Surface Modification of Silicones

Abstract

The ability to controllably modify the surface properties of a material with treatments that are sufficiently thin not to significantly affect bulk properties has become an important aspect of the development and application of polymers and advanced materials. This is the case with silicone polymers such as polydimethylsiloxane (PDMS). Although PDMS is one of the lowest surface tension polymers in common use, needs exist to lower as well as raise surface energy. Examples of the former type include a variety of low-soiling, anti-deposition coatings and sealants for substrates as diverse as textiles, masonry and solar-energy devices, as well as specialized release applications such as release liners for PDMS-based silicone pressure-sensitive adhesives. The most familiar example of the latter type of need to raise surface energy is to enhance adhesion to PDMS substrates, but there are numerous other needs including biomaterials such as tissue culture surfaces with optimum cell growth characteristics, ocular materials with good tear wettability, and low friction catheter polymers.
