Exploring coating technologies: A mini-review on traditional types and the revolutionary role of graphene

This mini-review provides an in-depth exploration of various coating technologies, including physical vapor deposition (PVD), chemical vapor deposition (CVD), micro-arc oxidation (MAO), sol-gel, and thermal spray coating. The working principle and advantages of these techniques are examined to highlight their roles in enhancing material properties and performance across multiple industries. The review then shifts to the revolutionary potential of graphene as a coating material. The unique combination of exceptional mechanical strength, electrical, thermal conductivity, and chemical stability makes graphene a superior coating material. By establishing coating technologies with the innovative applications of graphene, this mini-review highlights the transformative impact of graphene on anti-corrosion and anti-microbial coating applications.
