“…The conductivity for SITP‐60 (0.14 S/cm), SITA‐60 (0.27 S/cm), and CIT‐60 (0.013 S/cm) is one or two orders of magnitude lower than that for PANI (4.02 S/cm, Table S2). Since the conductivity of PANI resembles that of PANIs reported in the literature, the decreased conductivity for the isotruxene–PANI hybrid systems reflects the effect of the isotruxene π‐scaffold on the polaron transportation in the solid state.…”

“…A popular approach to mitigate these problems is to create composites with other conducting materials such as activated carbons, carbon nanotubes, graphenes, and metal oxide nanoparticles . Another alternative approach of intrinsic structural modification by introducing either substituents or branching units is also effective but largely unexplored, particularly for hybrid systems that contain different π‐conjugated scaffolds …”

The synthesis, structural characterization, and electrochemical properties of a series of isotruxenepolyaniline (PANI) hybrid systems (SITPs, SITAs, and CITs) are reported. The syntheses were performed by in situ chemical oxidative polymerization of aniline in the presence of isotruxene additives ITP and/or ITA at specific aniline-to-additive molar ratios. The polymers SITPs and SITAs display granular morphology, but for the polymers CITs a spherical morphology with a diameter of 300-500 nm is found. These hybrid systems display electrochemical capacitive performance superior to those of the parent PANI prepared under the same condition (e.g., 385-463 vs. 181 F/g at 3 mA/cm 2 current density during charge-discharge test). Molecular (star-shaped or hyperbranched vs. linear topology) and supramolecular (isotruxene-PANI π-π and cation-π interactions) models in accounting for the observed morphology and electrochemical properties are provided. . His current researches include (1) Light-and voltage-gated molecular machines; (2) Stimuli-responsive photoluminescent organic and organometallic systems; (3) Electronic properties of π-conjugated oligomers and polymers.

We report a novel approach for the preparation of multilayer polymers for protein and bacterial antifouling. Stainless steel (SS) was used as the model substrate. SS was first coated with a hybrid polymer film, which was formed by simultaneous hydrolytic polycondensation of 3‐aminopropyltriethoxysilane and polymerization of dopamine (HPAPD). Then p‐phenylenediamine was chemically bound to SS–HPAPD. The amino groups of p‐phenylenediamine were used as anchors for the growth of polyaniline nanofiber arrays by polymerization of aniline in situ. The nanofibers were further silicificated using 3‐aminopropyltriethoxysilane, 3‐mercaptopropyltriethoxysilane, vinyltrimethoxysilane and octyltrimethoxysilane, conferring various functional groups. The silicificated polyaniline nanofiber arrays (SPNAs) become hydrophobic. Separate tests for the adsorption of proteins of small (54 kDa) and large (2 × 90 kDa) molecular weights and Escherichia coli on the SPNAs were performed. The results show that the SPNAs can resist the adhesion of the proteins with an average efficiency of 96.3 ± 3.2%, and the SPNAs can resist the adhesion and colonization of Escherichia coli with an average efficiency of 97.5 ± 3.8%. The methodology of forming SPNAs on SS is of general utility and has wide application potential. © 2017 Society of Chemical Industry

Self‐Supported Electrocatalysts Derived from Nickel‐Cobalt Modified Polyaniline Polymer for H₂‐Evolution and O₂‐Evolution Reactions

The water splitting aims to produce H 2 for fuel cells and a number of industrial processes such as the ammonia synthesis and the metals refining. There is actually a major limitation about the development of cost-effective and efficient electrocatalysts to lower the cell voltage that must be overcome to perform sequentially the overall reaction that is 2H 2 O !2H 2 + O 2. In the present study, we combined Ni and Co as the promising alternative catalytic metals to Pt-group metals as well as N and S as the doping elements to fabricate self-supported electrocatalysts for hydrogen evolution (HER) and oxygen evolution (OER) in alkaline media. To these ends, the polymerization of the aniline into polyaniline (PANI) in the presence of Ni(II) and Co(II) followed by calcination in air resulted in the formation of heterogeneous catalytic materials self-supported onto a matrix made of C, N, S, Ni and Co. Enhanced activity and durability were recorded for the hybrid and bimetallic PANI-NiCo composite.
