▎ 摘　　要

We prepared graphene yarn comprising reduced graphene oxide flakes and natural cellulose yam by simple dip coating and chemical reduction, and characterized its ultraviolet (UV) response under bending deformation. The as-prepared reduced graphene oxide cellulose yarns showed good basic properties including electrical conductivity (similar to 1.0 S/cm) and mechanical stability (1000 cycles), as well as a UV photoresponsivity of 1.31 mA/W (flat) and 1.0 mA/W (bent) and response times of 5 s/6 s (flat) and 6 s/7 s (bent). Our approach provides a path to realizing enhanced functional capabilities in natural cellulose textiles and their use in advanced smart textiles and wearable electronic/optoelectronic applications.
