Tensile and Morphological Properties of Spear Grass (Imperata cylindrica) Filled Low Density Polyethylene/ Thermoplastic Soya Spent Powder Blends

This study investigate about the tensile and morphological properties of degradable polymer produce from low density polyethylene/ thermoplastic soya spent powder filled spear grass loading varied from 0-3 wt %. Meanwhile, ratio of LDPE/ TSSP which is 95:5 was used as matrix in this composite. The tensile strength increased up to addition of 1.5 wt% spear grass and decreased when 3 wt% spear grass was added. SEM micrograph showed fibrils formation for sample with 1.5 wt% spear grass as it has the highest elongation at break compared to 1 wt% and 3 wt % spear grass.
