Surface Modification of Silk Fabric with Perluoroalkanoyl Peroxide.

Perfluoroalkanoyl peroxides (PFPO) were applyed to the surface modification of silk fabrics. The modification with PFPO proceeded under quite moderate conditions. PFPO reacted specifically with tyrosine residues of silk on the surface, and hydrophobic perfluoroalkyl groups were introduced to the surface effectively. The modification with PFPO influenced the wettability and electrostatic property of silk fabric. Based on the results of ESCA analysis, the amounts of fluorine atoms on the surface were less than those by the CF4 plasma modification.
