摘要: We report the syntheses of azido- and acetylene-functionalized poly(N-isopropylacrylamide) (PNIPAm) copolymers their use in fabrication ultrathin thermoresponsive microcapsules through direct covalent layer-by-layer (LbL) assembly using click chemistry. The clickable poly[N-isopropylacrylamide-co-(trimethylsilyl)propargylacrylamide] poly(N-isoropylacrylamide-co-3-azideopropylacrylamide) were prepared atom transfer radical polymerization (ATRP) at 0 °C a synthesized dansyl-labeled initiator CuBr/Me6TREN (hexamethylated tris[2-(dimethylamino)ethyl]amine) catalyst complex 2-propanol. After removing protective trimethylsilyl groups, these PNIPAm assemble alternately onto azido-modified silica particles aqueous media reactions catalyzed by copper sulfate sodium ascorbate. template, remained stable because presence covalently bonded triazole units; microcapsules...
