Problems solved by technology

On the other hand, flexible matrix conductive material printing technology has developed rapidly in recent years, but this technology can only obtain a single conductive material (such as gold powder, silver-based conductive ink, carbon-based conductive ink, etc.) Sub-composite circuit (the composition of each section of the wire is different), it is necessary to replace the nozzle and other operations several times

Abstract

The invention relates to a paper-based compound three-dimensional macro / nano circuit and a processing method thereof. Macro / nano manufacturing, paper pulp molding and nano conducting ink are combined,a processing three-dimensional paper-based network structure is filled with conducting nano particles, and the circuit is constructed. Through filling of the multi-component conducting nano particles, the composite material circuit can be obtained. The processing technology has the advantages that processing is simple, materials are environmentally friendly, and the cost is low, and is new application of a microfluidic technology in flexible circuits.

Description

technical field [0001] The invention relates to the field of paper-based microfluidic chips, in particular to a paper-based composite three-dimensional micro / nano circuit and a processing method thereof. Background technique [0002] Paper-based microfluidic chip is a new type of fluid manipulation and analysis system, which can realize the self-driving of fluid by means of capillary action, and can easily manipulate micro / nano-level liquids in a very small space, which promotes the development of portable analysis technology. Paper has attracted widespread attention because of its easy access, low cost, large specific surface area, and its advantages of being able to transport fluid samples such as blood and buffer solutions and biochemical reagents without external equipment. Existing paper-based microfluidic chip processing methods include ultraviolet lithography, laser cutting, wax jet printing, inkjet printing, inkjet solvent etching, etc. The processing objects are mos...
