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.
