高分子纳米合金膜的制备及其电磁性能的研究

The block copolymer polystyrene-b-poly[2-(trimethylsilyloxy)ethylene methacrylate] (PSt-b-PTMSEMA), PTMSEMA-b-PSt-b-PTMSEMA, poly(p-nitrophenylmethacrylate)-b-polystyrene-b-poly(p-nitrophenylmethacrylate) and polystyrene-b-polyvinylpyridine were synthesized using atom-transfer radical polymerization (ATRP).The effect of the structure of intiators and the ligand on the ATRP were studied too. The amphiphilic block copolymer were prepared by hydrolysis of PSt-b-PTMSEMA, the core-shell nanometer reaction flasks were prepared using microinverse phase methods, the nickel and cobalt cause chemical reactions in these reaction flasks and could be reduced easily, then the nanometer magnetic film were prepared. The effect of the concentration of the polymer, the concentration of the metal salt solution, and the mix speed and the properties of solvent were studied, some good results have been obtained.
