Abstract

The invention discloses a preparation method of polyaniline coated silver-loaded nano microcrystalline cellulose-based conductive ink. The preparation method modifies a nano microcrystalline cellulosesolution by adding a silver nitrate solution and sodium borohydride into the nano microcrystalline cellulose solution to obtain silver-loaded nano microcrystalline cellulose-based conductive particles, and then prepares the polyaniline coated silver-loaded nano microcrystalline cellulose-based conductive ink based on the silver-loaded nano microcrystalline cellulose-based conductive particles, which can greatly improve the performance of the conductive ink. The invention provides the novel silver conductive ink which has good chemical stability and is not prone to oxidation, improves the electrical performance of the silver conductive ink, and reduces the production cost.

Description

technical field [0001] The invention relates to a preparation method of polyaniline-wrapped silver-loaded nano-microcrystalline cellulose-based conductive ink, which belongs to the field of conductive material preparation. Background technique [0002] In recent years, with the intensification of environmental problems, renewable resources have become an inevitable choice for people. Cellulose is the most abundant carbohydrate on earth. It is a natural polymer material synthesized by plants through photosynthesis. It widely exists in plants, animals and bacteria, so it has become the focus of researchers. Nanocrystalline cellulose not only has the characteristics of cellulose, but also has other characteristics through a series of modifications. There are also many studies on nanocrystalline cellulose. From the preparation, modification and application of nanocrystalline cellulose, the research on nanocrystalline cellulose is gradually becoming mature. As a hotspot in the ...
