Abstract

Formation and properties of epoxy nanocomposites with carbon (nanotubes, graphene, and graphite) fillers are considered. In contrast to linear polymers, epoxy nanocomposites are obtained only via curing of epoxy oligomers in the presence of filler. These additives may affect the kinetics of the formation and the properties of resulting matrix. High reactivity of epoxy groups and thermodynamic miscibility of epoxy oligomers with many substances make it possible to use diverse curing agents and to accomplish curing reactions under various technological conditions. The mutual effect of both a matrix and nanoparticles on the composite formation and structure is discussed. Special attention is paid to the structure of epoxy nanocomposites and the interphase layers in these systems. The questions of the percolation threshold and its dependence on the dimension and orientation of nanoparticles are considered. The data on the mechanical and tribological properties of epoxy nanocomposites are summarized. Problems and prospects of development of nanocomposites based on epoxy polymers and nanofillers are considered.

具有碳填料的环氧树脂纳米复合材料

摘要

考虑了具有碳（纳米管、石墨烯和石墨）填料的环氧纳米复合材料的形成和性质。与线性聚合物相比，环氧纳米复合材料仅通过在填料存在下固化环氧低聚物而获得。这些添加剂可能会影响形成的动力学和所得基质的性质。环氧基团的高反应性和环氧低聚物与多种物质的热力学混溶性使得可以使用多种固化剂并在各种工艺条件下完成固化反应。讨论了基体和纳米粒子对复合材料形成和结构的相互影响。特别注意环氧纳米复合材料的结构和这些系统中的界面层。考虑了渗透阈值及其对纳米粒子尺寸和取向的依赖性的问题。总结了环氧纳米复合材料的机械和摩擦学性能数据。探讨了基于环氧聚合物和纳米填料的纳米复合材料的发展问题和前景.
