【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...

【Chinese Journal of Polymer Science】A biomimetic surface for infection-resistance through assembly of metal-phenolic networks
Abstract:
Despite the fact that numerous infection-resistant surfaces have been developed to prevent bacterial colonization and biofilm formation, developing a stable, highly antibacterial and easily produced surface remains a technical challenge. As a crucial structural component of biofilm, extracellular DNA (eDNA) can facilitate initial bacterial adhesion, subsequent development, and...

【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...

【48 Chinese Journal of Polymer】 Polyvinyl alcohol/GO-MMT nanocomposites: Preparation, structure and properties
A facile, efficient and environment friendly method is established to prepare poly(vinyl alcohol) (PVA) based graphene oxide-montmorillonite (GO-MMT) nanocomposites in aqueous media. GO-MMT nanohybrid is obtained by the combination of GO and MMT in water without any reducing or stabilizing agents. The formation of GO-MMT nanohybrid is due to the hydrogen bonding and crosslinking effects. The sodiu...

【49 Chinese Journal of Polymer Science】 The effect of particle shape on the structure and rheological properties of carbon-based particle suspensions
The structure and rheological properties of carbon-based particle suspensions, i.e., carbon black (CB), multi-wall carbon nanotube (MWNT), graphene and hollow carbon sphere (HCS) suspended in polydimethylsiloxane (PDMS), are investigated. In order to study the effect of particle shape on the structure and rheological properties of suspensions, the content of surface oxygen-containing functional gr...

【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...

【13 Journal of Applied Polymer Science】 In situ chemically crosslinked chitosan membrane by adipic acid
Adipic acid, which is nontoxic, was used to dissolve chitosan. The chitosan/adipic acid solution was used to prepare chitosan membrane. After being heated at 80-100 °C, the membrane was in situ chemically crosslinked by adipic acid, as verified by Fourier transform infrared and wide‐angle X‐ray diffractometer analysis. The crosslinked membrane did not collapse even without treatment in alkaline...

【European Polymer Journal】Preparation and mechanical properties of strong and tough poly (vinyl alcohol)-polypeptide double-network hydrogels
Abstract：
Poly(vinyl alcohol) (PVA)-polypeptide double-network hydrogels with various ionic liquid (IL)-based polypeptides were prepared by a freezing/thawing method. Tensile tests revealed that the stiffness and toughness of the PVA hydrogels were significantly improved (e.g., 6.3 times the Young’s modulus and 5.8 times the work of extension) by incorporation of IL-based polypeptides. An...
