In this paper, polysulfonamide/carbon nanotube (PSA/CNT) composite solutions with different CNT contents were prepared using the physical blending method. Corresponding composite fibers were extruded and fabricated through a set of wet spinning units, and composite membranes were prepared by the spin-coating method. The PSA/CNT composite fibers and membranes were characterised by means of SEM, FTIR and XRD among others. The mechanical, thermal and electrical properties were also analysed in this study. The experimental results show that CNT at low contents can be distributed homogeneously in the PSA matrix. Furthermore the molecular structure and chemical composition of PSA does not undergo an obvious change. Crystallisation in the PSA can be promoted at low CNT contents because the nano-particles can act as a nucleation agent. Moreover the electrical conductivity of PSA can be improved significantly by the blending of CNT. Source

Aromatic polysulphonamides fibre, as a high-performance polymer fibre, was prepared by dry-jet wet spinning. The morphology and properties of polysulphonamides fibre along spinning line during dry-jet wet spinning process were investigated. From the development of mechanical and thermal property, it is shown that the fibre showed an improved stress, modulus and density along spinning line and the remarkable improvement was observed only as the fibre was hot stretched above its glass transition temperature (Tg). The property development of the fibre on spinning line is coordinated with the morphology and structure. When the fibre was drawn at the temperature lower than Tg, only the amorphous orientation was observed whereas the crystalline structure was formed as the fibre drawing temperature higher than Tg. The further optimisation of dry-jet wet spinning technology of polysulphonamides fibre could be supported by our results. © W. S. Maney & Son Ltd 2015. Source

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. © The Author(s) 2012 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Polysulfonamide/nano titanium dioxide (PSA/nano-TiO2) composite spinning solutions with various nano-TiO2 mass fractions were prepared using the solution blending method. The corresponding composite fibers were developed by wet-spinning technology and the composite membranes were prepared using the digital spin-coating technique. The properties of PSA/nano-TiO2 composite fibers and membranes were investigated by scanning electron microscope, Fourier transform infrared spectroscopy and X-ray diffraction, etc. The effects of nano-TiO2 and its mass fractions on the mechanical properties, thermal stability and ultraviolet resistance of PSA composites were also analyzed. The experimental results showed that nano-TiO2 with low mass fractions can be dispersed evenly in the PSA matrix; the blending of nano-TiO2 had no obvious influence on the molecular structure and the chemical composition of PSA fiber; the crystallization in PSA fiber was promoted at low nanoparticles mass fractions because it can act as a nucleation agent; the mechanical properties and the thermal stability of PSA/nano-TiO2 composites can be enhanced obviously by blending nano-TiO2 into PSA matrix. The ultraviolet resistance of PSA composites can be improved significantly with the increasing nano-TiO2 mass fractions and the 7 wt.% specimen showed the lowest UV transmittance. © 2013 Copyright The Textile Institute.
