Density functional theory (DFT) calculations on a model system agree with CoED bond strengths decreasing same order. effect ]‐mediated radical polymerization VOAc...
Abstract The high failure strain of thermoplastic elastomers (TPEs) is a very desirable feature for rechargeable Li-ion batteries by improving the lifetime specific capacity anode materials that undergo mechanical fractures induced large volume variations. In this work, poly(styrene- b -2-hydroxyethyl acrylate) called PS- -PHEA was synthesized nitroxide meditated polymerization method. Owing to use polystyrene macroinitiator (SG1), suitable TPE copolymer with long hydroxyethyl acrylate...
The recent advances in wearable technologies had caused a surge the demand for stretchable Li-ion microbatteries. Herein, special design based on micropillar electrodes supported metallic serpentines has been investigated to achieve fabrication of functionning device. Besides achieving high areal capacity values like 2.5 mA h cm−2 at C/10 (i.e. 0.07 cm−2), micropillars make system reversibly stretchable. Electrochemical tests revealed excellent performance when micropower source was...

The molybdenum(III) coordination complexes MoX(3)(PMe(3))(3) (X = Cl, Br, and I) are capable of controlling styrene polymerization under typical atom transfer radical (ATRP) conditions, in conjunction with 2-bromoethylbenzene (BEB) as an initiator. process is accelerated by the presence Al(OPr(i))(3) a cocatalyst. Electrochemical synthetic studies aimed at identifying nature spin trap have been carried out. cyclic voltammogram shows partial reversibility (increasing order Cl < Br for...
Novel semiconductor block copolymers were synthesized using nitroxide-mediated radical polymerization (NMRP). They are comprised of a hole conductor carrying tetraphenylbenzidine pendant units (PVDMTPD) and second poly(4-vinylpyridine) (P4VP) suitable for the preferential incorporation n-type nanocrystals. The conditions NMRP both monomers optimized in order to get macroinitiators with well-defined molecular weights very low polydispersity (<1.2). resulting polymers exhibit lamellar...
Separation of parent homopolymers, polystyrene and poly(ethylene oxide), from the triblock copolymer polystyrene-b-poly(ethylene oxide)-b-polystyrene was investigated by means liquid chromatography techniques. Overall suitability evaluated compared for size exclusion chromatography, (SEC), under critical conditions enthalpic interactions (LC CC), limiting desorption LCD). Among these techniques, LC LCD only one able to fully separate block copolymers both their homopolymers in single run....
Compound Al(OiPr)3 is shown to catalyze the halide-exchange process leading from [Mo(Cp)Cl2(iPrN=CH-CH=NiPr)] and CH3CH(X)COOEt (X=Br, I) mixed-halide complexes [Mo(Cp)ClX(iPrN=CH-CH=NiPr)].
