Paper Title:
Enhanced UHMWPE Reinforced with MWCNT through Mechanical Ball-Milling
  Abstract

In this work, nanocomposites of ultrahigh molecular weight polyethylene (UHMWPE) reinforced with multiwalled carbon nanotubes (MWCNTs) were evaluated for their ability to produce nanocomposites with superior mechanical properties. As homogeneity of the nanocomposite plays an important role into final mechanical properties, mechanical ball-milling is used to prepare homogeneous UHMWPE/MWCNTs powders, where special emphasis is given to milling-time optimization. Mechanical ball-milling seems to be a suitable and rather simple technique for preparing nanocomposites even outside laboratory conditions and it is presented here as an interesting technique for nanoscience industrial applications. A fact that is worth noting since the great majority of research breakthroughs fail due to lack of industrial accomplishment. The powder mixture was further processed through compression moulding in a hot plate press. The impact of milling time on mechanical properties of the nanocomposites was evaluated. Nanocomposites with different volume fractions of MWCNTs were prepared using the optimized milling time, processed via compression moulding and their mechanical properties were evaluated. It was observed an enhancement of the Young’s modulus of about 80%, for higher volume fractions of MWCNTs (1.0%), as compared with the pure UHMWPE.
