Plasma polymerization of unsaturated alcohols for deposition of hydrophilic thin film

Abstract

Plasma polymerization of propargyl alcohol (2-propynl-ol) produced highly hydrophilic polymer film on solid substrates. The hydrophilic property was further enhanced by using the same monomer containing 60% water. The polymer film deposited on a solid substrate preserved good adherence, transparency, and wettability after immersion in water for one month. Structural interpretation of the polymer molecule revealed presence of oxygen atoms in abundance as the forms of hydroxyl, carbonyl, and etheric oxygen groups. Applications of the polymer were attempted to improve characters of sensing materials in analytical chemistry and to control dissolution rate of a powder pharmaceutical in an aqueous medium. © 1988 IUPAC
