Improving the Mechanical Properties of Thermoplastic Polyolefins Using Recycled Low-Density Polyethylene and Multi-Walled Carbon Nanotubes

Thermoplastic polyolefin (TPO) has gained considerable attention because of having a combination rubbery and thermoplastic properties ease production. Their excellent weather resistance, low density, relatively cost make them attractive materials for the automotive, electrical, footwear industries membranes water treatment. main shortcomings are poor mechanical properties, especially at temperatures opposing trends stiffness toughness. In this paper, recycled density polyethylene (RLDPE) was integrated with ethylene-propylene-diene rubber (EPDM) incorporating very content carboxylated multi-walled carbon nanotubes (MWCNTs-COOH) to improve produced TPO nanocomposite. been prepared through 40, 50, 60 wt.% RLDPE EBDM. The improved composition then reinforced 0.1, 0.3, 0.5 MWCNTs-COOH produce nanocomposites. compounding its nanocomposites done by melt mixing followed heat pressing. Mechanical thermal behaviors were investigated. Tensile tests showed that TOP (60-40) is best concentration; storage modulus enhanced increasing concentration. addition, modulus, stress/strain toughness adding MWCNTs-COOH. Thus, due not only large aspect ratios but also interaction both matrix combatibilizer. results microstructural investigations nanocomposite using FTIR TGA confirmed between
