摘要
本文主要阐述了纳米WO3气致变色材料的溶胶-凝胶制备方法、气致变色机理及其应用的研究新进展,重点评述了溶胶-凝胶法中各种制备条件诸如掺杂、模板剂、溶剂、热处理温度等对这种材料的结构和性能的影响,最后展望了纳米WO3气致变色材料的研究和应用前景。我们认为,在未来的溶胶-凝胶法制备纳米WO3气致变色材料领域,如何进行最优化的掺杂设计和选择高效模板剂、如何降低气体检测温度以及气致变色机理等将是该项研究的重点。
The recent progress in sol-gel preparation of nano WO3 materials, their gasochromic mechanism and applications are expatiated in this review. The influence of sol-gel conditions such as hybrid, templatig agent, solvent and calcination temperature, etc. on the structures and properties of such materials, is comment with emphasis. Finally, the prospect of the research and application of nano WO3 gasochromic materials is also forseen. We believe that the key points of the future study on nano WO3 materials prepared by sol-gel process will be how to optimize the design and selection of efficient doping materials and templates, and how to reduce the temperature of gas detection and find the real gasochromie mechanism.
