Inspired by the hollow skeletal structure of bird bones, which optimizes oxygen storage and respiratory efficiency, researchers from the University of Science and Technology Beijing developed a 3D hollow diamond-enhanced PEG composite PCM. The composite, HDF/PEG, leverages the excellent thermal conductivity of diamond and the advantages of a 3D interconnected structure to create a high-conductivity transport network. The study details the fabrication process of the HDF skeleton using microwave plasma chemical vapor deposition (CVD), laser perforation, and acid immersion, followed by the encapsulation of PEG2000 within the HDF structure.
