Morphology and Mechanical Property of PVAc/TiO2 Hybrid Nanofiber Mats

采用溶胶-凝胶法结合静电纺丝技术制备了聚醋酸乙烯酯(PVAc)/氧化钛(TiO2)杂化纳米纤维.通过使用扫描电子显微镜(SEM)和单纤维拉伸仪对不同条件下制备的杂化纳米纤维表面形貌和力学性能进行了表征和测试,探讨了有机无机杂化纳米纤维力学性能的影响因素.研究发现,随着TiO2溶胶含量的增加,纳米纤维表面珠状物减少,纳米纤维膜的断裂强度增大而断裂伸长率减小;随着滚筒转速的加快,纳米纤维毡的纤维取向有所改善,纳米纤维毡的断裂强度和断裂伸长率都有所增大;随着环境湿度的增加,纳米纤维毡的纤维之间粘结点增多,纳米纤维的断裂伸长率增大,断裂强度先增大后减小.
