Abstract

The invention discloses a fiber capacitor and a preparation method thereof. The preparation method comprises the steps of: (1) depositing a first conductive fiber membrane on a yarn surface by an electrostatic spinning technology; (2) coating the outside of the first conductive fiber membrane with an insulating layer by a hollow ingot wrapping spinning technology; (3) repeating the step (1) and depositing a second conductive fiber membrane outside the insulating layer; and (4) repeating the step (2) and coating the outside of the second conductive fiber membrane with an outer insulating layer. The preparation method of the fiber capacitor is simple and convenient; the production cost is low; and extensive popularization and application are facilitated.

Description

technical field [0001] The invention relates to the field of production and preparation of polymer fiber materials, in particular to a fiber capacitor and a preparation method thereof. Background technique [0002] Smart clothing with wearable electronics has quickly turned from fantasy to reality and will usher in a new electronic age. In the process of realizing smart clothing of wearable electronic devices, flexible devices for wearable energy conversion and storage have become an important issue restricting the continued development of this generation of electronic products. However, current flexible devices are mainly based on planar flexible electrodes, which are assembled into flexible devices through stacking. Using this structure makes the prepared garments not breathable, and the integration into wearable garments makes the garments less comfortable. Focusing on this problem, Wei Zhixiang's research group at the National Center for Nanoscience and Technology, in ...
