Core Viewpoint - The development of a reverse design AI model for thermal radiation metamaterials by a research team at Shanghai Jiao Tong University significantly enhances the efficiency of material design, enabling rapid generation of numerous candidate designs for various applications [1][2]. Group 1: AI Model Development - The AI model can filter through over 50,000 design combinations in just three months, a process that would take an astronomical amount of time using conventional methods [1]. - The model is inspired by the three-dimensional topology of biological structures and utilizes a novel "three-plane modeling method" to accurately describe three-dimensional structural units [1]. - A comprehensive database containing 57,110 sets of data has been established, linking materials, superstructures, and spectral performance [1]. Group 2: Practical Applications - The team validated the model's effectiveness by designing and experimentally verifying four types of thermal radiation metamaterials for specific applications, including flexible films, coatings, and patches [2]. - In outdoor tests, these metamaterials demonstrated excellent self-cooling effects, with single-band selective metamaterials showing surface temperatures 2.5°C and 5.3°C lower than broadband metamaterials and commercial white paint, respectively [2]. - The experimental results indicate the model's potential applications in building energy efficiency and mitigating urban heat island effects [2].
