功能化碳纳米点在木材表面耐光老化的应用研究
Study on Wood-Derived Fluorescent Carbon Dots and Their Application in Wood Surface Anti-Discoloration Performance
摘要
Abstract
To improve the photostability of decorative wood,the ultra violet(UV)light-resistant and anti-discoloration treatment is an effective strategy.The primary carbon dots(CDs)were prepared through a hydrothermal reaction using Chinese fir wood powder and water as the solvent.Novel functionalized carbon dots(TAM-CDs)with tetramethylpiperidin-amine(TAM)were synthesized through a hydrothermal-assisted coupling reaction.The ayus(Triplochiton scleroxylon)veneer treated with TAM-CDs was characterized by fluorescence spectroscopy and chrominance parameters methods.The optical properties of TAM-CDs and their application on the veneer surface were investigated.The surface CIE coordinates were applied to analyze the color change of veneer during yellowing process.The results show that the size of the synthesized TAM-CDs is relatively uniform with an average size of about 5 nm.The aqueous solution of TAM-CDs,demonstrating good UV absorption performance,exhibited a maximum fluorescence emission wavelength at 448 nm.The track of CIE coordinate showed that TAM-CDs effectively inhibited the yellowing defect of wood surface,and significantly delaying the long-term anti-discoloration behavior of wood materials exposed to sunlight and UV light.关键词
