Enhanced properties of silicone rubber dielectric composites by incorporation of novel TiO2@Tl nanoparticles
It is necessary for silicone rubber dielectric composite to improve filler dispersion and enhance energy storage performance. In this study, a novel strategy is developed to overcome the limitations associated with the poor dispersion of polar fillers in non-polar silicone rubber. This study anchors titanium dioxide (TiO2) nanoparticles onto talc (Tl) nanoplatelets by dehydration reaction of hydroxyl groups on filler surface to synthesize a novel filler TiO2@Tl. TiO2@Tl combines the advantages of TiO2 and Tl, and reduces the number of polar hydroxyl groups to weaken its polarity, which significantly enhances the compatibility with methyl vinyl silicone rubber (MVSR). Compared to directly adding two fillers TiO2 and Tl into MVSR (TiO2-Tl/MVSR), TiO2@Tl/MVSR composite exhibits the more uniform filler dispersion and better overall performance at equivalent filler levels. 10 wt%TiO2@Tl/MVSR composite exhibits the highest energy storage density of 95.55 kJ/m3, representing a 42.2 % increase compared to pure MVSR (67.15 kJ/m3) and a 13.2 % increase compared to 5 wt%TiO2-5wt%Tl/MVSR (84.39 kJ/m3).
期刊介绍:
Composites Communications (Compos. Commun.) is a peer-reviewed journal publishing short communications and letters on the latest advances in composites science and technology. With a rapid review and publication process, its goal is to disseminate new knowledge promptly within the composites community. The journal welcomes manuscripts presenting creative concepts and new findings in design, state-of-the-art approaches in processing, synthesis, characterization, and mechanics modeling. In addition to traditional fiber-/particulate-reinforced engineering composites, it encourages submissions on composites with exceptional physical, mechanical, and fracture properties, as well as those with unique functions and significant application potential. This includes biomimetic and bio-inspired composites for biomedical applications, functional nano-composites for thermal management and energy applications, and composites designed for extreme service environments.
