Abstract The role of deep sea environment in polymer transfer was investigated by studying poly(methylsilsesquioxane) (PMSQ) microspheres reinforced poly(butylene terephthalate) (PBT) composites. The results show that besides reinforcement in mechanical strengths, the incorporation of PMSQ enhances PBT transfer due to its unique chemical structure, appropriate size and soft characteristic. The transfer process of composites starts with PMSQ particle transfer, forming the initial transfer layer and growing to optical visible transfer film. The seawater pressure prolongs the transfer process and decreases adhesion of transfer film by preferentially saturating hydroxyl groups at PMSQ surface and freshly created dangling bonds at metallic counterface.

聚（甲基倍半硅氧烷）微球增强聚对苯二甲酸丁二醇酯复合材料在深海中的转移行为

摘要 通过研究聚（甲基倍半硅氧烷）（PMSQ）微球增强聚对苯二甲酸丁二醇酯（PBT）复合材料，研究了深海环境在聚合物转移中的作用。结果表明，除了机械强度的增强外，PMSQ 的掺入由于其独特的化学结构、适当的尺寸和柔软的特性而增强了 PBT 的转移。复合材料的转移过程从 PMSQ 粒子转移开始，形成初始转移层并生长为光学可见转移膜。海水压力通过优先饱和 PMSQ 表面的羟基和金属反面新产生的悬空键，延长了转移过程并降低了转移膜的附着力。
