Embodiment 1

[0014] (1) Dissolve 1g of lithium fluoride (LiF) in dilute hydrochloric acid (HCl) solution and stir thoroughly, and mix 1g of carbon titanium aluminum (Ti 3 AlC 2 ) powder was slowly added to the above solution, and reacted in a water bath at 35°C for 26h. The reacted solution was repeatedly washed with water and centrifuged until the pH of the solution was >6, the precipitate was collected and 100 mL of deionized water was added, and the solution was sonicated in an ice-water bath under an argon atmosphere for 1 h. Then the above solution was centrifuged to collect the supernatant, and the supernatant was freeze-dried to obtain etched titanium carbide (MXene). The etched titanium carbide was sonicated in an ice-water bath for 1 hour to form a 10 mg / mL aqueous solution;

Abstract

The invention provides a preparation method and application of novel adhesive and high-electrical-conductivity hydrogel. The hydrogel material with electrical conductive and adhesive properties is prepared through a polymerization method, and the hydrogel has good adhesive properties and mechanical properties and has high adhesive properties and mechanical strength on the surfaces of different materials such as metals, skin tissues and the like; and the hydrogel has high specific conductance and excellent electrical conductivity, can be used as a novel defibrillator electrode plate diaphragm material, is applied between human skin and a defibrillator electrode plate, and has the effects of adhesion, rapid reduction of contact impedance between an electrode and the skin and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to the preparation of a multifunctional hydrogel with adhesion and high conductivity and its application in the electrode plate diaphragm material of a defibrillator. Background technique [0002] The defibrillator is a medical device that quickly restores the heart rate. It is an essential first-aid equipment in the operating room. Pole and repolarization at the same time, so that the heart can recover organized and coordinated contraction, but high-intensity voltage will cause myocardial damage and skin burns and other diseases, and at the same time will greatly shorten the service life of the defibrillator electrode plate . At this stage, when using a defibrillator, it is necessary to apply medical conductive paste on the patient. The medical conductive paste can not only increase the conductive contact area of ​​the electrode plate, quickly reduce the cont...
