摘要/Abstract

摘要： 以过氧化二异丙苯为引发剂，甲基丙烯酸缩水甘油酯（GMA）为单体，通过熔融反应制备了聚己内酯（PCL）接枝甲基丙烯酸缩水甘油酯（PCL-g-GMA），用傅里叶红外光谱（FTIR）和核磁共振氢谱（¹H-NMR）表征了接枝物的化学结构，并以PCL-g-GMA为增容剂，考察了其添加对竹纤维/聚己内酯（BF/PCL）复合材料结构与性能的影响。研究结果表明，FTIR和¹H-NMR分析结果证实了GMA已成功接枝到PCL上。PCL-g-GMA添加后，竹纤维与PCL的界面相容性得到明显改善，复合材料力学性能显著提升，吸水率下降。在PCL-g-GMA添加质量分数为10%时，复合材料拉伸强度、断裂伸长率比未增容BF/PCL复合材料分别增大了80%和70%。

Abstract: Polycaprolactone-graft-glycidyl methacrylate(PCL-g-GMA) was synthesized by blending the melted PLA with GMA with dicumyl peroxide as initiator. The grafting copolymer was characterized by FTIR and ¹H-NMR spectroscopic analyses. The effect of PCL-g-GMA addition on the structure and properties of bamboo fiber/polycaprolactone composite was investigated. The result showed that:the GMA was successfully grafted onto polycaprolactone,which was confirmed by FTIR and ¹H-NMR spectroscopic analyses. The interfacial compatibility,mechanical and water absorption properties were greatly improved by PCL-g-GMA. When 10% content of PCL-g-GMA was addied,the bamboo fiber/polycaprolactone composite showed optimal mechanical properties,with an improvement of 80% in tensile strength and 70% in elongation at break,compared to those without PCL-g-GMA.

Key words: polycaprolacton, bamboo fiber, glycidyl methacrylate, melt blending, compatibilizer
