Effect of core-shell rubber toughening on mechanical, thermal, and morphological properties of poly (lactic acid)/multiwalled carbon nanotubes nanocomposites

The effect of core-shell rubber (CSR) toughening on mechanical and thermal properties of poly(lactic acid)/multiwalled carbon nanotubes (PLA/CNT) nanocomposites were investigated. The nanocomposites were prepared by direct melt blending method in a counter‐rotating twin‐screw extruder. The contents...
