Novel toughened polylactic acid nanocomposite: Mechanical, thermal and morphological properties

The objective of the study is to develop a noveltoughenedpolylacticacid (PLA) nanocomposite. The effects of linear low density polyethylene (LLDPE) and organophilic modified montmorillonite (MMT) on mechanical, thermal and morphologicalproperties of PLA were investigated. LLDPE toughened PLA nanocom...
