Abstract
The effect of metallized carbon multilayer nanotubes (MWСNTs) on the thermal and electrophysical properties and structure of elastomer was studied. Ultrahigh frequency (UHF) synthesis technology was used to obtain metallized MWCNTs. The composite was obtained by mixing the compound and MWCNTs using a top-driven stirrer. The electro- and thermophysical properties of the composites obtained on the basis of 3 different types of elastomers - Silagerm 8020; 8030 and 8040 – were investigated.
It is noted that the Silagerm 8040 based composite has better performance, but there is a significant loss of elasticity, which is unacceptable in many process applications.
It is observed that the packing factor F for Silagerm 8040 and Silagerm 8030 has a close value, but its critical conductivity value is 2.5 and for Silagerm 8030 it is 2.3. At lower values of thermal and electrical conductivity, Silagerm 8020 retains a high level of flexibility.
The result of the work was the creation of a functional composite that has a self-regulating temperature effect when exposed to electrical voltage. Applications of functional composite with temperature self-regulation effect include electric heating technologies, where elastic materials resistant to corrosion and external temperature and mechanical effects are required.
