摘要
木材是地球上最丰富的可再生资源之一,在“双碳”战略背景下,可再生林木资源低碳、高效利用受到极为广泛的关注。通过在基础科学层面系统揭示林木资源的新型理化特性,进而创新林木资源的高效加工转化技术,是学界公认实现林木资源高效、低碳利用的必由之路。近年来,许多国内外研究组在研究过程中发现了林木资源包括发光、光热与光催化在内的多类新型光理化特性,以此为基础,发展了多类策略,实现了林木资源向光功能材料的高效转化。林木资源中其天然的结构和化学成分为其赋予了独特的光学性质,为光功能化提供了广阔的发展空间。尽管取得了显著的研究进展,但在林木资源光理化特性研究及其转化为光功能材料的过程中仍然存在许多的挑战。在该综述中,将尝试讨论以下4个问题:1)林木资源转化为光功能材料的优势是什么?2)林木资源内生光理化特性形成的分子机制与调控;3)林木资源向光功能材料的转化方法与潜在应用;4)林木资源光理化特性研究与转化为光功能材料过程中还存在什么问题?通过讨论上述问题,希望可以为林木资源的光理化特性研究提供一个新的视角,助力“双碳”战略下林木资源的高效利用。这一领域的研究不仅有助于推动可持续发展,同时在不断深化研究的过程中,林木资源有望成为多个领域中高效、可持续的光功能材料的重要来源。
Wood is one of the most abundant renewable resources,in the background of carbon neutralization,utilization of renewable forest resources received particularly attention.Seeking new fundamental theories and developing new technologies can greatly promote the utilizing efficiency of forest resources.In recent years,many research groups at home and abroad discovered that forest resources possessed inherent photoluminescence,photothermal conversion and photocatalytic properties.Based on these discoveries,these forest resources were efficiently converted to optical functional materials.The natural structure and chemical composition inherent in forest resources endow them with unique optical properties,which provide a broad development space for photo-functionalization.Despite significant research progress,there are still many challenges in the study of the photo-chemical properties of forest resources and their conversion into optical functional materials.In the review,we tried to discuss four crucial points in the research area including 1)the advantages for converting forest resources to optical functional materials;2)The correlation between“structure-optical performance”of forest resources;3)The conversion method and potential applications;4)The perspectives in the area.This review was expected to provide a new angle for the high-efficient and value-added utilization of the forest resources,and help the efficient utilization of forest resources under the carbon neutralization strategy.The research in this area will not only help to promote sustainable development,but also in the process of deepening the research,forest resources are expected to become an important source of efficient and sustainable optical functional materials in many fields.
