Effect of the polymer-substrate interactions on crystal nucleation of polymers grafted on a flat solid substrate as studied by molecular simulations
https://www.sciencedirect.com/science/article/pii/S0032386117306791
The crystallization behaviors of three types of polymer systems grafted on a flat solid substrate with different grafting densities were investigated by dynamic Monte Carlo simulations. For both of the systems with low and medium grafting densities, nucleation induction period becomes shorter with the increasing polymer-subst...

An encouraging recyclable synergistic hydrogen bond crosslinked highperformance polymer with visual detection of tensile strength
We have successfully constructed a novel type of recyclable crosslinked protonated polybenzotriazole ether sulfone (PBTSH+), which possessed outstanding thermal stability and mechanical properties. More importantly, the tensile strength of the resulting crosslinked films could be visually detected by taking advantage of the transparency decreasing effect of synergistic hydrogen bonds between pro...

Enhanced carbon dioxide capture in an indolebased microporous organic polymer via synergistic effects of indoles and their adjacent carbonyl groups
A carbonyl-functionalized indole-based microporous organic polymer (PKIN) was designed and synthesized in the presence of the FeCl3 catalyst by a facile direct oxidative coupling reaction. Taking advantage of the synergistic effect of indoles and their adjacent carbonyl moieties on carbon dioxide (CO2), the CO2 uptake capacity of the polymer reaches up to 6.12 mmol g-1 (1.0 bar, 273 K)...

【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%.
