An ecological method to improve the durability of bamboo has been proposed by electrochemical silver modification of hemicellulose and lignin. The influences of silver electrochemistry on the different sections of bamboo cross (BC), bamboo radial (BR), bamboo skin (BS) and bamboo pith (BP) were studied. The surface morphology and chemical properties of different bamboo sections were studied by environmental scanning electron microscope (ESEM), Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS). The crystallite size of the silver particles was analyzed by X-ray diffraction (XRD). The fixation performance of silver particles was evaluated by leaching test. The microstructure and chemical composition of the bamboo were continuously observed and analyzed by ESEM and FTIR. The results showed that silver nanoparticles were uniformly distributed on the bamboo surface. BP had the most silver content due to more lignin and hemicellulose. A greater depth of penetration of the silver particles was observed for BC which has a vertical arrangement of its tissue. The mass loss rate of the different treated bamboo sections was significantly reduced by the decomposition of the fungi, especially for BS and BP (< 1 %). This study indicates that electrochemical silver modification of bamboo could be an effective alternative to the currently used preservation methods.

通过对半纤维素和木质素进行电化学银改性，提出了一种提高竹子耐久性的生态方法。研究了银电化学对竹十字（BC）、竹辐（BR）、竹皮（BS）和竹髓（BP）不同截面的影响。采用环境扫描电子显微镜（ESEM）、傅里叶变换红外光谱（FTIR）和X射线光电子能谱（XPS）对不同竹节的表面形貌和化学性质进行了研究。通过X射线衍射(XRD)分析银颗粒的微晶尺寸。通过浸出试验评价银颗粒的固定性能。通过ESEM和FTIR连续观察和分析竹子的微观结构和化学成分。结果表明，银纳米粒子均匀分布在竹材表面。由于木质素和半纤维素较多，BP 的银含量最高。对于组织垂直排列的 BC，观察到银颗粒的穿透深度更大。由于真菌的分解，不同处理竹节的质量损失率显着降低，特别是对于 BS 和 BP (< 1 %)。这项研究表明，对竹子进行电化学银改性可能是目前使用的保存方法的有效替代方法。由于真菌的分解，不同处理竹节的质量损失率显着降低，特别是对于 BS 和 BP (< 1 %)。这项研究表明，对竹子进行电化学银改性可能是目前使用的保存方法的有效替代方法。由于真菌的分解，不同处理竹节的质量损失率显着降低，特别是对于 BS 和 BP (< 1 %)。这项研究表明，对竹子进行电化学银改性可能是目前使用的保存方法的有效替代方法。
