SELF-ASSEMBLY OF CHEMICALLY MODIFIED GRAPHENE FOR ENERGY APPLICATIONS

摘要

Chemically modified graphene (CMG) has attracted a great deal of attention in recent years because of its unique two-dimensional structure, high electrical conductivity and electrochemical stability, excellent mechanical property and processibility. It has wide electrochemical applications in electrocatalysis, electrochemical sensors, actuators, and energy related systems. However, the sizes of CMG sheets are usually in the range of submicrometer to several micrometers. Furthermore, the restacking of graphene sheets usually greatly decreases the specific areas of electrode materials. The electrochemistry of graphene sheets have also not been revealed clearly. In this prezentation, we will describe the self-assembly of CMG sheets into macroscopic electrochemical materials with controlled microstructures. The applications of CMG materials in electrochemical biosensors, gas sensors, electrocatalysis, electrochemical actuators and electrochemical capacitors will be discussed.
