摘要

研究了常规胶凝剂和不同类型的超分子胶凝剂对JP-10凝胶燃料流变性能的影响。利用不同浓度的1,2:5,6-二- o -异丙基-d -甘露醇（IPM）和1,2:5,6-二- o -环己基-d -甘露醇（CHM）超分子胶凝剂制备了基于JP-10的凝胶燃料，并与传统分子胶凝剂（Thixatrol ST (TST)）的凝胶燃料的流变特性进行了比较。流变学表征结果表明，所有类型的胶凝剂都可以在JP-10燃料中形成凝胶结构，包括胶凝剂浓度为1.0 wt%的tst基凝胶燃料，因为它们的tanδ值显著低于1。tst基凝胶燃料的tanδ值最低，因此具有最显著的固体样行为。然而，基于CHM凝胶的JP-10凝胶燃料的刚度值最高，而基于tst的JP-10凝胶燃料的刚度值最低。

Influence of conventional and supramolecular gellants on the rheological properties of JP-10 gel fuels

The effects of a conventional gellant and different types of supramolecular gellants on the rheological properties of JP-10 gel fuels are studied. Various concentrations of 1,2:5,6-di-O-isopropylidene-D-mannitol (IPM) and 1,2:5,6-di-O-cyclohexylidene-D-mannitol (CHM) supramolecular gellants are utilized for the preparation of JP-10 based gel fuels, and their rheological properties are compared with those of a conventional molecular gellant (Thixatrol ST (TST)) based gel fuel. Rheological characterization results show that all gellant types can create a gel structure within JP-10 fuel, including the TST-based gel fuel with a gellant concentration of 1.0 wt%, since their tanδ values are significantly lower than 1. The lowest tanδ values, hence the most significant solid-like behavior, were obtained for the TST-based gel fuels. However, the highest stiffness values were obtained for the CHM gellant-based JP-10 gel fuels, and the lowest stiffness values were obtained for the TST-based JP-10 gel fuels.
