Morphological study of SiO₂ biocomposite: article

Industries are pursuing towards biocomposite technologies by using plant fibres as the reinforcement materials. There are presence of silica in the plant fibres and generally act as a defense mechanism for the plants against herbivores. Silica biocomposite will be prepared by mixing silica fiber along with linear low-density polyethylene (LLDPE) and undergo grafting via extrusion in an extruder. This study is done to study the morphology of SiO₂ biocomposite and the effect of SiO₂ towards the biocomposite strength. The results are obtained by performing scanning electron microscopy (SEM) analysis with variation of different SiO₂ insertion based on the effect of cutting techniques and the surface of the sample being rubbed by sand paper.
