Flexible conductive film and preparation method thereof

Abstract

The invention provides a flexible conductive film and a preparation method thereof and belongs to the technical field of a conductive film. The conductive film comprises a prestretching elastic substrate, an elastic connection body and a nano lead, wherein the elastic connection body is arranged between the prestretching elastic substrate and the nano lead, the prestretching elastic substrate and the elastic connection body contact to form a bonding surface, a part of the material of the elastic connection body is embedded into the nano lead to form a hybrid transition region to enhance bonding performance. The flexible conductive film is advantaged in that the elastic material and the nano material are utilized, the prestretching process is utilized for preparation, excellent flexibility is realized, stable conduction characteristics can be kept under the stretching and torsion state, and the conductive film can be widely applied to complex or dynamic electronic skin surfaces in the robot, human body, clothes and medical equipment fields and can be further applied to touch screens, displays, film solar energy cells and organic light emitting diodes having special flexibility requirements.

Description

technical field [0001] The invention relates to the technical field of conductive films, in particular to a flexible and elastic conductive film and a preparation method thereof. Background technique [0002] Electronic skin is the most important wearable device that can cover complex or dynamic surfaces such as intelligent robots, human bodies, clothing, medical equipment, etc., to realize the sensing and perception of intelligent manufacturing and robots, and to ensure the safety of human-machine integration One, it has the characteristics of lightness, flexibility, and elasticity, and can be freely bent, stretched, and twisted without losing its normal functions. The flexible and elastic conductive film as the electrode layer is not only an important part of electronic skin, but also an important part of touch screens, displays, thin-film solar cells, organic light-emitting diodes, etc. that have special requirements for flexibility. [0003] At present, the conductive f...
