采用氯磺化和- so2cl与烯丙胺、乙二胺和去离子水反应的方法对Kevlar 49纤维进行表面改性，提高其与2,2-二[4-（4-马来酰亚胺氧基）苯基]丙烷（BMPP）树脂的粘附性。利用扫描电子显微镜（SEM）和电子能谱分析（ESCA）分别研究了纤维表面形貌的变化和纤维表面引入的表面官能团。从ESCA分析结果可以看出，凯夫拉纤维的表面成分与体成分存在显著差异。氯磺化后，碳的表面浓度明显降低。随后与乙二胺、烯丙胺和去离子水的反应也改变了纤维的表面组成；乙二胺和烯丙胺处理降低了O/N比。另一方面，水解处理提高了O/N比。年代……
Kevlar 49 fibers were surface-modified by chlorosulfonation and subsequent reaction of -SO2Cl with some reagents (allylamine, ethylenediamine, and deionized water) to improve the adhesion to 2,2-bis[4-(4-maleimidophenoxy)phenyl]propane (BMPP) resin. The change in fiber surface morphology and the surface functional groups introduced to the surface of the fiber were investigated by scanning electron microscopy (SEM) and electron spectroscopy for chemical analysis (ESCA), respectively. From the results of ESCA analysis, it was confirmed that the surface composition of the Kevlar fibers was significantly different from that of the bulk composition. After chlorosulfonation, the surface concentration of carbon was markedly decreased. The subsequent reaction with ethylenediamine, allylamine, and deionized water also changed the surface composition of the fiber; e.g. treatment with ethylenediamine and allylamine decreased the O/N ratio. On the other hand, the O/N ratio was increased by hydrolysis treatment. The s...
