本文研究了割手密接枝共聚物增强玉米淀粉基绿色复合材料。(Ss)制备了甲基丙烯酸甲酯（MMA）及其与丙烯酰胺（Mm）、丙烯腈（AN）、丙烯酸（AA）的共混物。以间苯二酚-甲醛（Rf）为交联剂，制备了不同交联剂用量的玉米淀粉复合材料，并对其理化性能、热性能和力学性能进行了研究。基质和复合材料被认为是热稳定性比天然玉米淀粉骨干。进一步通过土壤堆肥法对基质和复合材料进行生物降解研究。通过FT-IR和扫描电子显微镜（SEM）技术，生物降解的不同阶段进行了评估。S.发现spontaneum L纤维增强复合材料表现出更好的拉伸强度。另一方面，Ss-g-聚（MMA）增强复合材料表现出最大的压缩强度和耐磨性比其他接枝共聚物增强复合材料和基本基体。(C)2010爱思唯尔有限公司版权所有。
In this paper, corn starch based green composites reinforced with graft copolymers of Saccharum spontaneum L. (Ss) fiber and methyl methacrylates (MMA) and its mixture with acrylamide (Mm), acrylonitrile (AN), acrylic acid (AA) were prepared. Resorcinol-formaldehyde (Rf) was used as the cross-linking agent in corn starch matrix and different physico-chemical, thermal and mechanical properties were evaluated. The matrix and composites were found to be thermally more stable than the natural corn starch backbone. Further the matrix and composites were subjected for biodegradation studies through soil cornposting method. Different stages of biodegradation were evaluated through FT-IR and scanning electron microscopic (SEM) techniques. S. spontaneum L fiber-reinforced composites were found to exhibit better tensile strength. On the other hand Ss-g-poly (MMA) reinforced composites showed maximum compressive strength and wear resistance than other graft copolymers reinforced composite and the basic matrix.
