【摘要】 采用溶胶-凝胶法将二氧化硅（SiO₂）溶胶加入到聚醋酸乙烯酯（PVAc）的丙酮溶液中形成杂化纺丝液,测试了纺丝液的表面张力、粘度、电导率,再采用高压静电纺丝法制备了PVAc/SiO₂杂化纳米纤维膜。结果表明,SiO₂的加入改善了纳米纤维膜的形貌特征,膜的断裂强力增大,但断裂伸长率却有所降低,而膜的热稳定性也得到了提高。更多还原

【Abstract】 PVAc/SiO₂ hybrid spinning solution is prepared through sol-gel method and the surface tension,viscosity, conductivity of the solution are tested.Electrospin PVAc/Si02 hybrid nanofiber membrane through high-voltage electrospinning.The introduction of SiO₂ ameliorates the membrance surface characterization.The breaking strength and the thermogravimetry is increased along with the content of SiO₂,but the breaking elongation is decreased.更多还原
