Research Progress in Preparation and Application of Fluorescent Composites Based on Nanocellulose and Carbon Quantum Dots
Carbon dot is a new type of zero-dimensional fluorescent nanomaterial with excellent optical properties,high thermal stability and chemical stability,which has been a research hotspot in recent years.Nanocellulose extracted from natural biomass has the characteristics of large specific surface area,environmental friendliness and biodegradability.The composite materials prepared by doped carbon dots with nanocellulose as the carrier have excellent fluorescence properties and mechanical properties,and have important application value.In this article,we first review the preparation and applica-tion of fluorescent composites based on nanocellulose and carbon dots,followed by a brief introduction to the properties and preparation of carbon dots.Then,we further discuss the preparation methods and related applications of nanocellulose-based fluorescent carbon dots hydrogel,films,aerogels and inks.Finally,we look forward to the development of fluorescent com-posites based on nanocellulose and carbon dots.
