“…To investigate the versatility and formation mechanism of our polymerization method, an electropolymerizable monomer used for cathodic reduction, poly( p -phenylene vinylene), was also examined. Because p -xylylene-α,α′-bis(triphenylphosphonium chloride), the precursor of poly( p -phenylene vinylene) [ 34 ], is solid at room temperature, we dissolved it in toluene when we irradiated and scanned the electron beam. Even at the highest current density available to the ASEM instrument (i.e.…”

We propose a one-step nanopatterning method where liquid monomers are polymerized directly with an electron beam under an atmospheric pressure. The method allows precise positional control of an electron beam that induces electropolymerization based on an anodic oxidation only in the irradiated areas. Various versatile conjugated polymers, including polypyrrole, polyaniline and poly(3-hexylthiophene), have been directly polymerized from monomers without solvents and patterned by our one-step nanopatterning method. Vertically oriented arrays of nanorods several hundred nanometers in diameter with an aspect ratio (height to diameter) of around two were fabricated.

“…After deposition of PPV for 40 min, various bands related to PPV can be observed, similarly to what we have shown in our previous paper. 29 The bands around 1517 and 1430 cm −1 are due to C-C ring stretching. 30,31 A small band at 3024 cm −1 is related to the transvinylene C-H stretching mode.…”

International audienceThe electrochemical deposition of poly para-phenylene vinylene PPV into the pores of porous silicon PSi has been investigated using acetonitrile as solvent and p-xylylene- , -bis triphenylphosphonium chloride as precursor. PPV was successfully deposited onto various Si substrates and PSi layers. It was also deposited inside p+- and p-type PSi. The as-deposited PPV is strongly luminescent. The deposition was confirmed by optical photoluminescence, reflectivity and structural Fourier-transform infrared, scanning electron microscopy analysis. The deposited PPV was smooth without peeling on PSi layers. With strongly luminescent n+-type PSi, the rate of the deposition was limited by the large resistivity of PSi. The deposition was found dramatically affected by the PSi nanostructure through the diffusion of precursors in the pores and charge carrier transport in PSi

“…It can be noted that the electrochemical-assisted polymerization process is a convenient and versatile approach. Indeed, the polymer formation can be achieved by different mechanisms involving the formation of free-radical intermediates, the activation by light, the use of initiator, and the direct oxidation or reduction of monomer as it has been reported for poly(para-phenylene)vinylene (PPV) [ 18 ], polypyrrole (PPy) [ 19 ], poly(2-methacryloyloxy(ethyl) acetoacetate) [ 20 ], and poly(sulfonated phenol) [ 21 ], respectively.…”

Enhanced electrochemical performance of Lithium-ion batteries by conformal coating of polymer electrolyte

et al. 2014

This work reports the conformal coating of poly(poly(ethylene glycol) methyl ether methacrylate) (P(MePEGMA)) polymer electrolyte on highly organized titania nanotubes (TiO2nts) fabricated by electrochemical anodization of Ti foil. The conformal coating was achieved by electropolymerization using cyclic voltammetry technique. The characterization of the polymer electrolyte by proton nuclear magnetic resonance (1H NMR) and size-exclusion chromatography (SEC) shows the formation of short polymer chains, mainly trimers. X-ray photoelectron spectroscopy (XPS) results confirm the presence of the polymer and LiTFSI salt. The galvanostatic tests at 1C show that the performance of the half cell against metallic Li foil is improved by 33% when TiO2nts are conformally coated with the polymer electrolyte.
