Abstract

The invention discloses an ion sensor based on MXene electrodes, and relates to the technical field of flexible ion sensors. The invention includes an ion polymer film and two electrode layers containing MXene, and the ion polymer film is located between the two electrode layers containing MXene Meanwhile, the ionic polymer membrane is mainly made of ionic liquid and thermoplastic polyurethane. The present invention also includes the preparation method of the above-mentioned ion sensor. The beneficial effect of the present invention is that: the ion sensor in the present invention does not need electroplating metal electrodes, and can directly use the electrode layer containing MXene as an electrode.

Description

technical field [0001] The invention relates to the technical field of flexible ion sensors, in particular to an ion sensor based on MXene electrodes and a preparation method thereof. Background technique [0002] When the breeze blows across the water surface, obvious ripples can be seen on the water surface. When an object is immersed in the water, the water can easily change its shape to accommodate the foreign object. Molecules diffuse more easily in liquids than in solids, and thus can more easily sense external stimuli. When ions exist in the solution, they are easy to diffuse with the solution, so different electrical signals can be brought to a specific location to be identified. For example, all types of cells in biological systems can obtain information through ion exchange. The ion sensor is a sensing system based on ion transport, which contains ions that can move freely like liquid molecules, so it has a stronger ability to recognize dynamic tiny stimuli than o...
