我们最近开发了一种新型的凝胶“滑动环（SR）凝胶”，基于由聚（乙二醇）的线状分子和α-环糊精（CD）分子的环组成的聚轮烷。SR凝胶具有移动的交联。为了改善独特的性能，即，利用SR凝胶的“滑动运动”或“滑轮效应”，通过甲基取代CD分子上的羟基，合成了甲基化聚轮烷，以抑制CD分子的自聚集倾向。用小角中子散射研究了甲基化CD分子的SR凝胶的结构。(c)2006 Elsevier B. V.保留所有权利。
We have recently developed a novel kind of gel "slide-ring (SR) gel", based on polyrotaxane consisting of thread-like molecules of poly(ethylene glycol) and rings of a-cyclodextrin (CD) molecules. The SR gel has mobile cross-links. In order to improve the unique properties, i.e., "sliding motion" or "pulley effect" of the SR gels and to suppress the self-aggregation tendency of CD molecules, methylated polyrotaxane was synthesized by substituting hydroxyl group with methyl group on CD molecules. The structure of SR gel having methylated CD molecules was investigated by small angle neutron scattering. (c) 2006 Elsevier B.V. All rights reserved.
