Embodiment 1

[0024] In the present invention, the crude arabinoxylan extract is firstly extracted from the psyllium seed husk by hot water extraction method, and the pure arabinoxylan product is obtained through repeated redissolving and deproteinization treatment by Sevage method. Prepare the arabinoxylan solution from the product, and dry it in a constant temperature and constant humidity drying box to form a transparent paper; mix the nano-conductive medium evenly with the commercial ink to form a conductive nano-ink, and print the conductive nano-ink directly on the surface of the arabinoxylan film Thus, transparent conductive paper was successfully prepared, and the specific steps are as follows:

Abstract

The invention discloses transparent conductive paper capable of being directly printed. The transparent conductive paper comprises transparent paper made of araboxylan and a conductive pattern formedby directly printing a conductive material on the transparent paper. According to the invention, the excellent film-forming property of araboxylan is utilized, and the conductive material is printed on the surface of the transparent paper in a direct printing manner, so that the transparent conductive paper is successfully prepared. The transparent conductive paper has high transparency and low surface roughness, the low surface roughness can effectively reduce the short-circuit probability of the conductive material, the stability of the conductive material can be improved, the transparent conductive paper can be used as a potential substitute of a petroleum-based transparent conductive base material, and a foundation is laid for printable preparation of transparent electronic elements. The araboxylan transparent conductive paper designed by the invention has no difference from common paper in the printing process, and has the advantages of simple operation, high repeatability and thelike.

Description

technical field [0001] The invention relates to the field of transparent conductive paper, in particular to a transparent conductive paper that can be directly printed. Background technique [0002] With the depletion of petroleum resources, the environmental pollution caused by petroleum-based chemicals is becoming more and more serious. Therefore, it is very important to develop a biodegradable and environmentally friendly material to alleviate the oil crisis and reduce the risk of environmental pollution. In addition, with the rapid development of the high-tech industry, the frequency of electronic product replacement is increasing year by year, and the environmental pollution caused by electronic product waste has become a major problem that needs to be solved urgently. The base materials of electronic products are mostly non-degradable materials such as petroleum-based chemicals, and the use of biodegradable biological resources (cellulose, hemicellulose, chitin, silk ...
