Surface Chemistry and Wettability of Plasma Copolymer Coatings

Various methods of polymer surface tailoring have been studied to control the changes in wetting behavior. Polymers having precisely controlled wetting behavior in a specific environment are of great interest in biomaterial engineering. The controlled wetting behavior can be obtained by combining surface chemistry and morphology. Plasma assisted polymer surface modification technique have played a significant part to control surface chemistry and morphology. This book focuses on radio frequency (RF) plasma copolymerization of octafluorocyclobutane and acrylic acid (C4F8-co-AA) and investigations regarding surface chemistry, surface wettability, coating kinetics, as well as coating stability. Main achievements in this book are summarized below. This book has demonstrated a novel approach to fabricate surfaces with tailored wettability by merely controlling plasma polymerization parameters. The controlled wettability can be used to design filters with selective wettability for oil-water separation industry. Moreover, this technique will be helpful to design the pH-responsive biomaterials for tumor-targeted drug delivery.
