Abstract

The invention discloses a foam type conductive colloidal skin-friendly dressing as well as a preparation method and application thereof, and relates to the technical field of conductive materials. The foam type conductive colloidal skin-friendly dressing is prepared from the following raw materials in parts by weight: 1 to 10 parts of polyvinyl alcohol, 1 to 10 parts of polyvinylpyrrolidone, 15 to 25 parts of polyethyleneimine, 1 to 5 parts of cross-linking agent, 1 to 5 parts of softener, 1 to 5 parts of stabilizer, 10 to 90 parts of water and 5 to 10 parts of conductive filler. Effective crosslinking is completed through reasonable proportion regulation and control, the skin-friendly foam type conductive adhesive with a pore channel structure is formed, the formed conductive adhesive is small in density and small in resistance, can meet the application requirement of a human body sensor electrode, and is non-toxic to skin, biodegradable and good in biocompatibility. The traditional Chinese medicine composition is free of irritation to skin, low in manufacturing cost and safe to use, and has a good economic effect. The method can be widely applied to preparation of a pipeline sealing anti-leakage agent, flexible medical electronic equipment, a sensor electrode or an auxiliary buffer electrode.

Description

technical field [0001] The invention relates to the technical field of conductive materials, in particular to a foam-type conductive gel skin-friendly dressing and a preparation method and application thereof. Background technique [0002] With the vigorous development of flexible electronics technology, stretchable and compressible electrical conductors with three-dimensional structures have received extensive attention and research in deformable electronics because of their special mechanical and electrical properties. Different from traditional metal conductors, flexible conductors are subjected to long-term stress and deformation during the preparation and use process, resulting in poor mechanical properties and low electrical conductivity, which ultimately cannot meet the stable performance requirements. In order to solve this technical problem, people began to study foamable conductive composite materials. According to CN113831652A (a carbon-based modified high-conduct...
