In this study, a simple and effective method for preparing bamboo with high fungal resistance was first proposed. Flattened moso bamboo ( Phyllostachys pubescens ), which is a perishable species, was connected to a silver plate and exposed to a high-voltage electrostatic field (HEVF). The method was based on HEVF excitation of a silver plate to produce silver ions and facilitate in situ impregnation of bamboo. Silver ions were present in the forms of Ag(0), Ag(I) and Ag(III) and reacted with bamboo functional groups under HVEF treatment. X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy analysis showed that compared to those of untreated bamboo, the O/C ratio and OH content of treated bamboo were lower, the number of CHO groups decreased, the number of CO groups increased, and silver interacted with the hemicellulose and lignin of bamboo. The concentration of silver ions increased with increasing treatment time and voltage. The silver ions were nanocrystalline, and the average particle size was 50 nm. The mass loss and moisture content of the treated bamboo decreased significantly after exposure to decay fungi. Therefore, in situ impregnation of silver with HVEF was a simple and effective method to improve the durability of bamboo materials.

银的竹电化学处理及其对腐烂真菌的影响

在这项研究中，首先提出了一种简单有效的方法来制备具有高抗真菌性的竹子。将易腐烂的扁平毛竹（Phyllostachys pubescens）连接到银板上，并暴露于高压静电场（HEVF）中。该方法基于银板的HEVF激发，以产生银离子并促进竹子的原位浸渍。银离子以Ag（0），Ag（I）和Ag（III）的形式存在，并在HVEF处理下与竹官能团反应。X射线光电子能谱和傅里叶变换红外光谱分析表明，与未处理竹相比，处理竹的O / C比和OH含量更低，CHO组数量减少，CO组数量增加，银与竹的半纤维素和木质素相互作用。银离子的浓度随着处理时间和电压的增加而增加。银离子为纳米晶体，平均粒径为50nm。暴露于腐烂真菌后，处理过的竹子的质量损失和水分含量显着降低。因此，用HVEF原位浸渍银是提高竹材料耐久性的一种简单有效的方法。
