Advances in preparation and applications of laser-induced graphene made from biomass materials
As an emerging two-dimensional nanostructure material,graphene is widely used in various fields due to its unique physical structure and chemical properties.The traditional graphene preparation process has certain technical difficulties,including relatively expensive equipment,poor control of the shape of the product,and the presence of oxygen-containing functional groups in end products.It also has drawbacks such as high required temperature for the reaction conditions and long synthesis routes,which limit its applications in practical production.With high laser ener-gy density and controllability,laser-induced graphene technology can prepare graphene materials from carbon contai-ning biomass materials that are widely available in nature in a low-cost,environmentally friendly,and fast recycle way.Firstly,the types of biomass materials that can be used for laser-induced graphene are summarized,and the methods and process characteristics of different biomass materials for preparation of laser-induced graphene are ana-lyzed and compared.Secondly,the application fields of laser-induced graphene and its performance characteristics are described in detail,and the development trend of the laser-induced graphene is summarized and discussed.The results of literature analysis show that the laser-induced technology is suitable for the preparation of graphene from a variety of biomass precursors,and through the optimization and combination of preparation conditions(gas environment,laser light source,and material pretreatment),it can realize the directional induced modification of biomass materials.Laser-induced graphene has good antibacterial,electrical properties,specific electrical resistivity and other pleasant characteristics,and the laser-induced technology has the advantages of high efficiency,simple process,low cost,con-trollable pattern,etc.It has demonstrated a great value of application in the fields of antimicrobial,smart home sys-tem,supercapacitor,and sensors with a good prospect for application.By reviewing the related research in the field of laser-induced graphene,this study can offer theoretical guidance for the innovation of graphene preparation technology,and provide ideas for expanding the research and application in this field.
