Abstract

Polymer (C₆H₅C)_n, (i.e. (RC)_n, R equals Ph equals Phenyl), synthesized by chemical reaction, is a pyrolytic precursor to carbon. The carbon-based network backbone structure in polymer, under pyrolysis, could be converted to hard, abrasive and highly reflective solid. The powder of this solid can easily scratch glass and quartz plates. After pyrolysis, the films, coated by using (RC)_n on various substrates Si, silica, Al₂O₃, exhibit linear temperature-dependence property of its electrical surface resistance. By SEM, diamond crystallites with grain size from several tens nanometers to several microns have been observed. It proves that under heat decomposition, carbon-based network backbone structures have converted to sp³- bonded carbon phases.
