| 摘 要： | 以纤维素硫酸钠(NaCS)为聚阴离子，聚二烯丙基二甲基氯化铵( PDMDAAC)为聚阳离子，利用两者的界面反应制备了NaCS/PDMDAAC聚电解质复合膜。测量了复合膜表面静态接触角用以表征膜润湿性变化，研究了聚电解质浓度、分子量、反应时间等对接触角的影响。结果表明，复合膜为亲水膜，静态接触角随NaCS浓度、PDMDAAC分子量增大而减小，随PDMDAAC浓度、反应时间增大而增大。

| Abstract: | A new type of NaCS/PDMDAAC polyelectrolyte complex membrane prepared by interfacial reaction of sodium cellulose sulfate as polyanions and poly(dimethylallylammonium chloride)as polycations was proposed.The static contact angle of the polyelectrolyte complex(PELC)membrane surface was measured to characterize membrane wettability.The effects of concentration of polyelectrolyte,molecular weight,and reaction time on contact angle were investigated.It was found that NaCS/PDMDAAC PELC membrane was hydrophilic.It... |
