The reporter understands from hefei material science research institute of Chinese academy of sciences, the institute Tian Xingyou applied technology institute, a research and development team, in the recycling of nanometer photocatalytic materials and functional fabric coating research has made new progress. The research is published in the international journal cellulose.
In many contaminants, photocatalytic materials can effectively under the action of sunlight, degradation of pollutants, a variety of photocatalytic nanomaterials research has been used in the purification of the liquid or gaseous pollutants, is considered to be the most promising treatment approaches. But how to recycle this material is a key issue. Considering the structure characteristics of cotton fabrics is porous and hydrophilic, natural, the advantages of widely used group as load template, successfully constructed the nanometer photocatalytic coating fabric, implement the recycling of nanometer photocatalytic materials, and by alternating layers of assembly of nanometer photocatalytic materials, greatly improve the photocatalytic efficiency.
The coated fabric for liquid and gas pollutants are excellent photodegradation activity, under the simulated sunlight, all of the coated fabric can effectively degrade pollution gases such as formaldehyde, etc.) and liquid pollutants (such as rhodamine), shows the excellent degradation of gas and liquid pollutants, photocatalytic activity.
Is due to the excellent properties of the material, on the one hand, it is used in the recycled water purification of photocatalytic net fabric, especially suitable for urban black smelly water governance, decomposition of toxic organic compounds in water, deodorant, increase water, oxygen, restore self-purification ability, black ChouShui into water. On the other hand, the photocatalytic function make the curtain fabric, sofa cushion, carpet and other kinds of textiles, given its excellent degradation gas pollutants such as formaldehyde, anti-bacterial anti-uv features, such as the distinct effect to purify indoor air, in the field of home textiles or textiles, such as automotive interior show attractive prospect.
