The disclosure generally relates to a dispersion of nanoparticles in a liquid medium. The liquid medium is suitably water-based and further includes an ionic liquid-based stabilizer in the liquid medium to stabilize the dispersion of nanoparticles therein. The stabilizer can be polymeric or monomeric and generally includes a moiety with at least one quaternary ammonium cation from a corresponding ionic liquid. The dispersion suitably can be formed by shearing or otherwise mixing a mixture/combination of its components. The dispersions can be used to form nanoparticle composite films upon drying or otherwise removing the liquid medium carrier, with the stabilizer providing a nanoparticle binder in the composite film. The films can be formed on essentially any desired substrate and can impart improved electrical conductivity and/or thermal conductivity properties to the substrate.
                            本文涉及纳米颗粒在液态介质中的分散。液态介质适宜为
水基,并且在其中包含一种
离子液体基础的稳定剂以稳定纳米颗粒的分散。稳定剂可以是聚合物或单体,并且通常包括具有至少一个相应
离子液体中的季
铵阳离子的基团。该分散可以通过剪切或混合其组分的混合物/组合物而形成。干燥或去除液态介质载体后,可以使用这些分散物形成纳米颗粒复合膜,稳定剂在复合膜中提供纳米颗粒粘合剂。这些膜可以形成在任何所需的基底上,并且可以赋予基底改善的电导性和/或热导性能。
