摘要：In this study, poly propylene (PP)/potato starch (PS) blend films are prepared using the two roll millmachine. The biodegradability of the films is investigated by soil burial method over a period of 4 months. Thepercentage weight loss of the bio-composites in the compost soil burial test is increasing with increasing PS content.The biodegradability of the bio-composites is enhanced with increasing starch content because the PS is easily attackedby microorganisms. Any changes in the various properties of the PP/PS before and after degradation are monitoredusing weight loss, FTIR spectroscopy, a scanning electron microscope (SEM) for surface morphology, a thermogravimetric analyzer (TGA) for rapid determination of starch content and a differential scanning calorimeter (DSC) forcrystallanity. It can be concluded from the results that use of these bio-composites will reduce the environmentalproblems associated with waste pollution and the study findings support the predicted application of bio-composites asgreen-composites or eco-materials.
