Study on the thermal behaviour of polysulfonamide/ multi-wall carbon nanotube composites

Polysulfonamide polymers are defined by their heat-resistant ability subjected to a high temperature. The thermal behaviour of polysulfonamide polymers can be tailored by using the polymer as a matrix of multiphase composites. Multi-wall carbon nanotubes were blended with polysulfonamide polymers and the corresponding fibers were prepared by wet spinning. In the present paper, we have presented thermal behaviour of functionalized multi-wall carbon nanotube-reinforced polysulfonamide polymer by thermal gravimetric analysis and presented a heat conducting model to explain its thermal conductive behaviour. The experimental results showed that the thermal behaviour of developed multi-wall carbon nanotube-reinforced polysulfonamide composites were influenced by multi-wall carbon nanotube weight fraction in the polymer matrix. Multi-wall carbon nanotube in the polysulfonamide does have much influence on the thermal decomposition ratio of the polysulfonamide/multi-wall carbon nanotube composites.
