Mechanical and Thermal Properties of Rubber Toughened Poly(lactic Acid)/ Multiwalled Carbon Nanotubes Nanocomposite

The effect of core-shell rubber (CSR) as impact modifier for Poly(lactic acid)/multiwalled carbon nanotubes (PLA/CNT) nanocomposites was investigated. In this work, the nanocomposites were prepared by direct melt blending method in a counter-rotating twinscrew extruder. The contents of CSR were vari...
