (CMA), and triisopropylsilyl acrylate (TIPSA). The comparison between the different activation energies of the SPC molecules indicated that ZMA and CMA could be polished faster than TBT and TIPSA; moreover, ZMA and CMA exhibited stronger adsorption energy and lower activation energy than TBT and TIPSA. The results also indicate that the configuration and chemical species of the pendant atoms in the functional group of the SPC molecules are essential for their antifouling performance.

Fabrication of Homogeneous Metal-Organic Hybrid Composite from Copper Containing Methacrylate Copolymer Through Layer-by-Layer Film Processing and e-Beam Irradiation

Nanocomposites with homogeneous dispersion of metal species have attained great attention due to their potential applications in various fields. Here, copper ion containing methacrylate copolymers were prepared by polymerization of copper methacrylate complex. The copper ion containing hybrid nanocomposite films were fabricated by layer-by-layer (LBL) assembly of copper ion containing methacrylate copolymers and transparent polyamic acid (PAA). LBL process was carried out with spin-assisted coating of PAA and dip-coating of copper ion containing methacrylate copolymers. The copper ion containing composite films were modified by thermal treatment and e-beam irradiation to reduce metal ions, resulting in higher mechanical properties. Modulus of modified copper metal-organic hybrid composite films was investigated by nano-indentation experiment.

Preparation of copper containing methacrylic polymers and their application for the copper patterns

Copper containing methacrylic polymers were prepared by the polymerization of a copper methacrylate complex (Cu[CH2C(CH3)COO](COD), where COD=1,5-cyclooctadiene) with different methylmethacrylate and methacrylic acid compositions. These polymers were found to be soluble in many organic solvents including THF and chloroform. Copper nano-networks or aggregated nanoparticles were obtained when a THF solution of the polymers was reduced using an aqueous sodium borohydride solution. When a thin film of the polymers coated on a silicon wafer was irradiated with an electron beam, nanoparticles were produced on the irradiated area, while the non-irradiated areas could be washed away with a weak base developer, such as a tetramethylammoniumhydroxyde (TMAH) aqueous solution, to produce a copper pattern through an electron beam lithography process.

Metal ion‐imprinted polymer microspheres derived from copper methacrylate for selective separation of heavy metal ions

AbstractMicrobeads of metal ion‐imprinted polymers (MIIPs) were prepared by a novel precipitation polymerization technique, in which copper methacrylate monomer and ethylene glycol dimethacrylate crosslinker were copolymerized in a rotary evaporator. The prepared microbeads had mono‐ or narrow size dispersity, and their sizes increased from 1 to 4 μm with decreasing solvent amount or increasing initiator concentration. The absorption capacity and selectivity of the imprinted polymer for copper ion were determined in the presence of various competitive metal ions. As results, adsorption equilibrium was quickly achieved in about 10 min with high absorbability (about 90%). The effects of pH, initial metallic ion concentration, and MIIP bead size on the absorption capacity were investigated. The Cu(II)‐imprinted polymers exhibited extremely high selectivity, which was much higher than that of corresponding blank polymers. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2008

Selective Solid-Phase Extraction of Trace Copper Ions in Aqueous Solution with a Cu(II)-Imprinted Interpenetrating Polymer Network Gel Prepared by Ionic Imprinted Polymer (IIP) Technique

An Cu(II)-imprinted interpenetrating polymer network (IPN) gel of epoxy-diethylenetriamine and methacrylic acid-acrylamide-N,N′-methylene-bis-(acrylamide) was synthesized by the ionic imprint polymer (IIP) technique. The first polymer network is formed by epoxy gelation with diethylenetriamine. The other is formed by copper methacrylate co- polymerization with acrylamide and cross-linker N,N′-methylene-bis-(acrylamide). The adsorption–desorption characteristics of the IPN gel as a highly selective solid-phase extraction (SPE) and preconcentration adsorbent for Cu2+ from aqueous solution were investigated. The experimental results show that trace Cu2+ ions can be quantitatively enriched at pH 5 with recovery >95%. The maximum static adsorption capacity of the ion-imprinted functionalized gel adsorbent was 76 mg g−1. Comparing with non-imprinted IPN gel, the imprinted IPN gel has higher adsorption capacity and selectivity for Cu2+ by the static adsorption–desorption experiment. Simultaneously, the times of adsorption equilibration and complete desorption were remarkably short. The precision (RSD) for 11 replicate adsorbent extractions of 20 ng mL−1 Cu2+ was 3.4%. The established procedure was applied to two real water samples with satisfactory results. The prepared ion-imprinted IPN gel adsorbent was shown to be promising for solid-phase extraction coupled with atomic absorption spectrometry (AAS) for the determination of trace copper in real samples. In addition, the coordination interaction of Cu2+ and functional groups of the IPN gel adsorbent was primarily discussed by FT-IR spectra.

Gamma ray-induced copolymerization of copper (II) methacrylate: A way of access to copper-based synthetic micro- and macroporous resins

Copper methacrylate undergoes high-yield copolymerization with hydroxiethylmethacrylate in the presence of 1,1,1-tris(hydroximethyl)propane trimethacrylate under γ-rays irradiation at room temperature. The bluish-green materials are characterized by bulk expanded volume measurements and infrared and ultraviolet-visible spectroscopy, and appear to be able to slowly release an appreciable percentage of the metal center embodied in the polymer network.
