对烷基胺-乙二醇有机凝胶的粘弹性进行了系统的流变学研究。微观结构和由此产生的机械性能,从而研究在温度,链长和浓度的烷基胺的功能。采用基于剪切弹性与浓度的标度律的模型来描述凝胶的结构特征。根据过饱和原理,当烷基胺的链长从12增加到18时,可以解释从层状/纤维状到球晶/多面体网络的逐渐结构变化。
A systematic rheological study is undertaken to investigate the viscoelastic behaviors of alkylamine-ethylene glycol organogels. Microstructures and resulting mechanical properties are thus studied in the functions of temperature, chain length and concentration of the alkylamine. A model based on scaling laws of shear elasticity versus concentration is employed to describe the structural features of the gels. According to the supersaturation principle, a gradual structural change from lamellar/fibrillar to spherulitic/polyhedral network can be accounted when the chain length of alkylamine is increased from 12 to 18.
