Response of bi-disperse polyelectrolyte brushes to external electric fields — A numerical self-consistent field theory studyChinese Journal of Polymer Science - Tập 35 - Trang 98-107 - 2016
Cong Kang, Shuang-liang Zhao, Chao-hui Tong
The self-consistent field theory has been employed to numerically study the response of bi-disperse flexible polyelectrolyte (PE) brushes grafted on an electrode to electric fields generated by opposite surface charges on the PE-grafted electrode and a second parallel electrode. The numerical study reveals that, under a positive external electric field, the shorter and negatively charged PE chains...... hiện toàn bộ
Structural Evolution of PGA Nascent Fiber during Single Low-Temperature and Segmented High-Temperature Hot StretchingChinese Journal of Polymer Science - Tập 41 Số 7 - Trang 1078-1092 - 2023
Miao, Yu-Shuang, Cui, Hua-Shuai, Guo, Jin, Zhu, Jin-Tang, Li, Yi-Guo, Wang, Zong-Bao
Polyglycolide (PGA) fibers applied as surgical sutures strongly depend on their microstructure. The structural evolution of PGA nascent fibers during single low-temperature stretching and segmented high-temperature stretching was analyzed based on a combination of in situ WAXD/SAXS and DSC measurements. The results indicated that the hot stretching was conducive to the crystal perfection and the l...... hiện toàn bộ
Force-Extension Curve of an Entangled Polymer Chain: A Superspace ApproachChinese Journal of Polymer Science - Tập 39 - Trang 1345-1350 - 2021
Huan Gong, Jian-Feng Li, Hong-Dong Zhang, An-Chang Shi
The statistical mechanics of an ideal polymer chain entangled with static topological constraints is studied using a superspace approach, in which the probability distribution of the polymer is obtained as solutions of the Fokker-Planck equation in a superspace with an inner structure characterized by the n-generator free group. The theory predicts that the force-extension curve of the polymer und...... hiện toàn bộ
Micellization and gelation of the double thermoresponsive ABC-type triblock copolymer synthesized by RAFTChinese Journal of Polymer Science - Tập 34 - Trang 965-980 - 2016
Na-er Guang, Shou-xin Liu, Xuan Li, Lei Tian, Hong-guang Mao
A double thermoresponsive ABC-type triblock copolymer (poly(ethyleneglycol)-block-poly(2-(2-methoxyethoxy) ethyl methacrylate)-block-poly(2-(2-methoxy ethoxy) ethyl methacrylate-co-oligo(ethylene glycol) methyl ether methacrylate, PEG-b-PMEO2MA-b-P(MEO2MA-co-OEGMA)) was designed and synthesized by reversible additionfragmentation chain transfer polymerization (RAFT). The ABC-type triblock copolyme...... hiện toàn bộ
The Anion Binding Affinity Determines the Strength of Anion Specificities of Thermosensitive PolymersChinese Journal of Polymer Science - Tập 39 - Trang 1351-1356 - 2021
Lei-Lei Lian, Si-Yuan Xu, Hai-Yang Yuan, Guang-Ming Liu
In this work, we demonstrate that the strength of anion specificities of thermosensitive polymers is determined by the affinity of direct anion binding to the polymers. We have prepared a series of thermosensitive statistical copolymers with distinct thermoresponsive behaviors. The anions can specifically interact with the different types of thermosensitive polymers in very different strengths. A ...... hiện toàn bộ
Thienylmethylene Oxindole Based Conjugated Polymers via Direct Arylation Polymerization and Their Electrochromic PropertiesChinese Journal of Polymer Science - Tập 39 - Trang 147-153 - 2020

Direct arylation methods have been used to polymerize thienylmethylene oxindoles (TEIs) and 3,3-bis[[(2-ethylhexyl)oxy]methyl]-3,4-dihydro-2H-thieno-[3,4-b][1,4]dioxepin (ProDOT) for new donor-acceptor conjugated polymers. The polymers exhibited blue hues in neutral-state with distinct color-to-transmissive reversible electrochromic switching under applied potentials from 0 V to +1.5 V, and showed...... hiện toàn bộ
