摘要
透明木材因其制备简单、绿色环保、高强高韧以及高透光、高雾度的特殊性质而备受人们关注,在光电器件、绿色照明、节能建材等领域具有广阔的应用前景。近年来,一些学者通过向透明木材中负载发光物质得到一种具有光响应发光特性的新型木质基复合材料,成功拓展了透明木材在光学领域的应用范围,有助于木材的高赋值、可持续发展,对我国“双碳”战略的实施起到一定促进作用。文中从透明木材的透光原理出发,着重介绍了光响应型发光透明木材的响应机制、制备过程和相关应用;同时指出,未来研究应主要集中在对碳点发光机理的研究、聚合物协同作用的深化以及大尺寸制备工艺的探索上,以期为光响应型发光透明木材的工业化发展提供思路。
Transparent wood has garnered a lot of interest owing to its advantages and special properties like easy preparation,eco-environmental friendliness,high strength,high toughness,high transmittance and high haze,and it has broad application potential especially in photoelectric devices,environmentally friendly lighting and energy-efficient construction materials.By adding luminescent materials to transparent wood,some researchers have recently created a new type of wood-based composite with the photo-responsive luminescence properties,which has successfully expanded the range of applications for transparent wood in the field of optics,contributed to the value-added and sustainable development of wood,and promoting the implementation of China’s“Double Carbon”strategy.Based on the light transmission concept behind the transparent wood,this paper describes the response mechanism,preparation process and related application of photo-responsive luminescent transparent wood.It is noted that the future research should be primarily directed to the investigation of the carbon dots photoluminescence mechanism,the multiplication of polymer synergy and the exploration of large-size preparation technology,in order to provide ideas for the industrialized development of photo-responsive luminescent transparent wood.
