Hyperbranched polyethyleneimines were modified with methacrylated fluorosurfactants and aliphatic epoxides to provide a library of macromolecules with controlled chain ends and residual amine functionality. These materials were co-dissolved with a thermoplastic polyurethane-ether and the blends were subsequently deposited as films cast from solution. The surface chemistry of the cast films was determined...
Melt stirring of non-functional polymers such as poly(ethylene oxide) dimethylether (PEO–Me) and polystyrene (PS–H) with multiwalled carbon nanotubes (MWNTs) in the absence of solvent for 48h induced a substantial amount of polymer adsorption on the MWNTs. The chloroform extraction of the reaction products using centrifugation yielded black colored solutions exhibiting UV absorbance corresponding...
[60]Fullerene is produced by pyrolysis of corannulene between 650 and 1200 °C, (either with or without the presence of Pd/C or Co catalysts), 7, 10-bis(2,2′-dibromovinyl)fluoranthene (a corannulene precursor) at 700 °C, and of 11, 12-benzofluoranthene at 900–1000 °C.
