Surface Charactreistics of Polyphenylene Sulfide(PPS) Film Treated by Discharge Plasmas.

Abstract

Polyphenylene sulfide film was treated with low-temperature oxygen, nitrogen, and argon plasmas; argon sputter etching, and low-temperature helium/argon plasma under atmospheric pressure, and then the surface characteristics were investigated by means of critical surface tension and ESCA measurement. Critical surface tension and the O 1S intensities in ESCA spectra were increased considerably after discharge treatments. By helium/argon atmospheric low-temperature plasma treatment, the N 1S and O 1S intensities increased remarkably. From wave form separation of C 1S and S 2p spectra, it was found that oxygens incorporated in the polymer are present in the forms of -C-O-, -COO-, -S(=0)-, and -S(=0) 2−
