Investigation of Tribological Properties of Hybrid HDPE Polymer Nano Composites

High-density polyethylene (HDPE) is a thermoplastic polymer, having various
applications when used as a primary phase in polymer nanocomposites. However, pure
HDPE is vulnerable to fail in tribological properties, particularly bearing applications.
Pure HDPE is susceptible to failure in tribological applications owing to the absence of
branches in its polymeric chains which make easy for the chain to slide past easily over
one another. The high tendency of nanoparticle aggregation in the polymer matrix usually
restricts the enhancement in nanocomposite properties. The inter-facial effect between the
nanoparticles and the polymer matrix is a critical problem for all types of nanocomposites.
Nanofillers (CaCO3/Nano clay) in this research project was developed by masterbatch
melt compounding technique.
