Abstract

In this study, in-situ aluminum oxide-poly(dopamine)-silver (Al₂O₃-PDA-Ag) hybrid nanoparticles were synthesized using simple and eco-friendly approach. Al₂O₃ nanoparticles were first modified by PDA through mussel-inspired method, and Ag nanoparticles were then anchored on Al₂O₃-PDA nanoparticles surfaces through reduction of Ag⁺ by glucose. The as-obtained Al₂O₃-PDA-Ag nanoparticles were subsequently incorporated into natural rubber (NR) matrix to yield elastomer composites. The synergistic effect of Ag and Al₂O₃ nanoparticles resulted in high thermal conductivity of 10 vol% Al₂O₃-PDA-Ag/NR composite reaching up to 0.20 W/mK. This value was two-fold superior to that of pure NR (0.10 W/mK). In addition, Al₂O₃-PDA-Ag/NR composites showed excellent electromechanical and mechanical properties. Overall, the proposed method looks promising for future preparation of high-thermal-conductive dielectric materials.
