Three-dimensional boron nitride network/polyvinyl alcohol composite hydrogel with solid-liquid interpenetrating heat conduction network for thermal management
文献摘要：
Polyvinyl alcohol hydrogels have been used in wearable devices due to their good flexibility and biocom-patibility.However,due to the low thermal conductivity(k)of pure hydrogel,its further application in high power devices is limited.To solve this problem,melamine sponge(MS)was used as the skeleton to wrap boron nitride nanosheets(BNNS)through repeated layering assembly,successfully preparing a three-dimensional(3D)boron nitride network(BNNS@MS),and PVA hydrogels were formed in the pores of the network.Due to the existence of the continuous phonon conduction network,the BNNS@MS/PVA exhibited an improved K.When the content of BNNS is about 6 wt.％,K of the hydrogel was increased to 1.12 W m-1 K-1,about two times higher than that of pure hydrogel.The solid heat conduction net-work and liquid convection network cooperate to achieve good thermal management ability.Combined with its high specific heat capacity,the composites have an important application prospect in the field of wearable flexible electronic thermal management.
