摘　　要：无溶剂纳米流体是由具有柔性链结构的有机长链分子通过离子键作用以足够高的接枝密度锚定在纳米粒子表面形成的具有类液体行为的纳米材料。它们最显著的特点是能够在室温条件下不借助任何溶剂就表现出液体的流动性。由于这类材料具有特定的离子键作用形式以及室温类液体特性,它们也被称为纳米尺度离子材料或超分子离子液体。由于这类材料能在无溶剂的条件下表现出类液体行为,它们还被称为自悬浮纳米粒子流体或干纳米流体。本文介绍了无溶剂纳米流体的微观结构、基本特性以及流动机理,并对无溶剂纳米流体中零维、一维、二维以及大分子纳米类流体的研究现状及应用进行了综述。Solvent-free nanofluids are generally referred to as the nanohybrids that consist of a rigid core and soft organic shell, where the shell is typically fabricated by grafting flexible charged organic oligomers to the surface of nanostructures. This novel gallery of hybrid material shows remarkable liuqid-like behavior in absence of any solvent at ambient temperature. With respects to the characteristic ionic bond that supports the core/shell building blocks, they can be regarded as nanoscale ionic materials or supermolecular ioni liquids. Meanwhile, the unique liquid manner also wins them the name of self-suspended nanoparticles and dry nanofluids. In this contribution, recent advances in researches on solvent- free nanofluids, including their microstructures, typical features and flowing mechanism along with the applications of O-2D and macromolecular nanofluids have been reviewed.
