Nanowire formation in Si-based polymer thin films using a heavy ion beam is discussed in terms of energy
density deposition along ion tracks. Gelation of the polymer along the ion track results in cross-linking to
produce nanowires with size and number density controllable by selecting appropriate ion beam characteristics
and polymer materials. Ion bombardment of poly(carbosilane) (PCS), PCS−poly(vinylsilane) blend polymer,
and poly(methylphenylsilane) produces nanowires with radii of 7−30 nm depending on the type of ion beam.
The difference in size is shown to be related to the efficiency of the cross-linking reaction considering the
deposited energy distribution along the ion tracks.
Glass fiber reinforced plastics (GFRPs) with cyanate ester resin/epoxy resin, bismaleimide resin/epoxy resin, and bismaleimide-triazine resin as matrices were developed for the
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
