Abstract

The invention relates to a flexible electrode based on a flower-like nanogold structure and a preparation method thereof, and belongs to the technical field of electronic materials. The flexible electrode is characterized in that ITO (Indium Tin Oxide) glass is self-assembled layer by layer, electrochemical gold deposition is carried out on the assembled ITO glass by adopting chronoamperometry, alayer of golden flower-like nanogold will deposit on the ITO glass after the electrochemical deposition, and the golden flower-like nanogold depositing on the ITO glass is called ITO-Au; used electrolyte is a KAuCl4 and H2SO4 mixed solution, a reference electrode is an Ag / AgCl electrode, a counter electrode is a platinum wire, and a working electrode is the assembled ITO glass; the ITO glass requires to be cleaned before assembling. A cleaning process is characterized by carrying out ultrasonic cleaning by respectively using deionized water, acetone and ethanol. The flexible electrode preparedby the invention has lower square resistance, and good electrical conductivity still can be kept after bending for many times and stretching for many times.

Description

technical field [0001] The invention relates to the technical field of electronic materials, in particular to a flexible electrode based on a flower-like nano-gold structure and a preparation method thereof. Background technique [0002] With the development of electronic information technology, electronic equipment and electronic devices are developing in the direction of integration, portability, miniaturization and flexibility. In order to meet the development needs of electronic technology, it is very necessary to prepare novel electrodes with flexible and stretchable functions. Traditionally, tin-lead-copper and other metal solders are often used as conductors to realize the conductive interconnection of electronic components. However, with the demand for lightness and flexibility of electronic devices and the environmental protection requirements of lead-free, metal solders have high processing temperature and high hardness. , lead pollution and other shortcomings are...
