Abstract

The invention discloses a self-supporting disordered graphite carbon / carbon nanotube composite spring and a preparation method and application thereof. The preparation method comprises the following steps that carbon nanotube fibers are uniformly and orderly wound on a template with a thread structure; and a chemical vapor deposition method is adopted to perform amorphous graphite carbon deposition on the obtained spiral carbon nanotube fibers wound on the template, so that the self-supporting disordered graphite carbon / carbon nanotube composite spring with a spiral spring structure is obtained. According to the preparation method, the self-supporting disordered graphite carbon / carbon nanotube composite spring is successfully prepared by utilizing the chemical vapor deposition method and inducing configuration through the template, and the prepared composite spring has very good structural stability; and meanwhile, the preparation method provided is simple to operate and high in repeatability, and the size regulation and control of the light full-carbon spring spiral structure can be realized.

Description

technical field

[0001] The invention belongs to the technical field of composite materials, and in particular relates to a self-supporting disordered graphite carbon / carbon nanotube composite spring and its preparation method and application. Background technique

[0002] Wearable devices are an important development trend of future electronic equipment. In recent years, with the concept of electronic skin, flexible mobile phone, etc., and the continuous deepening of research, new (such as flexible, stretchable, bendable, etc.) energy storage and supply units and strain sensors compatible with living organisms quickly gained attention. Carbon nanotubes (CNTs) have quasi-one-dimensional properties and excellent electrical, thermal and mechanical properties. Their macroscopic aggregates---fibers are inherently lightweight, flexible, stretchable, and bendable. They are ideal for preparing wearables. It is an ideal material for functional devices, and it has broad application ...
