Contribution of reduced graphene oxidetohemicelluloses-basedfilms with enhanced mechanical and conductivity properties

Abstract

Aquaternized hemicellulose (QH)/chitosan/reduced graphene oxide (rGO) composite film with good mechanical propertyand electrical conductivity was prepared bysolution-casting method. The effects of reduced graphene oxide contents on the structures and properties of the composite films were investigated.The mechanical property and electrical conductivity of the film with rGO containing 0.5 wt.% was reached 102.09 MPa and 12.8 × 10− 2 S/cm, respectively.Under the functions of hydrogen bonds and Van Der Waals forces, three components were combined to obtain QH/CS/rGO composite films with higher thermal stability and conductivity. Due to the compositing of rGO, the composite films showed good UV-blocking properties.This work provided a low-cost and sustainable pathway for the application of high-strength hemicellulose composite films with electrical conductivity and UV resistance in flexible electrode materials.
