摘要
用３种二酰氯和己内酰胺对Ｋｅｖｌａｒ进行了表面化学接枝。考察了纤维表面、结晶温度和基体ＰＦ尼龙Ⅱ＃（即石油发酵尼龙Ⅱ＃）的γ－辐照等因素对Ｋｅｖｌａｒ／ＰＦ尼龙界面形成横晶的影响。辛二酰氯能够最有效地提高Ｋｅｖｌａｒ诱发ＰＦ尼龙Ⅱ＃的结晶能力，其界面结晶形态还与结晶温度和基体的性质密切相关。
Kevlar was chemically grafted with three kinds of diacrylholide and caprolactam. The nature of the fiber surface, crystalline temperature and the γ-radiation dose (R) of the PF nylon matrix(petroleum fermented nylon) were investigated as the couses of concerning the formation of the interface transcrystalline. The results show that fibers treated with octandioyl are of the best effect to induce PF nylon to form the transcrystalline, and the morphology of the transcrystalline is also related to the temperature and the nature of the PF nylon matrix.
