| 摘 要： | 采用原位复合溶胶-凝胶法配制复合纺丝液,通过高压静电纺丝制备出PVDF/SiO2复合纳米纤维膜。通过SEM表征了PVDF/SiO2复合纳米纤维的纺丝效果,同时对比了使用两种方法添加6%SiO2制得的PVDF静电纺复合纳米纤维的表面形貌及力学性能。研究了原位纳米SiO2的加入对膜的孔径变化以及力学性能的影响。结果表明,原位硅的加入,增加了纤维的表面粗糙度;降低了复合膜内的微孔直径,并使得微孔直径分布更加集中;改善了膜的力学性能,添加6%原位硅时效果最佳。在SiO2含量为6%时,与直接添加相比,原位复合法制得的复合膜力学性能更佳。

| Abstract: | Composite spinning solution of PVDF/SiO2 prepared by in-situ composite sol-gel,and the composite nanofibers fabricated by electrospinning.The spinning effect of PVDF/SiO2 composite nanofiber were investigated by SEM,simultaneously the fiber surface morphology and mechanical properties of PVDF/SiO2 composite nanofiber made using two adding 6% silica methods was compared.The results showed that adding in-situ silicon increased fiber surface roughness,reduced the pore diameter of composite nanofiber membrane a... |
