Synthesis and characterization of trans-1,4-butadiene/isoprene copolymers: Determination of monomer reactivity ratios and temperature dependence
Chinese Journal of Polymer Science - Tập 32 - Trang 1068-1076 - 2014
A series of trans-1,4-butadiene/isoprene copolymers were prepared using the catalyst system TiCl4/MgCl2-Al(i-Bu)3 with bulk precipitation technology at different temperatures. Monomers reactivity ratios were calculated based on the Kelen-Tüdös (K-T) method and the Mao-Huglin (M-H) method. The influence of temperature on copolymer composition and polymerization rate was discussed in detail. The inc...... hiện toàn bộ
Synthesis and liquid crystalline behavior of side chain liquid crystalline polymers containing triphenylene discotic mesogens with different length flexible spacers
Chinese Journal of Polymer Science - Tập 33 - Trang 1245-1259 - 2015
A series of side chain liquid crystalline polymers (SCLCPs) containing triphenylene (Tp) units in the side chains, denoted as PMTS (without spacer) and PMTnS (n = 2, 3, 4, 6, which is the number of the methylene units between the main chain and Tp moieties in the side chains), with different lengths of spacers were synthesized through conventional free radical polymerization. The chemical structur...... hiện toàn bộ
Molecular Mobility in the Amorphous Phase Determines the Critical Strain of Fibrillation in the Tensile Stretching of Polyethylene
Chinese Journal of Polymer Science - Tập 38 - Trang 740-747 - 2019
The microstructural development of bimodal high density polyethylene subjected to tensile deformation was investigated as a function of strain after annealing at different temperatures by means of a scanning synchrotron small angle X-ray scattering (SAXS) technique. Two different deformation mechanisms were activated in sequence upon tensile deformation: intralamellar slipping of crystalline block...... hiện toàn bộ
Characterization of a modified silicon-containing arylacetylene resin with POSS functionality
Chinese Journal of Polymer Science - Tập 29 - Trang 726-731 - 2011
A modified silicon-containing arylacetylene resin with a well-defined organic-inorganic POSS functionality was successfully synthesized by Huisgen azide-alkyne 1,3-dipolar cycloaddition. The POSS hybridized resin exhibits excellent thermal properties which were characterized by differential scanning calorimetry (DSC) and thermogravimetric analyses (TGA). Scanning electron microscope (SEM) was used...... hiện toàn bộ
Diamines, CS2 and Monoisocyanide-participated Polymerizations for Large-scale Synthesis of Polythioureas and Thioformamide
Chinese Journal of Polymer Science - Tập 41 - Trang 1563-1576 - 2023
Multicomponent polymerizations (MCPs) are powerful tools to synthesize functional polymers with great structural diversity, low cost and high efficiency, which usually generate single polymer product. Herein, a robust one-pot diamines, CS2 and monoisocyanide-participated catalyst-free polymerization was developed at room temperature to produce polythiourea and thioformamide simultaneously in equal...... hiện toàn bộ
Polypropylene Separators with Robust Mussel-inspired Coatings for High Lithium-ion Battery Performances
Chinese Journal of Polymer Science - Tập 37 - Trang 1015-1022 - 2019
The performances of lithium-ion batteries (LIBs) are dependent on the wettability and stability of porous separators. Musselinspired coatings seem to be useful to improve the surface wettability of commercialized polyolefin separators. However, it is still a challenge to guarantee their stability under polar electrolytes. Herein, we report a facile and versatile way to enhance the wettability and ...... hiện toàn bộ

Synthesis of self-assemble pH-responsive cyclodextrin block copolymer for sustained anticancer drug delivery
Chinese Journal of Polymer Science - Tập 35 - Trang 924-938 - 2017
Well-defined pH-responsive poly(ε-caprolactone)-graft-β-cyclodextrin-graft-poly(2-(dimethylamino)ethylmethacrylate)-co-poly(ethylene glycol) methacrylate amphiphilic copolymers (PCL-g-β-CD-g-P(DMAEMA-co-PEGMA)) were synthesized using a combination of atom transfer radical polymerization (ATRP), ring opening polymerization (ROP) and “click” chemistry. Successful synthesis of polymers was confirmed ...... hiện toàn bộ
Chlorinated Effects of Double-Cable Conjugated Polymers on the Photovoltaic Performance in Single-Component Organic Solar Cells
Chinese Journal of Polymer Science - Tập 41 - Trang 187-193 - 2022
The recently emerged double-cable conjugated polymers have come into focus due to their significantly improved power conversion efficiencies (PCEs) in single-component organic solar cells (SCOSCs). In this work, the effect of chlorination in double-cable conjugated polymers with linear benzodithiophene backbone and pendant perylene bisimide on the photovoltaic performance in SCOSCs has been studie...... hiện toàn bộ
pH-sensitive wettability induced by topological and chemical transition on the self assembled surface of block copolymer
Chinese Journal of Polymer Science - Tập 32 - Trang 92-97 - 2013
pH-sensitive wettability of polystyrene-b-poly(4-vinylpyridine) (PS-b-P4VP) self assembled films, exhibiting superoleophobicity under water and hydrophilicity at low pH value, and oleophobicity under water and hydrophobicity at neutral condition, has been realized. The wettability properties resulted from the surface topological and chemical transition, which were confirmed by in situ AFM measurem...... hiện toàn bộ
