# Preparation Methods and Properties of CNT/CF/G Carbon-Based Nano-Conductive Silicone Rubber
## 4 Conclusions  
In this study, the preparation method of conductive silicone rubber with carbon-based nanomaterials as fillers was studied and the properties of the conductive silicone rubbers were tested and characterized.  
1. Raman spectrum analysis showed that, compared to single-filler nano-conductive silicone rubbers, the interfacial adhesion and dispersibility of blended carbon-based nano-conductive silicone rubber were better.
2. Thermogravimetric analysis showed that the heat resistance of LSR/CNT/CF/G was better than that of LSR/CF, LSR/G, LSR/CNT, and pure LSR, and the initial decomposition temperature reached 476.8 \({}^{\circ}\)C.

* DSC analysis showed that the Tg of LSR/CNT/CF/G was similar to that of the single-filler nano-conductive silicone rubbers (around \(-50\)\({}^{\circ}\)C), which can meet the working environment of most varistors.
* XRD analysis showed that all the fillers were uniformly dispersed during ultrasonic dispersion and had strong interfacial forces.
* The tensile conductivity test showed that the effective tensile rates of LSR/CF, LSR/G, and LSR/CNT were 100%, 140%, and 300%, respectively, and the maximum effective tensile rate of LSR/CNT/CF/G was 520%. In addition, the resistance fluctuation range of LSR/CNT/CF/G was smaller than that of the single-filler nano-conductive silicone rubbers, which has good resistance and pressure sensitivity characteristics.  
In this paper, the preparation method of conductive silicone rubber by blending carbon fiber, graphene, and carbon nanotubes was preliminarily studied, but the research on the types and proportions of conductive silicone rubber fillers still has some limitations, and the follow-up research work can be carried out in the following directions:  
1. Enrich the types of conductive fillers, carry out surface treatment or modification treatment on the fillers, and improve the process according to the performance of different fillers.
* The fatigue strength and durability of conductive silicone rubber with mixed fillers were further investigated, which laid a foundation for the application of conductive silicone rubber in flexible sensors and other fields.
