Functionalized Aluminum Nitride for Improving Hydrolysis Resistances of Highly Thermally Conductive Polysiloxane Composites
Highlights Copolymer of divinylphenyl-acryloyl chloride copolymers (PDVB-co-PACl) is designed and synthesized to graft on the surface of aluminum nitride (AlN) to improve its hydrolysis resistance. AlN fillers functionalized by PDVB-co-PACl with the molecular weight of 5100 g mol-1 exhibits the high...

| description | Highlights Copolymer of divinylphenyl-acryloyl chloride copolymers (PDVB-co-PACl) is designed and synthesized to graft on the surface of aluminum nitride (AlN) to improve its hydrolysis resistance. AlN fillers functionalized by PDVB-co-PACl with the molecular weight of 5100 g mol-1 exhibits the highest hydrolysis resistance and the lowest interfacial thermal resistance. When the mass fraction of AlN@PDVB-co-PACl is 75 wt% and the grafting density of PDVB-co-PACl is 0.8 wt%, the λ for AlN@PDVB-co-PACl/PMHS composites is 1.14 W m-1 K-1 and maintains 99.1% after soaking in 90 °C deionized water for 80 h. |
