Facile fabrication of electrically conductive graphitic cellufoil for lighting and energy devices

A highly conductive flexible cellufoil composite was fabricated from cellulose nanofiber (CNF) and graphene nanoplatelets (GPs) through facile and low-cost papermaking process. The electrical conductivity and mechanical properties of cellufoil were highly dependent on cellulose to graphite ratio. The electrical conductivity of 219 S/m was found at CNF/GPs ratio of 1:25. While the enhancement of electrical conductivity of cellufoil was attained …
