Termites are known as outstanding builders in nature that can create multifunctional mounds and even develop adequate ventilation and temperature regulation systems to conquer severe environmental conditions. Notably, based on our observations from micro-CT and SEM, the termite nest possesses a three-dimensional continuous cellular structure with a high surface-to-volume ratio which shares similar features with the triply periodic minimal surface (TPMS) structure. Inspired by the structure of termite nest, we design a series of modified cellular structures with gradient periodicity and investigate the heat transfer and sound penetration properties with varying structural parameters. By applying 3D printing technology and finite element simulation, compressive mechanical properties, heat distribution and sound attenuation behaviors are further evaluated and discussed. Moreover, we can optimize these properties to develop multifunctional cellular structures based on the analytical results. Consequently, the optimized structure inspired by the termite nest can further broaden potential applications.
