BRIDGING FILMS FOR POROUS THIN FILMS

摘要

The disclosure provides methods and materials for preparing bridging films. In one aspect, the bridging films are non-porous and are suitable for protecting adjacent porous films. For example, the bridging films contact a porous film and protect the porous film from transfer of gases and/or liquids into the pores of the porous film. In another example, bridging films protect the porous film from abrasion.
