摘要： A method of preparing an electrode material includes heating a substrate with a bonding agent to form a self-assembled monolayer-containing material; and depositing a polymer coating onto the self-assembled monolayer-containing material under an elevated temperature to form a layered material. An electrode material and an electrode incorporating the electrode material is also provided.
