内容摘要

Graphene has attracted a tremendous amount of attention and research focus since it was successfully exfoliated from highly oriented pyrolytic graphite (HOPG) in 2004. The exceptional properties of graphene, such as ultra-high electrical conductivity, excellent thermal stability, and outstanding mechanical properties make it a promising material for many potential applications, including next generation ultra-compact computers, flat screen displays, sensors, solar cells, conducting plastics or ceramics, micro-electro-mechanical devices and novel protection coatings. Numerous synthesizing approaches have been developed to growth good quality graphene with specific advantages and disadvantages. It is strategically important and great need to explore a comprehensive approach, which integrates several merits including large-area growth, patterned growth and fast growth of graphene for practical applications. 
In this work, we report an engineering approach to grow graphene via high power laser rapidly for large area or for designable pattern. The high power and continuous-wave diode laser and fiber laser were employed to irradiate solid carbon source coated on nickel substrate surfaces in ambient condition. Graphene was synthesized by carbon dissolution into the substrate during rapid laser heating and then precipitated onto surface during rapid cooling. The graphene growth rate by this laser approach can reach up to 28.8 cm2/min. Large area graphene was fabricated by a rectangular diode laser beam via a single pass. Any designable pattern of graphene can be available by a focused fiber laser beam. In addition to the above merits, the solid carbon source is less hazardous compared to typical gaseous carbon sources used in CVD. The influence of laser and process parameters on the graphene formation and quality was investigated systematically. Raman analyses, optical images and scanning electron microscopy (SEM) results indicate that the quality of graphene strongly depends on the laser process parameters, including laser power density and scanning rate. These parameters have been optimized to control the heat input and then the quality of graphene. The penetration and precipitation mechanism of carbon into Ni substrate during the fabrication process were also discussed. The corrosion resistance of this laser grown graphene in various condition was performed and compared to CVD grown graphene. This approach show good potential for applications.
