“…Chemical polymerization is a conventional method to produce high quality PANI in a large scale. The reaction is initiated by an oxidizing agent such as ammonium persulfate (APS) [ 132 , 133 ], H 2 O 2 [ 134 ], benzoyl peroxide [ 135 , 136 ], ferric chloride [ 137 , 138 ] and chloroaurate acid [ 139 , 140 ]. APS is considered to be an optical choice due to its high yield.…”

As a promising desalination technology, capacitive deionization (CDI) have shown practicality and cost-effectiveness in brackish water treatment. Developing more efficient electrode materials is the key to improving salt removal performance. This work reviewed current progress on electrode fabrication in application of CDI. Fundamental principal (e.g. EDL theory and adsorption isotherms) and process factors (e.g. pore distribution, potential, salt type and concentration) of CDI performance were presented first. It was then followed by in-depth discussion and comparison on properties and fabrication technique of different electrodes, including carbon aerogel, activated carbon, carbon nanotubes, graphene and ordered mesoporous carbon. Finally, polyaniline as conductive polymer and its potential application as CDI electrode-enhancing materials were also discussed.

“…It can be processed in both the insulating emeraldine base (EB) form [14] and in the conducting emeraldine salt (ES) form [15] (σ<10 -10 S/cm and σ>1 S/cm, respectively [16]). Recently, bulk production of PAni has been reported via interfacial polymerization, a chemical oxidative polymerization of aniline at organic-aqueous acid interphase [17][18][19].…”

Different types of crystalline carbon nanomaterials were used to reinforce polyaniline (PAni) for use in electromechanical bilayer bending actuators. The objective is to analyze how the structural properties of the nanocarbons affect the in-situ produced PAni structure and subsequent final composite actuator behavior. Nanocarbons investigated were multiwalled carbon nanotubes, nitrogen-doped carbon nanotubes, helical-ribbon carbon nanofibers and graphene oxide, each one presenting different shape and structural characteristics. Films of nanocarbon-PAni composite were tested in a liquid electrolyte cell system. Experimental design was used to select type of nanocarbon filler and composite loadings that showed a good balance of electromechanical properties. Raman spectroscopy suggests good interaction between PAni and the nanocarbon fillers.Electron microscopy showed best nanofiller dispersion for graphene oxide, followed by multiwall carbon nanotubes. On the contrary, nitrogen doped nanotube composites showed dispersion problems, and thus a poor performance. Multiwall carbon nanotubes composite actuators had the best performance based on the combination of bending angle, bending velocity and maximum working cycles (measured considering nanofiller loading and applied voltage), while graphene oxide attained similar good performance.

“…[22][23][24] Interfacial polymerization is an effective method for suppressing the overgrowth or secondary growth of polymers and has been successfully applied to make polyaniline nanobers and nanoparticles. 15,[25][26][27] Second, in the case of homogeneous polymerization, there are restriction on the selection of the oxidizing agents, due to non-solubility of oxidizing agents and monomers in the same solvent. This problem is more aggravated in the polymerization of PAHs, as they are generally insoluble in all aqueous media.…”

“…Using interfacial polymerization, however, avoids the need to use just a single solvent that must dissolve both the oxidizing agent and monomer; instead, it allows one to use e.g., a biphasic medium consisting of organic solvent and aqueous acid or water alone to dissolve the monomer and oxidant, respectively. Third, interfacial polymerization also enables us to synthesize various different morphologies, such as nanorods, nanotubes, nanosheets, nanospheres, and nano-bers; 26,[28][29][30] for example, one-dimensional nanotubes and three-dimensional nanospheres of polyaniline and polypyrrole. [31][32][33][34] Furthermore, the post-treatments of interfacial polymerization, such as removal of the residual oxidant from the products, are easy to operate, because the major part of the residual oxidant is present in a single phase.…”
