Abstract:

Polysulfonamide/carbon nanotubes/titanium dioxide (PSA/CNT/TiO2) nano composite spinning solutions with different CNT/TiO2 contents were prepared using the physical blending method. The corresponding fibers were extruded through a set of wet spinning unit, and composite membranes were prepared by the spin-coating method. The performances of the PSA/CNT/TiO2 nano fibers and membranes were investigated by means of SEM, FTIR and XRD etc. The influence of CNT and TiO2 on the mechanical properties, thermal stability, electrical conductivity and ultraviolet resistance of PSA nano composites was also analysed in this study. The experimental results showed that low contents of CNT/TiO2 can be distributed homogeneously in the PSA matrix; the molecular structure and chemical composition of PSA did not changed obviously; crystallisation in PSA occured at low CNT/TiO2 contents because it can act as a nucleation agent; the electrical conductivity and ultraviolet resistance of PSA nano composites can be improved significantly by blending CNT/TiO2 into the PSA matrix.
