Nano TiO2-doped anti-ultraviolet para-aramid nano paper and preparation method thereof

摘要

The disclosure discloses nano TiO2-doped anti-ultraviolet para-aramid nano paper and a preparation method thereof. First, nano TiO2 is selected as an ultraviolet absorbent which has a good absorption effect on ultraviolet rays, and the anti-ultraviolet characteristic of aramid paper-based material can be well improved through addition of nano TiO2. Second, macroscopic para-aramid fiber is dissolved under the action of a DMSO/KOH system, and the surface of the prepared aramid nano fiber is rich in C═O and N—H. This method is simple in process and does not harm the fiber itself, and can effectively improve the mechanical strength, interface binding performance and processability of a base material. The nano TiO2-doped anti-ultraviolet para-aramid nano paper prepared by the disclosure is simple in preparation process, excellent in material property.
