Structure of nanofibers derived from polycarbosilane using the polymer blend technique

Electrospinning of Direct Carbonizable Phenolic Resin-based Nanofibers

“…The post cure treatment, however, is the lengthy process, e.g. the precursor fibers should be soaked in an acid solution containing hydrochloric acid and formaldehyde and heated to 110°C at 0.2°C/min and held for 16 h to cure the resin [3]. Therefore, in the present study, directly carbonizable resolphenol formaldehyde resin not requiring its post cure treatment was used instead of novolac type.…”
