把TiO_2作成纤维国际上已有报道,所得纤维直径分别为1～2μm,且处理步骤繁杂.用激光化学法一步获得直径0.1μm以下的TiO_2纤维,尚未见报道.由于脉冲激光能产生局部的快速加热和冷却,即使引发的是热化学反应,也仍具有与一般加热反应不同的特征.我们用激光法所得TiO_2的初步研究已显示它与用通常方法所得TiO_2有显著差异.
It has been reported in the world that TiO 2 fiber is obtained, the diameter of the obtained fiber is 1 ~ 2μm, and the processing steps are complicated.It has not been reported that the TiO_2 fiber with the diameter of 0.1μm or less in one step by laser chemical method has not been reported.Because pulsed laser can produce local fast Heating and cooling, even with the initiation of thermochemical reactions, still have characteristics that are different from those of the general heating reaction.Preliminary studies of the TiO 2 obtained by our laser method have shown a significant difference from the TiO 2 obtained by the usual methods.
