Carbon nano tube extensible electrode preparation method

Abstract

The invention provides a carbon nano tube extensible electrode preparation method. The method comprises the steps of mixing carbon nano tube solution with microsphere solution through a physical method to form mixed solution; obtaining a glass substrate, depositing the mixed solution on the glass substrate, standing and drying to form a mixture; adding liquid-state extensible material to the mixture, standing, curing and uncovering the mixture from the glass substrate to obtain a carbon nano tube extensible electrode. The carbon nano tube electrode prepared through the method disclosed by the invention has extremely-high reliability; from a conductive mechanism, a spatial net-shaped structure formed by the carbon nano tubes is a very effective construction method for a conductive network, and the network can guarantee that a conductive path is prevented from being damaged by a defect or breakage of some portion of a conductive material; from the perspective of material stability, carbon nano tubes have higher physical and chemical stability; meanwhile, as the outer surface of the conductive material is wrapped by the extensible material, the conductive material is better protected.

Description

technical field [0001] The invention relates to the field of stretchable electronic devices, in particular to a preparation method of a carbon nanotube stretchable electrode. Background technique [0002] For all electronic devices, electrodes are considered to be the most critical part, playing a great role in the process of signal generation, transmission and detection. Whether it is for traditional electronic devices or newly developed flexible and stretchable electronic devices, the performance of electrodes (conductivity, reliability, etc.) is particularly important. Research on flexible and stretchable electronic devices, such as electronic skin, stretchable light-emitting diodes, and stretchable actuators, has received increasing attention and attention. In the study of stretchable devices, conductive nanomaterials (conductive nanoparticles and nanowires, etc.) are widely used to prepare stretchable electrodes because they can maintain good electrical conductivity du...

AI Technical Summary

Problems solved by technology

[0003] The method of coating conductive nanomaterials on the surface of stretchable substrates to form a conductive network is widely used to prepare stretchable electrodes, but the electrodes prepared by this method are prone to adhesion and fall off, which greatly affects their reliability. One strategy is to directly mix conductive nanomaterials and stretchable materials to form stretchable electrodes after curing, but this method will seriously affect the mechanical properties of stretchable materials, such as Young's modulus, fracture limit, etc.
