柔性高强度二氧化硅纳米无机纤维膜
技术领域
本发明涉及一种柔性高强度二氧化硅纳米无机纤维膜，属于化学纤维技术领域。
背景技术
纳米纤维膜又称为纳米膜，纳米膜分为颗粒膜与致密膜。颗粒膜是纳米颗粒粘在一起，中间有极为细小的间隙的薄膜。致密膜指膜层致密但晶粒尺寸为纳米级的薄膜。可用于：气体催化（如汽车尾气处理）材料；过滤器材料；高密度磁记录材料；光敏材料；平面显示器材料；超导材料等。
静电纺丝是一种简便易行、可以直接从聚合物及复合材料制备连续纤维的方法,其制备的纳米纤维薄膜通常是以无纺布形式存在的。静电纺丝技术具有一些突出的优点:设备和实验成本较低,纤维产率较高,制备出的纤维比表面积比较大(纤维直径在几十纳米到几个微米的范围内),并且适用于许多不同种类的材料。这些优点使静电纺丝纳米纤维薄膜在许多领域具有广泛的潜在应用。
