摘要：

A composite film with gradient structure constructed through infiltrating liquid metal (LM)/Polyvinyl alcohol (PVA) solution into a boron nitride nanosheet/silk fibroin (BNNS/SF) electrospinning film was developed. The gravity driven settling and PVA welding give rise to the gradient distribution of LM, and the LM/BNNS/SF composite film was obtained following the mold pressing. Benefitting from the LM, the LM/BNNS/SF composite film exhibits a highest through-plane thermal conductivity (TC) about 3.24 W/m center dot K and a highest in-plane TC about 12.53 W/m center dot K, together with outstanding electromagnetic shielding efficiency, reaching to 75 dB in X band. Moreover, the LM/BNNS/SF composite film also exhibits good surface insulativity, exhibiting great potential in electronic packaging material field.
