Formation Of Microcrystals On A Surface Of Commercial Chlorinated Polyvinyl Chloride Under The Action Of A High-Power Ion Beam Of Nanosecond Duration

The formation of well-faceted microcrystals on the surface of chlorinated polyvinyl chloride (CPVC) with the addition of ferrocene (Fe(C5H5)(2)) under the action of a high-power ion beam (HPIB) was found. Microcrystals are formed when the polymer is irradiated by an HPIB with a current density in the range of 70-120 A/cm(2). Microcrystals had a most probable transverse size in the range of 5-8 mu m. The maximum microcrystal growth rate was estimated as similar to 5 mu m/mu s. It is assumed that microcrystal growth occurs through redeposition of the ablation products and decomposition products of CPVC.
