Structural design of multilayer thermally conductive nanofibrillated cellulose hybrid film with electrical insulating and antistatic property

Abstract

With the development of miniaturized and highly integrated of microelectronic products,it has become particularly important to fabricate a thermally conductive, electrically insulating and environment-friendly composite as thermal interface materials (TIMs) for heat dissipation. Here, we designed the structure of multilayer thermally conductive hybrid film based on Nanofibrillated Cellulose and fillers (Graphene and Boron nitride) using the vacuum-assisted layer-by-layer (VA-LBL) self-assembly technique. Fully unified the advantages of the thermally conductive three-layer electrically insulating film and antistatic film, the ordered five-layer thermally conductive film (7.04 W·m-1·K-1 with 8 wt% fillers) exhibits a comprehensive performance of electrically insulating and antistatic, which simultaneously has an excellent tensile strength (172 MPa). Therefore, it could be applied in TIMs for various thermal managements with diverse requirements safely and environmentally.
