The effect of carbon nanotubes on viscoelastic behaviour of biomedical grade ul...
Rui Miranda Guedes; Celeste M. C. Pereira; Alexandra Fonseca; Mónica S. A. OliveiraNanocomposites of ultra-high molecular weight polyethylene reinforced with multiwalled carbon nanotubes (UHMWPE/MWCNT) have been prepared with different volume fractions of MWCNTs: 0.2, 0.4, 0.6, 0.8 and 1.0%. DMTA experiments were carried out using a TA Instruments Q800 equipment and the samples were cut from the compressed sheets of polymer and composites. The experiments were conducted on each sample at 12 d...
