- Abstract
A computer simulation method was firstly used to determine the theoretical percolation threshold of the conductive filler/polymer composites. Firstly, the model by mixing two-phase graphene/ polyurethane composite in a certain proportions was set up, Secondly, effective medium theory is used for the computer simulation calculation to obtain the theoretical percolation threshold of the two-phase graphene/ polyurethane electrothermal material. The simulation results show that the electrothermal composite reaches the theoretical percolation in a graphene addition amount of 3.4 wt%. Based on the above simulation results, a graphene/polyurethane composite aqueous solution was successfully prepared by the solution blending method. Experimental results show that the electrothermal composite material reaches the percolation threshold by the use of 3.7 wt% graphene content. Finally, the mesh electrothermal material was prepared by coating the graphene/polyurethane slurry, and electrothermal temperature of the mesh is 50 °C at 24 V.
