Crosslinking poly(acrylic glycidyl ether) honeycomb film by cationic photopolymerization and its converting to inorganic SiO2 film

Highly ordered hexagonal patterns of homopolymer poly(Glycidyl methacrylate) (PGMA) film was successfully fabricated via static breath figure. This honeycomb film was further modified to enhance the solvent resistance as well as thermal stability through cationic photo-crosslinking of the epoxide via UV irradiation. The obtained film could be used as template to assemble SiO2 particles via chemical vapor deposition of TEOS under mild condition.
