Abstract

Nanotubes with multi-walled structures have the ability of changing the characterization of poly (Silicone Rubber) nanocomposites. In this way, silicone rubber/multiwalled carbon nanotubes (SR/MWCNTs) nanocomposite is achieved by reaction with multifunctional. A new design of SR/MWCNT nanocomposites was developed as a result of experiments to clarify the advantages of filling the MWCNTs with different patterns within the dielectrics. As part of this work, silicone rubber/multiwalled carbon nanotube nanocomposites and room temperature vulcanization (RTV) methods were used to fabricate piezoelectric sensors. The analysis of the frequency response of SR/MWCNT nanocomposites has been conducted under variable thermal conditions (20–40°C). This study succeeded in applying poly (Silicon Rubber) nanocomposites as piezoelectric sensors by exhibiting new electrical characteristics (resistance, capacitance, real and imaginary impedance) under various thermal conditions based on certain types and concentrations of MWCNTs.

用于热条件下压电传感器的 SR/MWCNTs 纳米复合材料的制备和电气特性分析

摘要具有多壁结构的纳米管能够改变聚（硅橡胶）纳米复合材料的特性。因此，硅橡胶/多壁碳纳米管（SR/MWCNTs）纳米复合材料通过多功能反应得以实现。通过实验，我们开发了一种新的 SR/MWCNT 纳米复合材料设计，以阐明在电介质中填充不同图案的 MWCNTs 的优势。作为这项工作的一部分，硅橡胶/多壁碳纳米管纳米复合材料和室温硫化（RTV）方法被用于制造压电传感器。在不同的热条件（20-40°C）下，对硅橡胶/多壁碳纳米管纳米复合材料的频率响应进行了分析。这项研究成功地将聚（硅橡胶）纳米复合材料应用于压电传感器，根据特定类型和浓度的 MWCNT，在各种热条件下显示出新的电气特性（电阻、电容、实阻抗和虚阻抗）。

期刊介绍： Russian Journal of Nondestructive Testing, a translation of Defectoskopiya, is a publication of the Russian Academy of Sciences. This publication offers current Russian research on the theory and technology of nondestructive testing of materials and components. It describes laboratory and industrial investigations of devices and instrumentation and provides reviews of new equipment developed for series manufacture. Articles cover all physical methods of nondestructive testing, including magnetic and electrical; ultrasonic; X-ray and Y-ray; capillary; liquid (color luminescence), and radio (for materials of low conductivity).
