摘要
为了提高棉织物的疏水性能,文章基于仿生学原理在织物表面构筑了TiO_2纳米管的多孔网络结构,赋予了棉织物对多重水溶液的超疏液功能和自清洁功能。首先以TiO_2纳米颗粒为原料制备了TiO_2纳米管,随后将全氟辛基三乙氧基硅烷接枝到TiO_2纳米管上,最后通过涂覆法将氟化TiO_2纳米管整理到了棉织物表面。接触角测试结果表明,涂层后棉织物具有良好的超疏液性能,自清洁与抗紫外性能测试亦证明了基于TiO_2纳米管网状涂层的棉织物具有良好的自清洁和抗紫外性能。
To endow the cotton fabric with the superhydrophobic and self-cleaning properties, a porous TiO_2 nanotube network is constructed on its surface based on the bionics principle. TiO_2 nanotubes were prepared by TiO_2 nanoparticles as its raw material. Subsequently, perfluorooctyl triethoxy silane was grafted onto the TiO_2 nanotubes, and finally the fluorinated TiO_2 nanotubes were coated to the surface of the cotton fabric.According to the contact angle test, the results indicated that coated cotton fabric has good superhydrophobic properties. And self-cleaning and UV resistance tests have also demonstrated good self-cleaning and UV resistance based on TiO_2 nanotube mesh coating.
