其他摘要Well-defined polystyrene-co-poly(2,3,4,5,6-pentafluoro styrene) (PS-co-PPFS) copolymers were synthesized by atomic transfer radical polymerization (ATRP) in trifluorotoluene, fluorinated ionic liquid and trifluorotoluene/fluorinated ionic liquid solvent systems, respectively. The chain structure and component of such copolymers were characterized by H-1 NMR, F-19 NMR, elemental analysis and GPC. Porous films of PS-co-PPFS copolymers were fabricated by static breath-figure method in CS2, CHCl3 and CH2Cl2, respectively. The morphologies of such porous films were observed by scanning electron microscopy (SEM) and compared with those of PS homopolymer with similar molecular weight. The results showed that PS-co-PPFS copolymers with narrow molecular weight distribution (M-n = 5200 similar to 7900 g.mol(-1), M-w/M-n = 1.12 similar to 1.22) can be synthesized via ATRP in trifluorotoluene and fiuorinated ionic liquid, respectively. The SEM observation indicated that PS-co-PPFS copolymer porous films can be fabricated with CS2, CHCl3 and CH2Cl2 as solvent, respectively. While, different from PS analogues, PS-co-PPFS copolymer porous films showed less ordered pore structures with two different average pore sizes. The pores of such film fabricated in CHCl3 were in better order with two average pore sizes of 0.75 and 0.37 mu m, respectively.
