Abstract

A preparation method of bacterial cellulose-based power generation fiber, the bacterial cellulose superfine fiber strip is subjected to metal gold, silver, copper, aluminum and other vacuum sputtering coatings, and then metal zinc vacuum sputtering or evaporation treatment is carried out to obtain Bacterial cellulose B, take it out for use; put bacterial cellulose B into amine salt solution, react for a period of time to form bacterial cellulose C; carry out metallization and conductive treatment on bacterial cellulose C; prepare bacterial cellulose with power generation performance fiber. The finished product made by the method of the invention is the bacterial cellulose-based power generation fiber and yarn, which can be further processed through the existing weaving and weaving technology. The formation of mechanical power generation components of different scales is widely used in fields such as environmental monitoring, implantation of biochips in the body, automobiles, construction, military, etc., which have different size and power requirements for self-generating components.

Description

technical field [0001] The invention relates to a preparation method of bacterial cellulose-based power-generating fibers and yarns, in particular to a preparation method of bacterial cellulose-based power-generating fibers and yarns that can be applied to self-generating power sources of miniature and high-performance electronic devices and sensors. Background technique [0002] With the development of economy and society, electricity has become an indispensable part of society. The current situation of electricity in our country is lack of electricity in cities, remote areas without electricity, valleys in spring and autumn, and peaks in winter and summer. Although the country has started the west-to-east power transmission project, the power loss of long-distance power transmission and the high cost of laying lines have made the cost of power rise instead of falling. According to data released by the China Electricity Council, my country's electricity consumption reached...
