Abstract
(EN)
Disclosed are an MXene/metal composite aerogel, a preparation method therefor and use thereof, and a thermal interface material containing same. The MXene/metal composite aerogel comprises an MXene framework and a metal. The MXene framework is cross-linked by means of the metal to form a network structure. The MXene/metal composite aerogel is prepared by means of a method, comprising: first reacting MXene with a metal salt, reducing metal ions into metal nanoparticles in situ, then forming the network structure by using an ice template method and freeze-drying, and finally annealing so that the metal nanoparticles are melted for "welding" to an MXene sheet layer. The MXene/metal composite aerogel provided in the present application has a good thermal conductivity, structural stability, and thermal conducting stability, and can be used as a thermal conducting filler and used for preparing the thermal interface material. The MXene/metal composite aerogel has good compatibility with an organic polymer material, and has a wider range of applications for a polymer substrate.

Sont divulgués un aérogel composite de MXène/métal, son procédé de préparation et son utilisation, ainsi qu'un matériau d'interface thermique le contenant. L'aérogel composite de MXène/métal comprend une structure de MXène et un métal. La structure de MXène est réticulée au moyen du métal pour former une structure de réseau. L'aérogel composite de MXène/métal est préparé au moyen d'un procédé, comprenant : tout d'abord la réaction du MXène avec un sel métallique, la réduction des ions métalliques en nanoparticules métalliques in situ, puis la formation de la structure de réseau à l'aide d'un procédé de modèle de glace et de lyophilisation, et enfin le recuit de telle sorte que les nanoparticules métalliques sont fondues pour le « soudage » sur une couche de feuille de MXène. L'aérogel composite de MXène/métal selon la présente invention présente une bonne conductivité thermique, une stabilité structurale et une stabilité de conduction thermique, et peut être utilisée en tant que charge thermoconductrice et pour préparer le matériau d'interface thermique. L'aérogel composite de MXène/métal a une bonne compatibilité avec un matériau polymère organique et présente une plus large gamme d'applications pour un substrat polymère.
