Mechanical properties of PLA/PBS foamed composites reinforced by organophilic montmorillonite

Porous materials have specific properties, such as high surface area, high permeability, lightweight, and low thermal conductivity. In foaming process of thermoplastics, high melt viscosity is indispensable. Neither poly(lactic acid) (PLA) nor poly(butylene succinate) (PBS) has sufficient melt viscosity. In this manuscript, Organophilic montmorillonite (OMMT) was employed to improve the foaming performance PLA/PBS blends. Mechanical tests were...
