Comparison of the Mechanical Strength and Stiffness of MWNT-PMMA and MWNT-Epoxy Nanocomposites

摘要

The surface of multi-wall carbon nanotubes(MWNTs) was functionalised by covalent linking of long alkyl chains.Such functionalisation led to a much better tube dispersion in organic solvents than pristine nanotubes,favoured the formation of homogenous nanocomposite films,and yielded good interfacial bonding between the nanotubes and two polymer matrices,i.e.a thermoset (Epon 828/Jeffamine T-403 epoxy/amine) and a thermoplastic (PMMA).
