光热转换涂层是太阳能光热利用的核心关键之一，对于主动设计高效太阳能集热器具有重要的指导意义。金属—介质复合型涂层是最常用的一类光热转换涂层，但掺杂金属纳米颗粒的高温扩散性和化学活性导致该类涂层的耐高温和抗环境腐蚀能力较差。本课题拟将具有优异物理和化学性能的类富勒烯碳应用于光热转换涂层，从光热转换涂层的设计原理出发，选择能与碳形成稳定碳化物的Ⅳ－Ⅶ族过渡金属（Ti、C、W、Zr等）作掺杂元素，以类富勒烯碳为非晶基质，通过纳米复合，设计、制备一种基于类富勒烯碳的新型光热转换涂层－纳米晶金属碳化物/类富勒烯碳复合光热转换涂层，克服传统金属掺杂所带来的缺点，显著提高涂层的耐高温和抗腐蚀性能，满足实际应用需求。从宏观到微观角度认知涂层内在结构对其光吸收、耐高温和抗腐蚀性能的影响，建立类富勒烯碳基光热转换涂层的制备工艺－结构－性能的关系模型，为拓展其在太阳能光热领域的应用提供理论依据和实践经验。

Photo-thermal conversion coating is one of the key technologies in solar energy thermal utilization, it has an important guiding significance for designing the high efficiency solar collector. Metal-dielectric composite (cerment) coating is the most commonly used type of photo-thermal conversion coating, but it also has the disadvantage of poor high-temperature resistance and corrosion resistance due to its chemical activity and metal nanoparticles diffusion in it. Therefore, to solve this issue, the project is aimed at studying and employing the fullerene-like structured carbon materials with outstanding physical and chemical properties into the application of solar photo-thermal field. According to the design principle of solar-thermal conversion coating and considering the advantages such as high-melting, high hardness and chemical stability of metal carbide, we choose Ⅳ-Ⅶ family of transition metal (Ti, Cr, W, Zr, etc) as the doping elements and the fullerene-like carbon as amorphous matrix in developing a new photo-thermal conversion coating-nanocrystalline metal carbide/fullerene-like carbon composite photo-thermal conversion coating, which possesses high stability, long-life and outstanding weather resistance is also implemented to drastically improve the high-temperature resistance and corrosion resistance and to meet the demand of practical application. Studying how the inner micro-structure effect optical absorption properties, corrosion resistance and high-temperature resistance of the coating, which has significant meaning both industrially and theoretically for the fullerene-like carbon film adhibition in solar photo-thermal field. Establishing the relationship mode of fabricating technology-structure-performance of fullerene-like carbon based photo-thermal conversion coating. This project will provide more practical and theoretical basis to the fullerene-like carbon films expand adhibition in solar thermal applicition.
