【Polymer Chemistry】A pH and redox dual responsive homopolypeptide: synthesis, characterization, and application in "smart" single-walled carbon nanotube dispersion
Abstract:
A homopolypeptide, namely poly(S-(2-carboxylethyl)-L-cysteine) (PCELC), with pH and redox dual responsiveness was prepared by ring-opening polymerization of S-(2-(methoxycarbonyl)ethyl)-L-cysteine based N-carboxyanhydride (MCELC-NCA) and subsequent hydrolysis. The pH-induced solution phase transition of PCELC was at pH = ～4.50 as revealed by DLS and UV-vis spectroscopy. The th...

【41 Polymer】 Synthesis and linear rheological property of comb-like styrene-based polymers with a high degree of long-chain branching
A series of model comb-like polymers (PSVS-g-PS) with high branching degree were synthesized by nucleophilic substitution reaction between iodinated copolymer of styrene (St) with 4-(vinylphenyl)-1-butene (VSt) (PSVSI, backbone) and living polystyrene lithium (PSLi, side chain). This method is a facile way for modular synthesis of graft copolymers based on living anionic polymerization and hydrozi...

【33 Polymer Degradation and Stability】 Synergistic effect of fumed silica with Ni2O3 on improving flame retardancy of poly(lactic acid)
A novel combined catalyst of fumed silica (SiO2) with Ni2O3 was demonstrated to be more efficient than SiO2 or Ni2O3 alone in enhancing the char yield of poly(lactic acid) (PLA) and improving its char layer structure, which greatly enhanced the flame retardancy of PLA. The results of field-emission scanning electron microscope, transmission electron microscope, X-ray diffraction, Fourier-transform...

【34 Polymer Degradation and Stability】 Synergistic effect of activated carbon and Ni2O3 in promoting the thermal stability and flame retardancy of polypropylene
A novel combined catalyst of activated carbon (AC) with Ni2O3 was demonstrated to be much more efficient than AC or Ni2O3 alone in enhancing the char yield of polypropylene (PP) and improving its char layer structure, which greatly improved the thermal stability and flame retardancy of PP. The results of X-ray diffraction, field-emission scanning electron microscope and transmission electron micro...

【35 Polymer】 Combination of fumed silica with carbon black for simultaneously improving the thermal stability, flame retardancy and mechanical properties of polyethylene
The combination of fumed silica (SiO2) with carbon black (CB) for improving thermal stability, flame retardancy and mechanical properties of linear low density polyethylene (LLDPE) was investigated. The temperature at the maximum weight loss rate of LLDPE was dramatically increased by 92 °C, and the peak value of heat release rate measured by cone calorimeter was significantly reduced by 80.7%. T...

An effectively inhibiting lithium dendrite growth in-situ-polymerized gel polymer electrolyte
Polyacrylate polymer is a promising polymer matrix for gel polymer electrolyte (GPE ) in lithiu m-ion batteries. He rein, in-situ polymerized poly(ethylene glycol phenyl etheracrylate) (PEGPEA) based GPE combined with 1 M LiPF6 in ethylene carbonate/dimethyl carbonate/ethyl methyl carbonate (EC/DMC/EMC, 1:1:1 in volume) solvents was introduced. The maximum recoverable strain of the in-situ polym...

2018-Materials：Preparation and Characterization of PVA Alkaline Solid Polymer Electrolyte with Addition of Bamboo Charcoal
Natural bamboo charcoal (BC) powder has been developed as a novel filler in order to further improve performances of the polyvinyl alcohol (PVA)-based alkaline solid polymer electrolyte (ASPE) by solution casting method. X-ray diffraction patterns of composite polymer electrolyte with BC revealed the decrease in the degree of crystallinity with increasing content of BC. Scanning electron microscop...

Covalent immobilization of TiO2 within macroporous polymer monolith as a facilely recyclable photocatalyst for water decontamination
This study focused on the covalent immobilization of TiO2 on the surface of a porous polymer monolith by a two-step method. Firstly, porous polymeric monolith with trimethoxysilane anchor groups was fabricated by w/o emulsion templated copolymerization of vinyl acetate (VAc) and methacryloxypropyl-trimethoxysilane (MPS). Then, anatase TiO2 were covalently immobilized within the voids of poly(VAc-M...
