23 Jul Surface modification method of flexible stretchable circuit and application thereof
Abstract
The invention provides a surface modification method of a flexible stretchable circuit and an application thereof. According to the method, the cell compatibility and tissue compatibility of the conductive circuit and the circuit stability of the conductive circuit when being directly contacted with cells/tissues can be obviously improved, and the conductivity can still be well maintained after long-term co-culture or implantation in vivo; and the Faraday cage effect caused by a surface oxide layer is overcome, a stable electric field can be generated by serving as an electrode, and the functionality of conductive circuit is improved. The method is simple and convenient in step, easy to operate, capable of performing surface treatment without a need of special instruments and used for preparing functional flexible circuits in a large scale; the flexible stretchable circuit subjected to direct surface modification or multiple surface modification can be widely applied to a conductive circuit which is directly contacted or indirectly contacted with cells or tissues and applied to the fields such as tissue engineering, biosensors and photoelectric materials; and the method can quicklyrealize industrial large-scale preparation and applied to the fields such as wearable electronic equipment and implantation medical instruments.
