Abstract In this work, we designed an emulsion method to prepare polydimethylsiloxane microspheres in polyvinyl alcohol aqueous solution. Here, polyvinyl alcohol was utilized as both emulgator/dispersant and raw material, and homogeneous polydimethylsiloxane microsphere/polyvinyl alcohol composite hydrogels were fabricated. This strategy avoided the aggregation/adhesion of polydimethylsiloxane microspheres, and provided new thought for compositing the immiscible phases. The as-obtained composite hydrogels showed relatively high equilibrium water content and swelling ratio, as well as enhanced water retention and compressive modulus.

聚二甲基硅氧烷微球/聚乙烯醇复合水凝胶的制备及性能研究

摘要 在这项工作中，我们设计了一种乳液法在聚乙烯醇水溶液中制备聚二甲基硅氧烷微球。在此，以聚乙烯醇作为乳化剂/分散剂和原料，制备了均质聚二甲基硅氧烷微球/聚乙烯醇复合水凝胶。该策略避免了聚二甲基硅氧烷微球的聚集/粘附，并为合成不混溶相提供了新思路。所获得的复合水凝胶显示出相对较高的平衡水含量和溶胀比，以及增强的保水率和压缩模量。
