Relaxation process and phase transition of lanthanide liquid crystalline complexes by photoacoustic spectroscopy李俊嘉,杨跃涛,刘晓峻,张淑仪,张仲宁摘 要:Lanthanide-containing liquid crystals exhibiting smectic A phase close to room temperature were obtained. Photoacoustic (PA) spectroscopy was used to study the spectral properties and phase transitions of liquid......
J. Cent. South Univ. (2020) 27: 1247-1261 DOI: https://doi.org/10.1007/s11771-020-4364-4 Ferrocenyl building block constructing porous organic polymer for gas capture and methyl violet adsorption...: Ferrocene-based porous organic polymer (FcPOP) was constructed with ferrocene and porphyrin derivatives as building blocks via Schiff-base coupling. FcPOP was well characterized, and exhibited good......
LiPF6 dissolved in EC/DEC/ DMC (m(EC)?m(DEC)?m(DMC)=1?1?1) for 10 min. The morphologies of polymer membrane were observed by using Japan JSM-6360LV scanning electron microscopy (SEM). The liquid... mechanical strength and can meet the requirement of polymer electrolyte used in commercial lithium batteries. After absorbing LiPF6 liquid electrolyte, the solution uptake of this polymer membrane......

Central South University Press and Springer-Verlag GmbH Germany, part of Springer Nature 2021 Abstract: The rational design of polymer acceptors with strong and broad absorption is critical to improve......
Numerical analysis of solid–liquid interface shape during largesize single crystalline silicon with Czochralski methodRan Teng1,2,Qing Chang1,Yang Li1,Bin Cui1,Qing-Hua Xiao1,Guo-Hu Zhang11. National... carried out to investigate the effect of crystal-crucible rotation and pulling rate on melt convection and solid–liquid(SL) interface shape. Through analyses of the simulation data, it is found......
the samples exhibit a relatively sharp endothermic peak at about 50 ℃, which can be attributed to the melting of the crystalline region of PEO. The crystallinity(Хc) of composite polymer electrolyte...; Abstract: Composite polymer......
molecule mass have been extensively studied[1]. Compared with their liquid counterparts, polymer electrolytes have advantages of longer shelf-life, better leak-proof capability, and easy fabrication...J. Cent. South Univ. Technol. (2008) 15: 438-442 DOI: 10.1007/s11771-008-0082-z Effect of catalyst on structure of (PEO)8LiClO4-SiO2 composite polymer electrolyte films PAN Chun-yue(潘春跃), ZHANG......
polymer networks LI Zhi-hua(李芝华), HUANG Yao-peng(黄耀鹏), REN Dong-yan(任冬燕), ZHENG Zi-qiao(郑子樵) (School of Materials Science and Engineering, Central South University, Changsha 410083, China) ..., 5-epoxycyclohexane-1, 2-dicarboxylate(TDE-85)/methyl tetrahydrophthalic anhydride (MeTHPA) epoxy resin was modified with polyurethane(PU) and the interpenetrating polymer networks(IPNs) of PU-modified......
and SEM we can observe the formation of semi-crystalline or polycrystalline phases of the inorganic polymer reaction products, and through the analysis of 27Al MAS-NMR we can understand... of crystalline peak. The reason for this is that in the early reaction, the inorganic polymer has the SiO4 structure with four oxygen atoms with highly crystalline characteristic, and as the age gets older......
-optical properties of polymer dispersed liquid crystal films CAO Hui, MENG Qingyong, SONG Ping, CHEN Hangping, YANG Zhou (School of Materials Science and Engineering, University of Science and Technology Beijing, Beijing 100083, China) Abstract: Polymer dispersed liquid crystal (PDLC) films were prepared from thermal polymerisation-induced phase separation in diglycidyl ether of bisphenol F (DGEBF......
