Synthesis of a Superhydrophobic and Stretchable Polymer Thin Film

Abstract

Waterproof elastic films are receiving a lot of attention as they can be used for the treatment of wearable electronics or other flexible devices. In this study, the polymer film with superhydrophicity and nanoscale ultrathin stretchable was designed and synthesized through iCVD (initiated chemical vapor deposition) method. This film is a synthetic film of water repellent PFOA (1H,1H,2H,2H-perfluorooctyl acrylate) and crosslinking agent V3D3 (1,3,5-trivinyl-1,3,5-trimethylcyclotrisiloxane ) copolymerized and optimized composition. With an elastic limit of more than 200%, the water contact angle was maintained at more than 150 degreee, and sufficient mechanical durability was achieved. If the performance was the same after the 2000cycles stretch test, it also has enough solvent resistance with optical transparency.
