Abstract The preparation and polymerization of a bifunctional imidazolium‐based ionic liquid (IL) monomer that incorporates both vinyl group thiophene moiety is reported. Potentiodynamic electropolymerization the produces an optically birefringent polymer film strongly adheres to electrode surface. Fourier transform IR spectroscopy shows occurs through thienyl groups. Cylic voltammetry (CV) used determine oxidation potential (1.66 V) electrochemical bandgap, E g , 2.45 eV. exhibits...

Preparation of a liquid-crystalline ionic-liquid (IL)-based interpenetrating polymer network (IPN) is described. The IPN prepared sequentially by first photopolymerizing self-assembled aqueous mixture an IL monomer (1-(10-(acryloyloxy)decyl)-3-methylimidazolium chloride) that possesses acryloyl moiety at the terminus C10 alkyl chain cation. In second step, acrylate counteranion introduced and then photopolymerized to yield durable self-supporting polymer. Thermal analysis indicates formation...

Thermal free radical polymerization of a self-assembled, bifunctional imidazolium-based ionic liquid (IL) monomer bearing both vinyl and thienyl groups is reported. FT-IR spectroscopy proves that the occurs through groups. The polymer resistant to swelling in water common organic solvents. as-synthesized can be readily chemically doped de-doped. Small-angle X-ray scattering studies indicate dried adopts weakly ordered lamellar structure. p-doped, ethanol-solvated undergoes structural...

M. A. Firestone et al. present a polymer that incorporates an electronic component with ionic liquid and produces mixed conductor on page 2063. Electropolymerization of bifunctional imidazolium-based monomer incorporating both vinyl thiophene groups yields liquid-crystalline adopts interconnected network structure formed by two orthogonally oriented lamellar sheets. The structural ordering leads to enhanced electrical conductivity.
