A novel polytriphenylamine derivative, poly(4-carbamoyl-N,N-diphenylaniline-2,2,5,5-tetramethyl-pyrrolin-1-oxyl) (PTPA-PO) has been synthesized and utilized for the fabrication of the cathode material for organic rechargeable batteries for the first time. The molecular structure, morphology, and electrochemical performance of the obtained polymers were characterized by Fourier transform infrared spectroscopy...
We develop a coarse-grained Monte Carlo model for the anchoring of cationic polymers onto a phosphatidyl-choline (PC) lipid monolayer, doped with univalent phosphatidylserine (PS) and tetravalent phosphatidylinositol 4, 5-bisphosphate (PIP2) anionic lipids. Using this model, we extensively explore the effects of important factors on the structural alterations of the polymers/monolayer complex, including...
Structured thermoset–thermoplastic hybrid nanoparticles and composite coatings were successfully synthesized through a novel one-pot approach. Both the polyaddition of epoxy curing and the free radical polymerization of various vinyl monomers were performed in sequence in miniemulsion droplets. Benefiting from the precise control of the compatibility between thermoset phase (epoxy monomer/amine curing...
A bisphenol monomer (4-methoxy) phenylhydroquinone (Me-HQ) was prepared and further polymerized with 2,2,3,3,4,4,5,5,6,6,7,7-dodeca-fluoro-1,8-octanediol (12F-diol) and decafluorobiphenyl (DFBP) to obtain highly fluorinated aromatic-aliphatic copolyethers containing methoxy groups. After demethylation and the reaction with epoxy chloropropane, a series of novel highly fluorinated aromatic-aliphatic...
A series of novel side-chain-type sulfonated hydroxynaphthalene poly(aryl ether ketone)s (SHNPAEKs) containing hydroxyl groups was synthesized by post grafted method and the sulfonated degree (Ds) of the polymers could be well controlled. The resulting polymers were characterized by 1 H NMR, FT-IR and thermogravimetric analysis (TGA). Meanwhile, the membrane properties for fuel cell applications...
The re-assembly behaviors of spherical micelles of the polystyrene-b-poly(acrylic acid) (PS-b-PAA) diblock copolymer in different solvent mixtures were investigated using dynamic light scattering, transmission electron microscopy and atomic force microscopy. Depending on the nature of the solvent, PS-b-PAA micelles re-assembled from spheres to nanorings in toluene or to necklace-like aggregates in...
Novel side-chain-type sulfonated poly(arylene ether ketone) with pendant sulfoalkyl groups (SPAEK-xx) were synthesized by post-sulfonation method. Their structures were confirmed by FT-IR and NMR spectra. The all obtained membranes had excellent thermal stability and mechanical properties. The side-chain-type SPAEK films showed good dimensional stability, and their water uptake and swelling ratio...
