Effect of Graphene Nanoplatelets and Paraffin Oil Addition on the Mechanical and Tribological Properties of Low-Density Polyethylene Nanocomposites

摘要: Polymeric nanocomposite materials have solved many problems due to their extensive applications such as aerospace, automobiles, coatings, and packaging materials. Low-density polyethylene (LDPE)/graphene nanoplatelets (GNPs) impregnated by paraffin oil (PO) were fabricated a hot compression technique. Elastic modulus was calculated results of test that conducted on the testing nanocomposites using universal machine. Microhardness LDPE its composites measured Vickers microhardness Tribological properties investigated pin-on-disc tester at 20 N normal load, $$1.2~\hbox {ms}^{-1}$$ sliding velocity, 212 m distance. The showed elastic LDPE/GNP are higher than pure then gradually decreased adding PO contents. proved lower coefficient friction (COF) wear rates in comparison with LDPE. By contents composites, COF increased. Wear specimens’ surfaces imaged scanning electron microscope.
