Multifunctional Smart Polymer Coatings

Monomer feed rate regulates the chemical structure of smart plasma copolymer coating and its surface wettability in various pH environment. The combined effect of surface chemical compositions and surface roughness causes tunable wettability from superhydrophobicity to superhydrophilicity of smart plasma copolymer coatings. Further on, the presence of the carboxylic acid functional group in plasma copolymer coatings made this surface wettability switchable for different pH environment.
