Analysis of the structure of a conducting composite material based on butyl rubber for low-temperature composite electrical heaters

摘要

The structure of a conducting phase of a composite material based on butyl rubber with a dispersed technical carbon filler is analyzed by methods of optical microscopy and scanning and transmission electron microscopy. It is established that the employed production technology ensures homogeneous distribution of technical carbon particles of different structural levels over the rubber matrix. The morphology, phase structure, substructure of ingredients of conducting rubber in different states, and microstructure of the composite material, permitting us to draw a conclusion about electrical conductivity mechanisms, are determined.
