Recently, the team of high-polymer professors at Zhejiang University developed a high-conductivity ultra-flexible graphene membrane with a thermal conductivity of up to 2053W/mK, which is close to 40 % of the ideal single-layer graphene thermal conductivity, creating a macroscopic material New record of thermal conductivity; At the same time, the material is assembled from a micropleated large graphene, which is super flexible and can be repeatedly folded 6,000 times and subjected to bending 100,000 times.
