The effect of filler content and chemical modification on properties of polylactic acid/recycled low density polyethylene/nypa fruticans husk biocomposites

Nypa fruticans husk (NFH) filled polylactic acid (PLA)/recycled low density polyethylene (rLDPE) biocomposites had been prepared using Brabender Plasticoder EC PLUS at temperature 180˚C and rotor speed 50 rpm. The effect of NFH content and different types of chemical modifications on tensile proper...

The chemical modifications of NFH resulted positive effect on tensile and thermal properties of PLA/rLDPE/NFH biocomposites.

The treated PLA/rLDPE/NFH biocomposites with 3-APE/Enzyme have highest tensile strength, Young‘s modulus, and thermal stability compared to other chemical modifications of biocomposites.
