淀粉的改性及其在可降解塑料和橡胶中的应用研究

淀粉作为一种天然高分子,由于其价格低,可再生,生物降解性好等优点,在材料制备与改性方面得到了人们的青睐.同时由于淀粉所固有的亲水性,难于加工性以及和石化材料间较差的相容性等也大大限制了其在非食品工业中的应用范围.本文介绍了国内外淀粉改性的最新进展及其尝试其在可降解塑料和橡胶方面的应用研究,并就目前该领域存在的一些问题作了初步探讨.

The Modification of Starch and Its Applications in Degradable Plastic and Rubber

Starch is one of the natural renewable polymers. Due to its low cost, availability from renewable resources and excellent biodegradability, starch has received considerable attentions in the preparation and modification of materials. At the same time, starch is also a poor choice in the applications of the nonfood industry for the reason of the mostly water soluble, difficult to process, and the poor compatibility between the petrochemical. In this paper, we shall introduce some new development about the modification of starch and its application in degradable plastic and rubber in domestic and foreign. We also make some primary discussions about the existed problems in these areas.
