摘要

碳点因其典型的量子尺寸、优异的光学吸收与转换性质、良好的分散性和环保无毒等优点而备受关注。目前碳点的制备主要包括自上而下技术（如激光蚀刻法）和自下而上技术（如微波合成法、热裂解法和水热法）两类。其中，水热法制备碳点兼具原料来源广泛、制备方法简便、水分散性优异和表面易于功能化等优点，成为当前荧光碳纳米材料主流制备方法之一。综述归纳碳点主要制备方法、基本性质与形成机制，以及其在光催化、耐光老化、阻燃防火、抗菌和改性胶黏剂等木质功能材料领域的应用，并对碳点在新型木质功能材料研发方面的未来发展进行展望。

Abstract

Carbon dots have attracted significant attention due to their unique quantum size effect

excellent optical absorption and conversion properties

good dispersibility

and eco-friendly and non-toxic characteristics. The synthesis of carbon dots is generally categorized into top-down approaches (e.g.

laser ablation) and bottom-up methods (e.g.

microwave synthesis

pyrolysis

and hydrothermal treatment). Among these methods

hydrothermal treatment stands out for its adaptability to broad raw material sources

simple preparation process

excellent water dispersibility

and facile surface functionalization

making it one of the mainstream methods for preparing fluorescent carbon nanomaterials. This review summarizes the main preparation methods

basic properties

and formation mechanisms of fluorescent carbon dots

as well as their applications in the fields of wood-based functional materials such as photocatalysis

photoaging resistance

flame retardancy

antibacterial performance and adhesives. The prospects for the development of carbon dots in novel wood-based functional materials are also proposed.
