Silicone Composites with CNT/Graphene Hybrid Fillers: A Review

Abstract

This review is dedicated to versatile silicone rubber composites based on carbon nanotube/graphene (CNT/G) hybrid fillers. Due to their unique mechanical, electrical, thermal, and biological properties, such composites have enormous potential for medical, environmental, and electronics applications. In the scope of this paper, we have explored CNT/graphene/silicone composites with a different morphology, analyzed the synergistic effect of hybrid fillers on various properties of silicone composites, and observed the existing approaches for the fabrication of hybrid composites with a seamless, assembled, and/or foamed structure. In conclusion, current challenges and future prospects for silicone composites based on CNTs and graphene have been thoroughly discussed.

Improvement the flame retardancy, thermal conductivity and mechanical properties of silicone rubber via silane coupling agent modified CNTs‐β‐FeOOH

“…Meanwhile, the low thermal conductivity of silicone rubber products also limits their applications. To solve these problems, researchers have tried to add certain amounts of graphene (GO), carbon nanotubes (CNTs), and boron nitride (BN) nanomaterials to improve their flame retardancy and thermal conductivity 5–7 . In recent years, these additives are often difficult to have high flame retardancy and thermal conductivity at the same time, and there are problems such as large addition 8 and decreased mechanical properties 9 .…”

“…To solve these problems, researchers have tried to add certain amounts of graphene (GO), carbon nanotubes (CNTs), and boron nitride (BN) nanomaterials to improve their flame retardancy and thermal conductivity. [5][6][7] In recent years, these additives are often difficult to have high flame retardancy and thermal conductivity at the same time, and there are problems such as large addition 8 and decreased mechanical properties. 9 Therefore, it is important to study efficient additives that make silicone rubber both flame retardant and thermally conductive.…”

Preparation of Carbon Nanotubes/Alumina Hybrid-Filled Phenolic Composite with Enhanced Wear Resistance

“…The use of a single filler in polymer matrix composites (PMCs) can no longer meet the demands of advanced PMC applications, which require multifunctional properties from a combination of two or more fillers and a hybrid system [ 13 , 14 , 15 ]. Attempts to combine several fillers or hybrid materials to form composites are not recent endeavours.…”

Special Issue: Synthesis and Characterization of Graphene-Based Hybrid Nanostructures

“…This Special Issue presents several of the latest advances in the synthesis and characterization of graphene-based hybrid materials and nanostructures, with relevance for the development of sodium-ion batteries [1], NO 2 sensors [2], periodic surface structures for cell growth [3], or the long-term protection of plasmonic silver nanoparticles (NPs) [4]. The fabrication approaches, current challenges and prospects for graphene-based silicone composites are also reviewed [5].…”

“…In a review by Barshutina et al [5], research from the last decade related to silicone rubber (or polydimethylsiloxane, PDMS) composites based on carbon nanotube/graphene (CNT/G) hybrid fillers is summarized. Adding CNT/G fillers to PDMS can result in highly conductive and stretchable materials with multiple potential applications in wearable electronics, medicine, or environment protection.…”
