摘　　要：以廉价无机盐为原料，纳米碳黑作为模板，采用模板法制备了小粒径、窄分布的无团聚纳米金红石TiO2粉体，并用激光粒度分析仪、X射线衍射仅、透射电镜（TEM）、紫外分光光度计等手段对纳米TiO2结构性能进行了表征，研究了纳米TiO2粉体对纤维素织物的抗紫外线整理效果，结果表明：采用模板法所制备的TiO2粉体粒度小（17．56nm）、分布均匀、分散稳定性好；平均粒径为30nm左右的纳米TiO2整理后的纤维素织物抗紫外线效果明显提高。模板碳黑在前驱体的制备以及热处理转相过程中发挥了良好的阻团聚作用。A novel template method is described for the production of rutile titania nanoparticle by using nano-carbon as template and cheap inorganic titanium chloride as raw material. The microstructure and property of the as-synthesized nanoparticle were characterized respectively by laser granularity instrument, TEM, X-ray diffraction and UV spectrophotometer. The anti-ultraviolet property of the different concentration titanium oxide on cellulose fiber were studied. The results show the as-synthesized titania nanoparticle has rutile structure and external diameter of 17.56nm without obvious agglomeration. The anti-ultraviolet effect of cellulose fiber was improved remarkably while finished using titania nanoparticle of 30nm diameter. The template carbon black exerts steric stabilization function during the preparation of precursor and calcining and holds back the growth and conglomeration of nanometer powder effectively.
