Principles of Radiation Cooling and Inspirational Organisms and Materials in Nature for Biomimetic Radiation Cooling
This study firstly starts from the basic principle of radiation cooling, and introduces the radiation cooling characteristics of organisms in nature. Different organisms realize the regulation of radiation refrigeration through their materials, microstructures, and behaviors, which has brought inspiration to human exploration of new radiation refrigeration materials and devices. In addition, the biological radiation cooling mechanism is summarized, the optimization method of biological structure is summarized, and the current research progress of bionic radiation cooling is introduced, and the research direction, application prospect and material preparation method of bionic radiation cooling are prospected. High-power and intelligent radiation refrigeration materials and devices are an important development direction for bionic radiation refrigeration in the future. The integration of advanced micro-nano processing technology will enable bionic radiation refrigeration to have a broader market and application in the future.
Biomimetic radiation refrigeration material and its preparation
In the future, bionic radiative cooling should develop in the direction of simplicity, high power, controllability, low cost, and large-scale manufacturing. The important reasons that currently limit the large-scale application of radiation cooling materials and devices are that the radiation cooling power is low, the cooling speed is slow, and the cooling effect is not ideal. Thinking from the perspective of biology, in nature, many organisms have evolved a very perfect thermoregulation mechanism. People get inspiration from these structures and mechanisms, imitate the biological structure, simplify and optimize the biological structure through theoretical simulation, and prepare excellent performance. radiative cooling materials. At the same time, more sophisticated biophotothermal microstructures are integrated into the design of the same thermal control function system to complement each other, expand the wavelength range of bionic radiation cooling materials and devices, and achieve better radiation cooling effects. Combined with application scenarios, such as clothing materials, good air permeability, skin-friendly and color adjustability are also required. To this end, it is necessary to integrate radiative cooling performance with other properties, design multiple composite structures, and be intelligent according to different application scenarios. Tuning the radiative cooling properties of materials. In addition, with the emergence of various advanced material manufacturing processes, the integration of advanced micro-nano processing technology into the preparation of biomimetic radiation refrigeration materials can achieve high-efficiency and low-cost large-scale manufacturing of biomimetic radiation refrigeration materials. Biomimetic radiation refrigeration is a multidisciplinary and innovative research field, which requires the joint efforts of research teams in various fields to promote its development and application, and the future can be expected.
