Abstract:
In this work, hybrid fillers consist of modified silica (SiO 2 ) and multiwalled carbon nanotube (MWCNT) were used to improve the mechanical, dielectric, and thermal properties of fluorosilicone (FSR) composites via a direct mechanical mixing method. With the increase of CNT loading in SiO 2 /CNT hybrid loading ratio, the tensile properties, dielectric constant, electrical conductivity, and thermal properties all increase without a sharp sacrifice of flexibility. The dielectric constant of FSR‐S15/C5 achieved 7,370 @1 kHz, which is about four orders of the FSR‐S20, and the dielectric loss remains as low as 0.676 @1 kHz. Therefore, the linkage of SiO 2 and FSR chains not only enhances the interfacial interaction between the fillers and FSR matrix but also decreases the agglomeration of the fillers in matrix. What is more, modified SiO 2 and CNT were designed as the effective hybrid filler to improve the performance of the polymeric matrix through synergic effect.
