摘要：

Nanocrystalline titanium dioxide has been prepared under ambient pressure and at temperatures close to or approaching room temperature using hydrolysis of titanium tetraisopropoxide in an acidic aqueous solution. A transparent thin layer of nanocrystalline titania has been produced on cotton textiles by a dip-pad -dry-cure process. These TiO2 coated cotton textiles possess significant photocatalytic self-cleaning properties, such as bactericidal activity, colorant stain decomposition and degradation of red wine and coffee stains. The UV absorption and tearing strength of the TiO2 coated cotton has also been studied. Self-cleaning cotton may find potential commercialization in the textile industry.
