106. Nanostructures and Surface Hydrophobilicity of Self-assembled Thermosets involving Epoxy Resin and Poly(2,2,2-trifluoroethyl acrylate)-block-poly(ethylene oxide) Amphiphilic Diblock Copolymer. F.P.Yi, S.X.Zheng, T.X.Liu. J. Phys. Chem. B, 113(7), 1857-1868, 2009.
Poly(2,2,2-trifluoroethyl acrylate)-block-poly(ethylene oxide) (PTFEA-b-PEO) amphiphilic diblock copolymer was synthesized via the reversible addition-fragmentation transfer polymerization of 2,2,2-triffluroethyl acrylate with dithiobenzoyl-terminated poly(ethylene oxide) as a chain-transfer agent. The amphiphilic diblock copolymer was incorporated into epoxy resin to prepare the nanostructured ep...

43. Effect of heat treatment on the parameters of crystal structure and degree of crystallinity of poly(aryl-ether-ether-ketone). Liu TX, et al. CHEM. J. CHIN. UNIV.-CHINESE 17 (7): 1142-1146, 1996.
The variations of unit cell parameters and crystallite size of nine PEEK samples treated at various temperatures have been studied by using Wide-Angle X-ray Diffraction (WAXD), The results indicate a decrease in unit cell parameter a,b and c but an increase in crystallite size L(hkl) With the increase beat treatment temperature. Based on X-ray scattering intensity theory and using the graphic mult...

38. The crystal structure and drawing-induced polymorphism in poly(aryl ether ketone)s. 2.Poly(ether ether ketone ketone),PEEKK. Wang SG, Wang JZ, Liu TX,et al. MACROMOL.CHEM.PHYS.198(4):969-982,1997.
The crystal structure, morphology and polymorphism induced by uniaxial drawing of poly(ether ether ketone ketone) [PEEKK] have been studied by transmission electron microscopy (TEM), electron diffraction (ED) and wide angle X-ray diffraction (WAXD). On the basis of WAXD and ED patterns,the crystal structure of unoriented PEEKK is determined to have two-chain orthorhombic packing with unit cell par...

24. Bulk viscosity and its unstable behavior upon storage in polyimide precursor solutions. Tong YJ, Liu TX, Veeramani S, Chung TS. IND. & ENG. CHEM. RES. 41 (17): 4266-4272, 2002.
The bulk viscosity behavior of poly(amic acid) and its amine salt solutions, PAA(ODPA/o-tolidine) and PAS(ODPA/o-tolidine), has been investigated. Both PAA(ODPA/o-tolidine) and PAS(ODPA/o-tolidine) solutions show strong concentration and molecular weight dependence on bulk viscosity, and display critical values on the concentration dependence of bulk viscosity because of increasing the molecular c...

南科大蒋伟教授课题组Nat. Chem.：剪切力诱导组装瞬态高度可拉伸水凝胶
关键字：可拉伸，水凝胶，剪切诱导
分子的自组装是生物系统中最常见的一种现象，能够实现多功能结构的构筑，从而应对复杂的外部环境。通过向大自然学校，科学家们利用分子之间的相互作用力能够实现分子之间的自组装，然而人工实现的分子自组装体大多为热力学平衡态下的产物。实际生命体中的分子自组装则多是在需要外界能量如光、电、磁等的驱动下完成的，是一种需要消耗能量的耗散自组装（Dissipative self-assembly），通过能量的消耗来维持非平衡态...
