摘要

应用静电纺丝技术

以聚苯乙烯和愈合剂的共混溶液为纺丝液

制备了含有愈合剂的功能纤维

并以其制备了具有自修复性能的纤维/树脂复合材料.通过扫描电子显微镜(SEM)、红外光谱(FTIR)、荧光显微镜等对纤维的形貌和结构进行了表征

探讨了纺丝溶液的组成对纤维形貌和结构的影响.纤维中愈合剂的含量随纺丝液中愈合剂浓度的增加而增大

但可纺性随之变差.通过SEM观察了所制备的复合材料表面预制裂纹的修复

在一定温度下裂纹处纤维中的愈合剂(分别为环氧和其固化剂)释放并进一步反应

经过愈合复合材料的拉伸强度提高了2.81 MPa

力学性能明显改善.

Abstract

Electrospinning technique was utilized to prepare healant-loaded composite fibers

with spinning solutions of polystyrene and healing agent.The morphology and composition of the resultant functional fibers were investigated by SEM

EDX

optical microscopy and FTIR.The influence of the concentration of healing agent in the spinning solution on the fibers morphology and structure was also discussed.The results indicated that the healing agent was loaded in the fibers relatively uniformly

and the amount of healant in the fibers increased gradually with its concentration in the spinning solution

whereas the spinnability declined.Composite of the asformed fibers and resin was prepared and the self-healing of micro-crack on the composite surface was observed by SEM.The healing agent in the fibers could be released under a certain temperature thus healed the micro-crack.The tensile strength of the composite increased 2.81 MPa after the self-healing process and the mechanical properties of the composite were improved obviously.
