We successfully prepared two different classes of hypercrosslinked porous organic polymers (HPPs)—the tetraphenylethene (TPE) and (4-(5,6-Diphenyl-1H-Benzimidazol-2-yl)-triphenylamine (DPT) HPPs—through the Friedel−Crafts polymerization of tetraphenylethene and 4-(5,6-diphenyl-1H-benzimidazol-2-yl)-triphenylamine, respectively, with 1,4-bis(chloromethyl)benzene (Ph-2Cl) in the presence of anhydrous FeCl3 as a catalyst. Our porous materials exhibited high BET surface areas (up to 1000 m2 g−1) and good thermal stabilities. According to electrochemical and dyes adsorption applications, the as-prepared DPT-HPP exhibited a high specific capacitance of 110 F g−1 at a current density of 0.5 A g−1, with an excellent cycling stability of over 2000 times at 10 A g−1. In addition, DPT-HPP showed a high adsorption capacity up to 256.40 mg g−1 for the removal of RhB dye from water.

Polypyrrole with hierarchical dendritic structures assembled with cauliflower-like structure of nanospheres, was synthesized by chemical oxidation polymerization. The structure of polyryrrole was characterized by Fourier transform infrared spectrometer and scanning electron microscopy. The electrochemical performance was performed on CHI660 electrochemical workstation. The results show that oxalic acid has a significant effect on morphology of PPy products. The hierarchical dendritic PPyOA(3) electrodes possess a large specific capacitance as high as 744 F/g at a current density of 0.2 A/g and could achieve a higher specific capacitance of 362 F/g even at a current density of 5.0 A/g. Moreover, the dendritic PPy products produce a large surface area on the electrode through the formation of the channel structure with their assembled cauliflower-like morphology, which facilitates the charge/electron transfer relative to the spherical PPy electrode. The spherical dendritic PPyOA(3) electrode has 58% retention of initial specific capacitance after 260 cycles. The as-prepared dendritic polypyrrole with high performance is a promsing electrode material for supercapacitor.

A homogeneous Ni (OH)2/ carbon nanotubes (CNTs) nanocomposite with excellent supercapacitive performance has been synthesized via a facile chemical precipitation. The microstructure and morphology of Ni (OH)2/CNTs nanocomposite were investigated by XRD, SEM and TEM. It presented an ideal morphology with the nanosized Ni (OH)2 particles homogeneously growing on the CNTs. The electrochemical performance of the Ni (OH)2/CNTs nanocomposite was test by cyclic voltammetry, galvanostatic charge−discharge and electrochemical impedance spectroscopy techniques. The synthesized Ni (OH)2/CNTs nanocomposite shows superior electrochemical performance, including high capacitance, excellent rate capability and good cycle life. The homogeneous Ni (OH)2/ CNTs nanocomposite exhibited a high specific capacitance of 1741 F g-1 at a current density of 1A g-1 and maintained a good stability after 5000 cycles at 10A g-1`, suggesting that it can be a promising candidate for supercapacitor.
