  • preparation of vertically aligned carbon nanotube polyaniline composite membranes and the Flash Welding effect on their supercapacitor properties
    RSC Advances, 2016
    Co-Authors: Jinrui Zhang, Zhoujing Li, Xia Wang, Xiaoyan Li, Jie Ding
    Abstract:

    A vertically aligned carbon nanotube (CNT)/polyaniline (PANi) composite membrane was prepared by a simple filtration and electrical synergy method. Considering the high alternating electric field and strong shear forces during suction, vertically aligned single-walled nanotubes (SWNTs) were found in the SWNT/PANi composite membrane. Scanning electron microscopy and polarised Raman scattering demonstrated that the degree of alignment of the SWNTs improved with increasing electric voltage. Nanoindentation technology indicated that the modulus and hardness of the SWNT/PANi composite membrane increased in the vertically aligned CNTs. Owing to the special photo-thermal property of the PANi nanofibres, a SWNT/PANi composite film with an improved crosslinking structure and strong π–π interactions between PANi and SWNTs was obtained by intensity Flash irradiation. The surface density, water contact angle and thermal stability of the composite film increased after Flash Welding. Nanoindentation technology indicated that the SWNT/PANi composite film significantly increased in modulus and hardness after Flash Welding. The SWNT/PANi film fabricated by filtration and electrical synergy method also demonstrated an improved specific capacitance of 146.0 F g−1 in 6 M KOH at 0.5 A g−1 after Flash Welding while maintaining good cycling stability. The prepared SWNT/PANi composite film is suitable for portable and wearable electronic applications.

  • Preparation of MWNTs/polyaniline composite membranes by filtration and Flash Welding method
    2014
    Co-Authors: Xiaoyan Li, Jie Ding, Xia Wang, Deng-guang Yu, Yaozu Liao
    Abstract:

    This paper reports the fabrication of multiwalled carbon nanotubes (MWNTs)/polyaniline (PANi) composite membranes by a filtration and Flash Welding method. MWNTs are acid treated to acquire better distribution in the composite membranes. PANi-nanofibers with a unique photothermal property are obtained by chemical oxidative polymerization of aniline. Dense MWNTs/PANi composite membranes are produced by filtration and a subsequent Flash Welding method. For the strong shear forces during the suction process, partly aligned MWNTs could be found in MWNTs/PANi composite membranes. Owing to the cross-linking structure of PANi nanofibers resulted by Flash Welding, composite membranes with an improved wettability could be obtained by intensity Flash irradiation. Furthermore, the wettability improved with the increasing of Flash times.

  • carbon nanotube templated polyaniline nanofibers synthesis Flash Welding and ultrafiltration membranes
    Nanoscale, 2013
    Co-Authors: Xia Wang, Deng-guang Yu, Yaozu Liao, Wei Chain, Xingui Li, Eric M V Hoek, Richard B Kaner
    Abstract:

    Electro-active switchable ultrafiltration membranes are of great interest due to the possibility of external control over permeability, selectivity, anti-fouling and cleaning. Here, we report on hybrid single-walled carbon nanotube (SWCNT)–polyaniline (PANi) nanofibers synthesized by in situ polymerization of aniline in the presence of oxidized SWCNTs. The composite nanofibers exhibit unique morphology of core–shell (SWCNT–PANi) structures with average total diameters of 60 nm with 10 to 30 nm thick PANi coatings. The composite nanofibers are easily dispersed in polar aprotic solvents and cast into asymmetric membranes via a nonsolvent induced phase separation. The hybrid SWCNT–PANi membranes are electrically conductive at neutral pH and exhibit ultrafiltration-like permeability and selectivity when filtering aqueous suspensions of 6 nm diameter bovine serum albumin and 48 nm diameter silica particles. A novel Flash Welding technique is utilized to tune the morphology, porosity, conductivity, permeability and nanoparticle rejection of the SWCNT–PANi composite ultrafiltration membranes. Upon Flash Welding, both conductivity and pure water permeability of the membranes improves by nearly a factor of 10, while maintaining silica nanoparticle rejection levels above 90%. Flash Welding of SWCNT–PANi composite membranes holds promise for formation of electrochemically tunable membranes.

  • Carbon nanotube/polyaniline nanofiber ultrafiltration membranes
    Journal of Materials Chemistry, 2013
    Co-Authors: Yaozu Liao, Xingui Li, Eric M V Hoek, Richard B Kaner
    Abstract:

    Development of electro-ultrafiltration membranes is an attractive target. We report electrically conducting ultrafiltration membranes by blending single-walled carbon nanotube/polyaniline (SWCNT/PANi) nanofibers into a polysulfone (PSf) matrix. By selecting the amount of nanofibers and applying a Flash Welding technique, the chemical structure, porosity, thermal stability, conductivity, hydrophilicity, permeability, and bovine serum albumin (BSA) rejection of these composite ultrafiltration membranes can be controlled. Addition of SWCNT/PANi nanofibers to the composites enhances the initial water permeability by 2.5–7.3 times and increases the hydrophilicity, and maintains considerable rejection of BSA from 39.8–73.7%. An electrical conductivity between 0.1 and 3.4 × 10−6 S cm−1 can be maintained over a broad pH range from 0.52–10.2. By regulating the Flash Welding intensity, the conductivity, permeability, and BSA rejection can be enhanced up to 600, 2, and ∼1.5 times, respectively.

  • Flash Welding of conducting polymer nanofibres
    Nature Materials, 2004
    Co-Authors: Jiaxing Huang, Richard B Kaner
    Abstract:

    The absorption of light by a material generates heat through non-radiative energy dissipation and exothermic photochemical reactions^ 1 . In nanostructured materials, the heat generated through photothermal processes will be confined within the individual nanostructures when heat transfer to neighbouring nanostructures and the environment is slow. This leads to unprecedented photothermal effects that cannot be observed in bulk materials, especially when a strong, pulsed light source is used^ 2 , 3 . Here we demonstrate an enhanced photothermal phenomenon with conducting polymer nanofibres in which a camera Flash causes instantaneous Welding. Under Flash irradiation, polyaniline nanofibres 'melt' to form a smooth and continuous film from an originally random network of nanofibres. This photothermal effect can be used to form asymmetric nanofibre films, to melt-blend polymer–polymer nanocomposites rapidly and to photo-pattern polymer nanofibre films.
