Nanosilver/poly(2-acrylamido-2-methylpropanesulfonate sodium) (nano-Ag/PAMPS) composites were synthesized by a microwave synthesis method. The mechanism of catalytic reduction of Ag ion by atomic nitrogen (from PAMPS) was explored. The composites were characterized by the ultraviolet-visible spectroscopy, x-ray diffractometry, transmission electron microscopy, x-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy, and thermogravimetric analysis (TGA). The results show that Ag nanoparticles (AgNPs) possessed face-centered cubic structure and they were homogeneously dispersed in PAMPS matrix. XPS analysis reveals the interaction between AgNPs and PAMPS matrix. TGA proves that the thermal stability of the pure PAMPS was higher than that of the nano-Ag/PAMPS composites.

Polyacrylate microgel emulsion was prepared by emulsion polymerization using styrene, α-n-butyl acrylate and methyl methacrylate as monomer, polyoxyethylene octylphenol ether (TX-30) and sodium dodecyl sulfate(SDS) as combine emulsifier, divinyl benzene and ammonium persulfate (APS) as initiator，respectively. The prepared microgel was analyzed by a variety of measurment methods, such as Fourier transform infrared spectroscopy and transmission electron microscopy. The effect of microgel on the rheological properties of adhesives, leveling, mechanical properties and pigment printing performance was studied. The rhelogy and the color fastness of the pigment printing binder of printed fabrics were measured by rheometer and friction color fastness test instruments, respectively. At the same time, the mechanical properties of the adhesive film was measured by strength tester. The results show that the thixotropy, leveling and mechanical properties of adhesive printing binder and pringting quality of coating fabrics were improved when the microgel was added.

The poly(methyl methacrylate) with single-caped halogen (PMMA-Br) was synthesized by atom transfer radical polymerization (ATRP) method under ultrasonic irradiation, with ethyl α-bromopropionate as the initiator and CuBr/2, 2-bipyridine (BPy) as the catalyst. Then the block copolymer poly(methyl methacrylate)-b-polystyrene was synthesized in cyclohexanone solution containing styrene as comonomer and PMMA-Br as the macromolecular initiator as same as the above synthesis condition. Nano-copper/poly(methyl methacrylate)-b-polystyrene composites was successfully prepared by NaBH4 as reductant in the polymerization system. The homopolymer, copolymers, and nanocomposites were characterized by means of FT-IR, 1H NMR, GPC, XRD, XPS, and TEM, and the results showed that the molecular weight of the block copolymer was controlled, and there existed interaction between copper particles and PMMA chain, and that ordered-assembly behaviors of block copolymer, induced by the nano-copper, were investigated by HTEM.

Nanocopper (nano-Cu)/poly(acetoacetoxyethyl methacrylate (AAEM)-styrene (St)) (P(AAEM-St)) composites were synthesized by reducing copper acetate solution in AAEM and St monomer by ultrasonic technique without adding emulsifier. The morphology, structure, thermal stability, and the interaction between Cu nanoparticles (NPs) and P(AAEM-St) matrix of the composites were characterized using ultraviolet-visible spectroscopy, X-ray diffractometer, transmission electron microscopy, X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA), respectively. The results show that Cu NPs possessed face-centered cubic structure, and they were homogeneously dispersed in P(AAEM-St) matrix. XPS and FTIR analyses reveal the interaction between Cu NPs and C¼O of the acetoacetoxy in the copolymer of AAEM and St. TGA proves that the thermal stability of the pure P(AAEM-St) is higher than that of the nano-Cu/P(AAEM-St) composites.
