本发明公开了一种间位芳纶纳米蛛网纤维膜的制备方法。所述的制备方法为:将间位芳纶溶解于卤盐和有机溶剂混合,配制成的离子液体溶剂体系中,得到间位芳纶电纺原料;将上述间位芳纶电纺原料加入到静电纺丝装置中进行静电纺丝,制得间位芳纶纳米蛛网纤维膜。本发明制备方法过程简单,制得的间位芳纶纳米蛛网纤维膜与普通静电纺纤维膜纤维相比,其纤维直径更小、比表面积更大、纤维膜孔径更小、孔隙率更高,同时具有间位芳纶突出的耐高温性、防火性和良好的尺寸稳定性,可广泛应用于高温过滤、防护、电池隔离膜、传感和生物医学等领域。专利申请号:CN201210169182.6公开号:CN102704028A申请人:东华大学
The invention discloses a method for preparing meta-aramid nano-cobweb fiber membrane. The preparation method comprises the following steps: a meta-aramid is dissolved in a mixture of a halogen salt and an organic solvent to prepare a meta-aramid electrospinning raw material; the meta-aramid electrospinning raw material is added to Electrospinning electrostatic electrospinning device, meta-aramid nano-spider fiber membrane obtained. Compared with the ordinary electrospun fiber membrane, the meta-aramid nano-cobweb membrane produced by the method has the advantages of simple process, smaller fiber diameter, larger specific surface area, smaller fiber membrane pore size and higher porosity, At the same time have a meta-aramid outstanding high temperature resistance, fire resistance and good dimensional stability, can be widely used in high temperature filtration, protection, battery isolation film, sensing and biomedical fields.
