Graphene-Based Sensors

Karim, Nazmul

Abstract

The present invention relates to a textile-based sensor which incorporates graphene into the fibre. The graphene is incorporated by a dyeing process in which a liquid composition containing the graphene is contacted with the fibre. The present invention thus also relates to a process for the preparation of a graphene-based yarn and the use of the resulting yarn in a variety of sensing applications. The graphene-based yarns of the invention may be derived from naturally occurring materials such as cotton or may be based on synthetic materials such as polyester, nylon, viscose, etc., or may be a blend of natural and synthetic materials. The present invention also relates to a screen-printed textile or a porous material, such as paper, printed on its surface with a 2D material such as graphene. This printed textile (fabric) has the 2D material incorporated by a screen-printing process in which a liquid or paste composition containing the 2D material is contacted with the textile or paper substrate. The present invention thus also relates to a process for the preparation of a graphene-or other 2D material-printed substrate and the use of the resulting printed substrate in a variety of applications such as wearable technology. The textiles of the invention may be derived from naturally occurring materials such as cotton or may be based on synthetic materials such as polyester, nylon, viscose, etc., or may be a blend of natural and synthetic materials.
