Studies on high performance rubber composites by incorporating titanium dioxide particles with different surface area and particle size

Abstract

In this work, we incorporate titanium dioxide (TiO2) particles as fillers into room temperature vulcanized silicone rubber (RTV-SR) and fabricated the RTV-SR/TiO2 composites. Herein, the effect of various surface areas of TiO2 particles on the mechanical properties of RTV-SR/TiO2 composites was investigated. The particle size of different types of TiO2 particles (147 nm, 34 nm, and 29 nm) was measured by using scanning electron microscopy (SEM), whereas the Brunauer–Emmett–Teller (BET) surface area was measured through adsorption-desorption isotherms as 3, 50, and 145 m2/g, respectively. TiO2 particles reinforced RTV-SR composites were prepared by solution mixing method. TiO2 particles with smaller particle sizes and high BET surface area exhibited higher mechanical properties. The compressive moduli were obtained as 2.2 MPa for a virgin sample and increased to 2.6 MPa, 2.8 MPa and 3.24 MPa for 3, 50, and 145 m2/g samples respectively at 6 phr filler loading. Similarly, the fracture strain of the composite was 117% for a virgin sample and changed to 94%, 130%, and 205% for 3, 50, and 145 m2/g samples, respectively, at 8 phr filler loading. The surface area and particle size of the fillers showed significant effect on mechanical properties of the composites, but no significant effect was observed on the energy harvesting values of RTV-SR/TiO2 composites.

Modulating the Configurations of “Gel-Type” Soft Silicone Rubber for Electro-Mechanical Energy Generation Behavior in Wearable Electronics

“…The electro-mechanical energy generation under mechanical strain or human motion is a hot topic of research recently and is thus explored experimentally in this work [ 54 ]. The sensitivity of the electro-active composite materials based on “gel-type” soft SR often exhibits piezo-electric behavior and often became a source of electricity [ 55 ]. Thus, these composites became self-powdered wearable electronic devices type for commercial applications such as sensitivity towards mechanical motions and useful for health monitoring such as heartbeat or e-skin [ 56 , 57 ].…”

Robust performance for composites using silicone rubber with different prospects for wearable electronics

“…The fabrication of the composite used in a wearable device developed in the present work was optimized in previous studies 38 . The process involved in four steps and summarized below: First, the molds used in making composite samples were sprayed with the mold‐releasing agent and left for 2–3 h for drying.…”

Synthesis and applications of carbon porous nano-materials for environmental remediation

“…Carbon-based nano-materials have been satisfactorily identified with superior implementation and tailorable effects in the adequate degradation of contaminants (Hussain et al, 2021;Kumar Mishra et al, 2021). Wherein carbon nanofibers (CNFs) have exhibited a high possibility of eradicating contaminants from water owing to their benefits of easy synthesis, chemical resilience, and economic and environmental friendliness (Kumar et al, 2022;Sudhaik et al, 2022).…”
