摘要
En 中文
Programmable thermal emissivity structures based on the bioinspired self-shape anisotropic materials were developed at macro-scale, and further studied theoretically at smaller scale. We study a novel concept, incorporating materials that are capable of transforming their shape via microstructural rearrangements under temperature stimuli, while avoiding the use of exotic shape memory materials or complex micro-mechanisms. Thus, programmed thermal emissivity behaviour of a surface is achievable. The self-shape structure reacts according to the temperature of the surrounding environment or the radiative heat flux. A surface which incorporates self-shape structures can be designed to quickly absorb radiative heat energy at low temperature levels, but is simultaneously capable of passively controlling its maximum temperature in order to prevent overheating. It resembles a game of colours, where two or more materials coexist with different values of thermal emissivity/absorptivity/reflectivity. The transformation of the structure conceals or reveals one of the materials, creating a surface with programmable - and therefore, variable-effective thermal emissivity. Variable thermal emissivity surfaces may be developed with a total hemispherical emissivity ratio (epsilon Eff _H/epsilon Eff_L) equal to 28.
