摘要

热成像仪根据斯特凡-玻尔兹曼定律检测来自表面的中红外辐射,绘制表面温度图,并潜在地揭示地下热活动。最近的发展为传统的基于相机的改进提供了另一种策略:热成像敏化剂(TIS)涂层,其发射率随着局部温度的升高而急剧增加,将微小的热变化放大为高对比度信号。现有的TIS结构是纳米固体膜,在制造复杂性方面面临重大挑战。在这里,我们提出了一种溶液处理的液体形式的TIS,称为温度适应性辐射涂料(TARP),以解决这些限制。TARP大幅降低了制造成本,可扩展到大面积,适用于曲面,并延长了工作温度范围,同时保持了温度放大的功能。TARP的应用将小温度对比度提高了3倍以上,大大改善了环境热成像,使其能够更广泛地应用于电子元件的结构缺陷和热点检测。

Solution-Processed Temperature-Adaptive Radiative Paint as a Thermal Imaging Sensitizer.
Thermography detects mid-infrared radiation from surfaces based on the Stefan-Boltzmann law, mapping surface temperatures and potentially revealing subsurface thermal activity. Recent developments offer an alternative strategy to traditional camera-based improvements: a thermal imaging sensitizer (TIS) coating whose emissivity increases sharply with local temperature, amplifying small thermal variations into high-contrast signals. Existing TIS structures are nanofabricated solid membranes and face significant challenges in fabrication complexity. Here, we present a solution-processed, liquid form of TIS, termed temperature-adaptive radiative paint (TARP), to address these limitations. TARP offers drastically reduced fabrication costs, scalability to large areas, applicability to curved surfaces, and an extended operating temperature range, while maintaining the function of temperature amplification. Application of TARP enhances small temperature contrast by more than 3 times, substantially improving ambient thermography and enabling broader applications such as detection of structural defects and hot spots in electronic components.
