| 摘 要： | 用化学气相沉积(CVD)聚合法制备的聚氯代对亚苯基二亚甲基(PPX-C)膜,除了具有聚对亚苯基二亚甲基(PPX)膜的保形涂覆和物理性能外,还具有更好的粘附能力。研究表明:PPX-C膜具有优异的耐溶剂性和抗化学氧化性能;氯的引入使膜的玻璃化转变温度降低,室温柔性增强,动态力学阻尼性能增大,热降解起始温度比PPX膜低,主链降解温度与PPX膜相近。此外,氯的引入对膜的亲水性能影响不大,但膜的水汽渗透率却因此明显降低,与PPX膜相比PPX-C膜具有更好的防潮性能。

| Abstract: | Poly(chloro-p-xylylene)(PPX-C) was prepared by chemical vapor deposition(CVD) polymerization.Its chemical structure was confirmed by FTIR.It is found that PPX-C membrane has the same good solvent resistance and high chemical oxidation stability as poly(p-xylylene)(PPX),the initial degradation temperature and T_g of PPX-C membranes are reduced with the introduction of chloride as side groups.With the introduction of chloride,the polymer becomes amorphous and soft,and the dynamic(mechanical) damping properties of PPX-C are improved.It seems that the hydrophilicity of PPX-C membrane is similar to that of PPX,while the vapor permeability of PPX-C membranes is reduced compared with PPX.Thus the moisture-proof ability of PPX-C membrane is improved significantly. |
