Synthesis and surface structure of polyester/poly(dimethylsiloxane)/polyester triblock copolymers and its reorientation under water

摘要

The outstanding properties of poly(dimefhylsiloxane) (PDMS) make them broad application in industrial areas for the bulk and surface modification of polymeric system. Some of the most interesting properties of PDMS include extremely low glass transition temperatures (high chain mobility), biocompatibility, hydrophobicity (water repellency), and low surface energy.1 Despite their unique properties, pure PDMS has too weak mechanical property to be used directly and shows the thermodynamic incompatibility with most other polymers due to its low solubility parameter.
