Recently, the team of the Department of Polymer Science and Technology of Zhejiang University has developed a high thermal conductivity super-flexible graphene assembly film with a thermal conductivity of up to 2053 W/mK (Watt/mK), which is close to 40% of the thermal conductivity of an ideal single-layer graphene. A new record of thermal conductivity of the material; at the same time, the material is assembled from micro-pleated large graphene, which is ultra-flexible and can be folded 6,000 times and subjected to bending for 100,000 times.
