  • 摘要: 为解决麦秸纤维/聚乳酸(WF/PLA)复合材料界面相容性较差的问题,以H2O2作为氧化剂处理麦秸,采用响应面试验法探究H2O2的pH、处理温度、质量比对氧化麦秸纤维(OWF)/PLA复合材料力学性能的影响,得到各因素对复合材料力学性能的影响规律。结果表明:pH和处理温度、pH和质量比、处理温度和质量比之间均表现出明显的交互作用。回归方程预测的最佳工艺参数如下:H2O2的pH为8.9,H2O2的处理温度为52.3℃,H2O2的质量比为2%。在此条件下,复合材料的拉伸强度和断裂伸长率分别为38.89 MPa和7.85%,较未改性前分别提高了15.64%和15.20%。FTIR结果表明,OWF中的部分羟基被H2O2氧化为羧基。SEM结果表明,OWF能够更好地与PLA进行结合,经过熔融共混后制备的复合材料之间具有更好的界面相容性。此外,XRD和DSC结果表明,H2O2的加入促进了聚合物的异相成核过程,使其结晶度有所提高。
