Corn stalk is a kind of biomass material rich in cellulose, hemicellulose and lignin, which has excellent comprehensive mechanical properties. In recent years, great progress has been made in the research on the comprehensive utilization of corn stalk, especially as biomass functional materials. Its application in construction, industry,agriculture, environmental protection, food and other fields has promoted the rapid development of corn stalk material research. On the basis of summarizing the characteristics of corn stalk materials, this paper focuses on its latest research and development progress in building materials, adsorption materials, packaging and papermaking materials and battery materials, and puts forward the prospects for the problems and development direction of the application of corn stalk materials.
