Title Mechanically and thermally enhanced multiwalled carbon nanotube-graphene hybrid filled thermoplastic polyurethane nanocomposites
Date 01.03.2015
Abstract Multiwalled carbon nanotube (MWCNT)–chemically reduced graphene oxide (CRGO) hybrid in different weight ratios were prepared by solution mixing. MWCNT–CRGO (1:1) hybrid exhibited better dispersion stability in dry THF and characterized. Subsequently, it was used as reinforcing filler in thermoplastic polyurethane (TPU) nanocomposites by solution intercalation. Further investigations showed that 0.25 and 0.50·wt.-% MWCNT–CRGO (1:1) loaded TPU exhibit significant improvement in thermal stability (40·°C at 50% weight loss) and storage modulus (206% at 50·°C) respectively. This is attributed to homogeneous dispersion and strong interfacial interaction between TPU and filler.
