摘要:

在外加电压的作用下,电致变色材料的光学性能(颜色、透光率等)能够可控制、可逆地变化,在节能减排领域有重要应用前景。随着相关研究的不断创新、深入和拓展,单一组分的电致变色材料因受到其自身结构和性能的限制,不能表现出人们所期望的电致变色性能,并且在结构和性能上不具有可设计和调控性,因而越来越无法满足实际应用的需求。与非复合电致变色材料相比较,复合型材料在这方面具有明显的优势,其优势体现在通过合理的材料设计,借助复合材料各组分的协调作用,充分激发各组分的优点,克服各自的缺点,可以获得结构和性能优异的电致变色材料。因此,近年来越来越多的研究聚焦于复合型电致变色材料。目前已开展研究的复合型电致变色材料的种类很多,根据复合组分是无机材料还是有机材料来对复合型电致变色材料分类的话主要可分为无机-无机复合、无机-有机复合和有机-有机复合3大类。相比有机电致变色材料,无机电致变色材料在材料成分控制、机械性能、光调制、使用稳定性、寿命等方面优势显著,因此,单一组分的和复合型的无机电致变色材料始终是本领域研究的重要方向。因此,本文致力于近年来无机-无机复合电致变色材料、器件和电解质的研究现状和未来的发展动态,对其研究进展、所存在的问题和发展趋势进行了归纳总结,为复合型电致变色材料的进一步研发和应用提供依据。

Abstract:

Under an external voltage, the optical properties (e.g. color, transmittance, etc.) of electrochromic materials can controllably and reversibly be changed, which has an important application prospects in the fields of energy conservation and emission reduction. With the continuous innovation and development of related research, the single-component electrochromic materials cannot show the expected electrochromic properties due to the limitations of their own structure and performance, and cannot be designed and regulated in their structure and performance, so it is increasingly unable to meet the needs of practical applications. Comparing with the non-composite electrochromic materials, the composite materials have obvious advantages in this aspect. Through the reasonable material design and with the coordination of each component, the core competitiveness of the composite materials is mainly represented by the electrochromic materials with excellent structure and performance can be obtained by stimulating the advantages and overcoming the disadvantages of each component. Therefore, more and more research focus on the composite electrochromic materials in recent years. At present many kinds of composite electrochromic materials have been researched, which mainly can be divided into three categories as inorganic-inorganic composite, organic-inorganic composite and organic-organic composite according to whether the composite components are inorganic or organic materials. Compared with the organic electrochromic materials, the inorganic electrochromic materials have significant advantages in material composition control, mechanical properties, optical modulation, service stability, life and other aspects. Therefore, either the single-component or the composite inorganic electrochromic materials have always been an important direction of research in this field. Hence, this paper devotes to the research status and development tendency of the inorganic-inorganic composite electrochromic materials, devices and electrolytes, including the research progress, the existing problems and the development trend. It will provide a basis for the further development and application of composite electrochromic materials.
