Abstract The rapid advancement of energy, electronic, and microelectronic technology has resulted in a surge interest the study functional composites. One current hotspots this field is exploitation polymer composites with excellent thermal conductivity great stability. Based upon composition adhesion proteins shellfish, dopamine chemistry was applied to non‐chemical surface modification chemically inert fillers by generating polydopamine (PDA) films on their surfaces. In paper, we utilized...
