“…The production of novel polymeric nanocomposites have been widely studied by the current applications on nanosized inorganic fillers in the food packaging field, barrier applications, sensors, antimicrobial, conductive, coatings, antiballistic products and other materials [1][2][3][4] . The new generation of these polymer nanocomposites contains nitrides (TiN, CrN, ZrN, BN), carbides (WC, SiC, B 4 C), borides (WB, ZrB 2 , TiB 2 , CrB 2 ), metal oxides (Al 2 O 3 , Fe 3 O 2 , MgO, CeO 2 , TiO 2 , Y 2 O 3 , SiO 2 , ZrO 2 ), carbon nanotubes, cellulose nanofibrils, and other kind of nanoparticles as disperse phase [5][6][7] .…”

In this study, polymeric nanocomposites based on poly(methyl methacrylate) (PMMA) and silicon carbide (SiC) nanoparticles were prepared by radical mass polymerization in the presence of filler. Nanoparticles of SiC with and without surface treatment with organosilane were obtained .The nanocomposites were characterized by X-ray fluorescence (XRF), infrared spectroscopy (FTIR), thermogravimetry (TGA) and Field Emission Gun Scanning Electron Microscopy (FEG SEM) with an energy dispersive x-ray spectroscopy (EDS) detector. The produced nanocomposites showed welldispersed SiC incorporation in the PMMA matrix. The results pointed that the surface treatment on SiC fillers was successful on enhancing the interaction between the organic matrix and the inorganic filler.

The preparation of highly conductive, high-surface-area, heteroatom-doped, porous carbon nanocomposite materials with enhanced electrochemical performance for sustainable energy-storage technologies, such as supercapacitors, is challenging. Herein, a route for the large-scale synthesis of nitrogen-doped porous carbon wrapped partially exfoliated carbon nanotubes (N-PPECNTs) with an interconnected hierarchical porous structure, as an advanced electrode material that can realize several potential applications for energy storage, is presented. Polypyrrole conductive polymer acts as both nitrogen and carbon sources that contribute to the pseudocapacitance. Partially exfoliated carbon nanotubes (PECNTs) provide a high specific surface area for ion and charge transportation and act as a conductive matrix. The derived porous N-PPECNT displays a nitrogen content of 6.95 at %, with a specific surface area of 2050 m g , and pore volume of 1.13 cm g . N-PPECNTs, as an electrode material for supercapacitors, exhibit an excellent specific capacitance of 781 F g at 2 A g , with a high cycling stability of 95.3 % over 10 000 cycles. Furthermore, the symmetric supercapacitor exhibits remarkable energy densities as high as 172.8, 62.7, and 53.55 Wh kg in 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide ([BMIM][TFSI]), organic, and aqueous electrolytes, respectively. Also, biocompatible hydrogel and polymer gel electrolyte based, stable, flexible supercapacitors with excellent electrochemical performance could be demonstrated.

Polymeric carbon / activated carbon aerogels were synthesized through sol-gel polycondensation reaction followed by the carbonization at 800 ºC under Argon (Ar) atmosphere and subsequent physical activation under CO2 environment at different temperatures with different degrees of burn-off. Significant increase in BET specific surface area (SSA) from 537 to 1775 m 2 g-1 and pore volume from 0.24 to 0.94 cm 3 g-1 was observed after physical activation while the pore size remained constant (around 2nm). Morphological characterization of the carbon and activated carbons was conducted using X-ray diffraction (XRD) and Raman spectroscopy. Fourier-transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) were used to investigate the effect of thermal treatment (surface cleaning) on the chemical composition of carbon samples. Cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) were used to analyse the capacitive and resistive behaviour of non-activated/ activated/ and surface cleaned activated carbons employed as electroactive material in a two electrode symmetrical electrochemical capacitor (EC) cell with 6M KOH solution used as the electrolyte. CV measurements showed improved specific capacitance (SC) of 197 Fg-1 for activated carbon as compared to the SC of 136 Fg-1 when non-activated carbon was used as electroactive material at a scan rate of 5mVs-1. Reduction in SC from 197 Fg-1 to 163 Fg-1 was witnessed after surface cleaning at elevated temperatures due to the reduction of surface oxygen function groups. 2 The result of EIS measurements showed low internal resistance for all carbon samples indicating that the polymeric carbons possess a highly conductive three dimensional crosslinked structure. Because of their preferred properties such as controlled porosity, exceptionally high specific surface area, high conductivity and desirable capacitive behaviour, these materials have shown potential to be adopted as electrode materials in electrochemical capacitors.
