Abstract Nowadays, different kinds of polymers, including ceramics, are electrospun into fibrous materials with different structures by electrospinning. Generally, the as-spun ceramic fibers are randomly oriented membranes and brittle without flexibility. Here, we report the fabrication of flexible SiO2 electrospun yarns using poly(vinyl alcohol) (PVA) as a template through a conjugate electrospinning process and calcination. It was found that the calcined as-spun fibers and yarns are obviously thinned with PVA component removal. Fourier transform infrared spectroscopy and energy-dispersive spectroscopy examinations suggested that the obtained yarn after calcination was SiO2 yarn. The SiO2 yarn showed good flexibility without cracking after 180° bending. The flexible ceramic yarn may have potential application in functional textiles.

通过共轭静电纺丝工艺制备柔性 SiO2 纳米纤维纱线

摘要 如今,包括陶瓷在内的不同种类的聚合物通过静电纺丝被电纺成不同结构的纤维材料。一般来说,初纺陶瓷纤维是随机取向的膜,脆而没有弹性。在这里,我们报告了使用聚乙烯醇 (PVA) 作为模板通过共轭静电纺丝工艺和煅烧制造柔性 SiO2 静电纺纱。发现经煅烧的初生纤维和纱线随着PVA组分的去除而明显变细。傅里叶变换红外光谱和能量色散光谱检测表明,煅烧后得到的纱线为SiO2纱线。SiO2 纱线显示出良好的柔韧性,180° 弯曲后不开裂。柔性陶瓷纱线可能在功能性纺织品中具有潜在应用。
