摘要
潜指纹显现技术在刑事案件侦查中有着非常重要的作用。而潜指纹显现技术对于材料有着较高的要求。文章首先综合评述了二氧化钛纳米材料常用的制备方法,包括均相沉淀法、水热法和溶胶凝胶法。然后,通过分析国内外的研究现状,总结了纯相TiO_(2)纳米材料与二氧化钛复合纳米材料在潜指纹显现技术中的应用与研究进展。最后,对TiO_(2)纳米材料在指纹显现技术应用中所存在的挑战进行了讨论,并对未来的研究方向进行了展望。
Latent fingerprint technology plays a very important role in criminal investigation.The latent fingerprint technology has higher requirements for materials.In this paper,the preparation methods of titanium dioxide nanomaterials are reviewed,including homogeneous precipitation,hydrothermal method and sol-gel method.Then,through the analysis of the research status at home and abroad,the application and research progress of pure phase TiO_(2)nanomaterials and TiO_(2)composite nanomaterials in latent fingerprint development technology were summarized.Finally,the challenges of the application of TiO_(2)nanomaterials in fingerprint display technology are discussed,and the future research directions are prospected.
