【摘要】 采用热致相分离法制备聚苯硫醚多孔结构,选用PEG作为成核剂,研究其对孔结构的影响.文章主要讨论不同聚合物浓度下成核剂的分子量以及含量对微孔结构的影响,从而得到不同结构、孔径范围在0.5～0.05μm的多孔结构.更多还原

【Abstract】 The different molecular weight Polyethylene glycol(PEG) was chose to be as the nucleating agent to investigate the effects of nucleating agents on the porous structure of polyphenylene sulfide(PPS) via thermally induced phase separation(TIPS).The pore structures were changed with the addition of PEG,due to the different mechanism on pattern formation.Moreover,some effecting factors,such as the molecular weight and concentration of PEG,were used to control the pore structure and size.With addition of nucleating agent,it can be estimated that the pore size(radius) should be about 0.5~0.05μm更多还原
