MPAE conductive composite hydrogel as well as preparation method and application thereof

The invention provides MPAE conductive composite hydrogel as well as a preparation method and application thereof, and belongs to the technical field of composite materials and sensors. According to the preparation method, firstly, LiF powder and Ti3AlC2 powder react in HCl to prepare an Mxene material, and then the Mxene material, polyvinyl alcohol and polyacrylamide are used for preparing MPAE conductive composite hydrogel; the MPAE conductive composite hydrogel takes a three-dimensional network structure constructed by polyvinyl alcohol and polyacrylamide as a main body, wherein MXene nanosheets are uniformly dispersed in a fish scale shape; the MXene material is of a multi-layer sheet structure, and the whole MXene material is in an accordion shape. The MPAE conductive composite hydrogel has good application in the preparation of a piezoresistive flexible sensor. 本发明提供了一种MPAE导电复合水凝胶及其制备方法和应用，属于复合材料和传感器技术领域；本发明中首先将LiF粉末和Ti3AlC2粉末在HCl中反应制备了Mxene材料，然后利用Mxene材料、聚乙烯醇和聚丙烯酰胺制备了MPAE导电复合水凝胶；所述MPAE导电复合水凝胶以聚乙烯醇和聚丙烯酰
