In this study, strong multiwalled carbon nanotube (MWNT)–polyimide (PI) matrix interfaces were designed and constructed to obtain high-performance nanocomposites via in-situ polymerization. MWNTs with reactive amino groups were produced by the covalent linking of phenylenediamine to the surface of MWNTs by amide bonds; this material exhibited excellent dispersibility and compatibility with the PI matrix. The incorporation of amine-functionalized MWNT (MWNT-NH2) significantly improved the macroscopic properties of the PI-based nanocomposites. A 50.5% increase in the tensile strength and an 83.1% increase in the Young’s modulus were achieved by 3.0 wt% MWNT-NH2 loading. Furthermore, the storage modulus, thermal stability, and glass transition temperature of the nanocomposite clearly increased by adding MWNT-NH2. The success of this method provides a good rational for developing high-performance polymer-based nanocomposites.

Supercapacitor Application

Novel unique fabrication of ZnO nanoparticles decorated graphene beaded carbon nanofibers (G-CNF) encapsulated by polyaniline (PANI) nanocomposites through three steps by electrospinning, hydrothermal and in-situ polymerization is reported. As-synthesized G-CNF/ZnO/PANI and CNF/ZnO/PANI nanocomposites were comparatively studied by scanning electron microscopy and electrochemical characterizations for supercapacitor application. Electrochemical measurements of G-CNF/ZnO/PANI electrode revealed the maximum specific capacitance, discharge time, energy density and power density as compared to that of CNF/ZnO/PANI indicating the increase in surface area due to graphene incorporation in electrospinning of carbon nanofibers. The combination of electric double layer charge (EDLC) capacitance from high surface area of G-CNF and pseudo-capacitance from PANI and ZnO nanoparticles facilitates the synergistic effect of ternary components to enhance the electrochemical performance of G-CNF/ZnO/PANI nanocomposite.
