BiOBrxI1-x光催化复合芳纶织物的性能研究
Property research of composite aramid fabric modified by BiOBrxI1-x photocatalyst
摘要
Abstract
In order to develop photocatalytic composite aramid fabric,the ion layer by layer adsorption and reaction method were used to regulate the molar ratio of potassium bromide and potassium iodide in the growth solution.Bismuth oxyhalide solid solution nanosheets were assembled in situ on the surface of alkali treated aramid 1313 fabric(MAF)fibers,then BiOBrxI1-x-MAF fabric were prepared.The structure and morphology,surface color,light resistance,photocatalytic performance and hydrophobicity were systematically characterized and analyzed.The results showed that the photocatalyst BiOBrxI1-x on the surface of aramid fibers exists in the form of an array of bismuth oxyhalide solid solution nanosheets.As the iodine ion content in the solid solution increased,the apparent color of the fabric gradually changed from white to yellow,and ultimately to red.The loading of bismuth oxyhalide solid solution significantly improved the light aging phenomenon of aramid fabric,endowing aramid fabric with photocatalytic degradation performance of organic pollutants.The uniform growth of bismuth oxyhalide nanosheets on the fiber surface and water-based stains formed a Wenzel and Cassie transition state model,achieving hydrophobic self-cleaning effect.It is believed that the construction of photocatalytic aramid fabrics provides new ideas for the development of multifunctional aramid and helps to broaden the application scope of aramid.关键词
