摘要:

以淀粉和可生物降解的PCL或PHBV等疏水性脂肪族聚酯为原料, 制备了淀粉基的Semi-IPN材料. 加入PCL或PHBV等疏水性大分子的使淀粉基Semi-IPN材料的耐水性能相对于原淀粉有很大的改善, 通过热处理和溶剂化作用能使Semi-IPN的耐水性进一步提高.

Abstract:

The semi-IPN between starch and biodegradable PCL or PHBV was prepared by using HDI as the cross linking reagent under solution conditions. Their water\|resistance properties were investigated by comparing with cross-linked starch net works without PCL or PHBV. It was found that the water resistance of the Semi\|IPN can be further improved by means of heat treatment or solvent treatment methods, respectively.

Key words: Semi-IPN; Starch; Water-resistance
