Title:
GRAPHENE FIBER NON-WOVEN FABRIC AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/014583
Kind Code:
A1
Abstract:
Disclosed are a graphene fiber non-woven fabric and a preparation method therefor. The non-woven fabric is obtained by filtering and depositing a dispersion of graphene short fibers through a filter net and drying and reducing same, so that the structural unit of the non-woven fabric is graphene short fibers that are stacked in a disorderly manner and bonded to each other, and the fibers are overlapped to form a large number of holes through which a liquid or a gas can pass. The graphene fiber non-woven fabric has a relatively good mechanical strength and tenacity, and is completely composed of graphene fibers, and does not contain a high-molecular material as a skeleton or an adhesive, etc. The electricity and heat conducting performances of a network structure formed by overlapping the graphene fibers and being reduced are excellent. The non-woven fabric can be used as a multifunctional high-performance fabric.
