Fluoroalkylation of aryl ether perfluorocyclobutyl polymers

摘要

Post functionalization of aryl ether perfluorocyclobutyl (PFCB) polymers with fluoroalkyl side chains was accomplished with Umemoto’s FITS reagents. The fluoroalkylated PFCB polymers (20 % functionalized) showed increases in both hydrophobicity and oleophobicity. Static contact angle for hexadecane was increased after fluoroalkylation from 0o to greater than 30o for the two PFCB polymers tested. Increased oil repellency makes these materials potential candidates for various coatings applications.
