Formaldehyde adsorption composite paper with nacre-inspired structure and high mechanical strength properties

With the increasing attention of indoor air pollutant, high adsorption performance materials are widely used to deal with formaldehyde. However, the mechanical properties and adsorption efficiency usually limited their applications. In this study, amine-functionalized graphene/fiber composite paper with nacre-inspired structure and high mechanical strength is fabricated through vacuum filtration-induced self-assembly process via a environmentally friendly synthesis route. By the interaction between amine-functional graphene oxide and pine pulp fiber, the formaldehyde adsorption composite paper has been successfully achieved, having high mechanical properties for tensile strength, tear strength and elongation and good adsorption performance. The good physical and adsorption performance of our composite paper provides a new insight into the design and fabrication of advanced photocatalytic materials.
