Ionic mechanical sensor based on MXene/Ag composite structure material and preparation method and application thereof

The invention discloses an ionic mechanical sensor based on an MXene/Ag composite structure material. The ionic mechanical sensor comprises a composite layer formed by MXene/Ag electrode layers on the two sides and an ionic liquid polymer middle layer. The invention also discloses a preparation method of the ionic mechanical sensor. The preparation method comprises the following steps: preparing the ionic polymer layer; preparing the electrode layer of the MXene/Ag composite structure material; and carrying out hot pressing on the composite film to obtain the ionic mechanical sensor with a three-layer structure. The invention also discloses an application of the ionic mechanical sensor made of the MXene/Ag composite structure material. Compared with a traditional ionic mechanical sensor, the ionic mechanical sensor disclosed by the invention uses the MXene material with the two-dimensional layered structure, and the structure of the ionic mechanical sensor is beneficial to transmission and storage of ions.
