对竹纤维增强聚酰胺树脂复合材料界面改性剂及其界面改性机理进行研究，以聚乙二醇和马来酸酐为原料，用热催化法合成具有线型结构的羧化聚醚。通过红外光谱分析表明，在聚醚链上成功地接枝马来酸酐；经羧化聚醚界面改性剂改性后，羧化聚醚中的马来酸酐可与竹纤维中的羟基发生酯化反应；聚酰胺树脂端氨基和酰胺键中的亚氨基与羧化聚醚中马来酸酐发生酰胺化反应。经2％羧化聚醚改性后，竹纤维聚酰胺树脂复合材料强度性能指标和热变形温度均有大幅度地提高，竹纤维增强效果显著。

英文摘要：

A modifying agent of interface and modifying mechanics of bamboo fiber reinforced polyamide resin composite were studied. Polyethylene glycol and maleic anhydride were used as materials, carboxylic polyether that was used as agent of modifying composite interface was synthesized by using heat catalysis method. Carboxylie polyether of linear structure was successfully grafted by maleic anhydride through using fourier transform infrared spectroscopy. Maleic anhydride which had powerful reacting activity in carboxylic polyether could have a fast esterification reaction with hydroxy in the plant fiber. After the reaction of carboxylic polyether and polyamlde resin, the end amino and imido of polyamide resin had amidation reactions with maleic anhydride in carboxylic polyether. When carboxylic polyether charge was 2%, the strength properties and heat distortion temperature of the composite greatly raised. There was good interface connection between fiber and polyamide resin.
