| Popis: | Multi-walled carbon nanotubes were functionalized using a sequence of treatments which included grafting of carboxyl groups, converting them to acyl chloride groups with thionyl chloride followed by reactions with amine or ammonia. Another treatment procedure consisted of chlorination in the gas phase followed by reaction with ethylenediamine or ammonia. In both cases, the samples were heated conventionally or using a microwave oven. The influence of treatment method on the carbon nanotube properties is presented. Amine-functionalized carbon nanotubes were examined for their application as a nanofiller in epoxy resins and the electrical conductivity of the obtained polymer composites was investigated. |
