Significantly Enhanced Porosity of Silicone Rubber Nanocomposite Foams via Cross-Linking Structure Regulation and Heterogeneous Nucleation by CNTs for Promising Ultralow-k Dielectrics

Abstract: Ultralow-k materials with excellent thermal stability and good electrical insulation are urgently required taking into consideration the rapid development of 5G communication systems. Increasing the porosity of materials is the most effective way to reduce their dielectric constant. On this basis, with the help of cross-linking structure regulation and heterogeneous nucleation of CNTs, a polymethyl-vinyl siloxane (PMVS)/CNT foam with porosity up to 93.9% (density, 0.069 g/cm 3 ) was fabricated via supercritica… Show more

“…Amine-containing silicone resin (A-MQ) can enhance the tensile strength and elongation at the break of silicone rubber (ALSR) [19]. As SIR fillers, SiO 2 , alumina, silicon carbide, graphite oxide and carbon nanotubes can improve the mechanical properties and insulation of materials [20][21][22].…”
