对弹性体聚合物纳米复合材料不断发展的理解继续扩大商业，国防和工业产品和应用。本工作探讨了弹性体纳米复合材料的热机械性能的双酚A二缩水甘油醚和三个胺封端的聚（环氧丙烷）（Jeffamines）。研究的Jeffamines包括分子量为2000和4000 g mol-1的双官能交联剂和分子量为3000 g mol-1的三官能交联剂。另外，向每种热固性材料中添加至多1.25重量%的碳纳米管（CNT）。研究结果表明，聚合物纳米复合材料的Tg和储能模量可以独立地控制在狭窄的浓度窗口内，和观察到的效果后，CNT掺入依赖于交联剂的分子量。最后，交联剂的长度和架构，以及CNT除了在玻璃态和橡胶态的交联点之间的分子量的影响进行了讨论。
An evolving understanding of elastomeric polymer nanocomposites continues to expand commercial, defense, and industrial products and applications. This work explores the thermomechanical properties of elastomeric nanocomposites prepared from bisphenol A diglycidyl ether and three amine-terminated poly(propylene oxides) (Jeffamines). The Jeffamines investigated include difunctional crosslinkers with molecular weights of 2000 and 4000 g mol-1 and a trifunctional crosslinker with a molecular weight of 3000 g mol-1 . Additionally, carbon nanotubes (CNTs) are added, up to 1.25 wt%, to each thermoset. The findings indicate that the T g and storage modulus of the polymer nanocomposites can be controlled independently within narrow concentration windows, and that effects observed following CNT incorporation are dependent on the crosslinker molecular weight. Finally, the impact of crosslinker length and architecture as well as CNT addition on the molecular weight between crosslink points in the glassy and rubbery states are discussed.
