Nano-scale analysis of copper in wood cell walls treated with amine-copper solution

本研究的目的是研究铜在胺铜防腐剂处理的管胞细胞壁中的纳米分布。采用聚焦离子束（FIB）微加工技术对胺铜处理木材进行超薄切片电镜观察。通过最先进的HR（高分辨率）-TEM（透射电子显微镜）和HAADF-STEM（高角度环形暗场扫描透射电子显微镜）- EDX（能量色散X射线检测器）测定切片。结果表明，FIB切片结合HR-TEM和HAADF-STEM-EDX是观察铜在木材细胞壁中纳米分布的有力工具。

The purpose of this study is to examine the nanodistribution of copper in cell walls of tracheid treated with amine copper preservative. FIB (Focused Ion Beam) micro processing was used to make ultra-thin sections amine copper treated woods for electron microscopy. The sections were determined by state-of-the-art HR (High Resolution)-TEM (Transmission Electron Microscope) and HAADF-STEM (High-Angle Annular Dark-Field - Scanning Transmission Electron Microscope) - EDX (Energy Dispersive X-ray detector). The results show that FIB sectioning in combination with HR-TEM and HAADF-STEM-EDX is a powerful tool for observing the nanodistribution of copper in wood cell walls.
