Abstract

The effect of ultrasonic treatment of carbon nanotubes (CNTs) to restore their original degree of dispersibility has been investigated. A technologically accessible, convenient and effective method of «dry» ultrasonic activation without transferring nanofillers into suspension was proposed for CNT treatment. The efficiency of ultrasonic treatment was evaluated using a JEOL JSM-7800F LV scanning electron microscope. The change in the specific surface area of CNTs before and after ultrasonic treatment was evaluated on a NOVA touch LX2 specific surface analyzer. It is shown that this method increases the specific surface area of CNTs from 147 to 228 m2/g. The treated CNTs are used as a filler in the composition of rubber based on epichlorohydrin rubber Hydrin T6000. The physical-mechanical and wear-resistant properties of the modified rubbers as well as their frost resistance have been investigated.
