# Preparation Methods and Properties of CNT/CF/G Carbon-Based Nano-Conductive Silicone Rubber
## 1 Introduction
[11] filled three kinds of carbon fibers (CFs) with high-temperature vulcanized silicone rubber as the matrix and concluded that the percolation value of the conductive silicone rubber filled with CFs is related to the length of the CFs. [PERSON] et al. [12] successfully prepared silicone rubber composites with vertically oriented magnetic carbon fibers (o-MCF/SR) by casting the molding and filler orientation under a uniform magnetic field in a vacuum environment. The results show that the in-plane thermal conductivity of the o-MCF/SR composite exhibits an unusual power law increase with increasing MCF loading. [PERSON] et al. [13] assembled conductive silicone rubber layer by layer through graphene oxide and silicone rubber. When the number of layers is 30, the conductivity is 0.82 S/m. [PERSON] et al. [14] compounded silicone rubber with GO meteorological gel beads and modified materials (PCM) to prepare conductive and heat-dissipating silicone rubber. [PERSON] et al. [15] prepared FGO/HPDMS composites by mixing room-temperature vulcanized silicone rubber with FGO synthesized by treating divendiamide (HMDI) with GO, and the thermal conductivity and mechanical properties of the composites were obviously high. [PERSON] et al. [16] prepared conductive silicone rubber by mixing graphene nanomaterials (HGNS) with silicone rubber. Its microwave absorption rate is greater than that of other graphene composite materials. In the study of carbon nanotubes, [PERSON] et al. [17] grafted carbon black free radicals with modifiers and reacted them with CNTs to form carbon black CNT nano-fillers. [PERSON] et al. [18] prepared methyl vinyl silicone rubber-based composites filled with alumina (Al\({}_{2}\)O\({}_{3}\)) powder and carbon nanotubes by a conventional mechanical blending method. The results show that the thermal conductivity, Young's modulus, and hardness of the composite material are significantly improved by surface modification of Al\({}_{2}\)O\({}_{3}\) powder and adding a small amount of carbon nanotubes. [PERSON] et al. [19] introduced a kind of polydimethylsiloxane (PDMS)/multi-walled carbon nanotubes (CNT)/aligned nickel particles (Ni) composite material manufactured under a low magnetic field. The research shows that the compressive modulus of the composite material with 0.23 vol% CNT and 3.93 vol% Ni particles is 4.5 in the direction parallel to (X direction) and perpendicular to (Y direction) Ni particles arrangement, respectively. The above analysis shows that different conductive fillers and dispersion modes of conductive fillers have great influence on the properties of conductive silicone rubber, and conductive fillers such as carbon fiber, graphene, and carbon nanotubes can obviously improve the properties of conductive silicone rubber. At present, most of the literature has focused on research on the influence of two carbon-based fillers on the properties of conductive silicone rubber, and there is no literature on the preparation of conductive silicone rubber by blending three carbon-based fillers. Therefore, in this paper, carbon fiber, graphene, and carbon nanotubes were blended to prepare conductive silicone rubber, and the effects of blended fillers on the properties of conductive silicone rubber were studied, and the properties of conductive silicone rubber and pure silicone rubber with single filler were compared and analyzed.
