摘要
介绍了淀粉/PVA生物降解塑料的制备方法,并分析了溶液流延法、共混挤出和模压成型法的优缺点,阐述了这些技术在淀粉/PVA塑料制备中的进展。针对淀粉塑料的吸水性和生物降解性,对淀粉/PVA塑料的研究方法作了论述,同时对淀粉/PVA塑料的应用也作了介绍,最后展望了淀粉/PVA塑料的发展方向及前景。
The preparation and application of starch/polyalcohol vinyl(PVA) composites are introduced, The advantages and disadvantages of solution casting, blending extrusion and moulding are discussed. The water resistance and degradation of starch/PVA composites are the most important properties,so the study methods of water resistance and degradation are reviewed. At last, the development trend of starch/PVA composites is forecasted.
