Abstract

Radiofrequency plasma polymerization was investigated as a method to prepare ionically conductive membrane materials for biomedical sensors. Plasma copolymers of chlorotrifluoroethylene (CTFE) and trifluoromethanesulfonic acid (TFMSA) exhibited ionic conductivity three to four orders of magnitude higher than the water used to make the measurement and gave ATR-FTIR and ESCA evidence for retained sulfonic acid groups. Plasma homopolymerizations of CTFE and perfluoroallylphosphonic acid (PAPA) were investigated to determine suitable conditions for plasma copolymerization of the two monomers. Plasma homopolymerized CTFE had deposition rates varying from 4400 angstroms/h to 100 angstroms/h, was extremely hydrophobic, and showed spectroscopic evidence for a lightly branched, crosslinked fluorocarbon structure. Plasma homopolymerized PAPA deposited uniformly at approximately 780 angstroms/h, was extremely hydrophilic, and showed spectroscopic evidence for retained phosphonic acid groups. Plasma-polymerized PAPA had ionic conductivity two orders of magnitude higher than that of the water used to make the measurement. Increasing the discharge pressure from 30 m Torr to 100 m Torr resulted in decreased deposition rate for plasma homopolymerized CTFE and decreased monomer fragmentation in plasma homopolymerized PAPA.
