Composites of fluoropolymers (FKMs) and nanocarbon fillers have been considered as sealing materials for hydrogen fuel storage. The research found that the glass transition temperatures for FKMs adsorbed onto SWCNTs and CB were higher than the bulk value, with a more remarkable extent for SWCNTs. The difference in FKM mobility between the two fillers was attributed to the manner of chain adsorption via atomic-scale surface roughness, rather than surface chemistry.
Composites of fluoropolymer (FKM) and nano-carbon fillers have been considered as sealing materials for hydrogen fuel storage. We here characterize, structurally and dynamically, FKM chains adsorbed on single-walled carbon nanotubes (SWCNTs) and carbon black (CB), which were prepared by a solvent leaching method.
