Effects of the sublimation rate of di-p-xylylene on the crystallinity of parylene C deposited at different temperatures

Abstract

Poly(chloro-p-xylylene) was synthesized in a manner similar to poly(p-xylylene) using Gorham's method at various cryogenic temperatures. the effect of the sublimation rate of dimer on the kinetics of deposition, crystallinity, and crystalline structure was studied. Increasing the sublimation rate of the dimer increases the deposition rate similar to that of poly(p-xylylene). However, an increase in crystallinity, in contrast to Parylene N, is observed, although, in general, Parylene C has lower crystallinity relative to Parylene N. at lower temperatures, in the region minus 50 to minus 60 degree C, a rod-type morphology is observed similar to Parylene N. the surface topology of samples synthesized at minus 196 degree C is totally different from that of Parylene N. All low temperature synthesized samples are amorphous.
