Abstract

The biological resistance of rubberwood (Hevea brasiliensis Muell Arg.) treated with linseed oil and paraffin wax nanoemulsions containing zinc oxide (ZnO) and copper oxide (CuO) nanoparticles against a white-rot (Trametes hirsuta) and a brown-rot (Oligoporos placenta) fungus was investigated. Rubberwood specimens were treated with nano preservative formulations prepared by dispersing nano particles of ZnO and CuO (conc. 0.5–2.0% w/v) and exposed to brown-rot and white-rot fungus following IS-4873:2008 standard. The nanoemulsions containing ZnO and CuO nanoparticles exhibited good resistance to fungal decay, the efficacy of wood treated with CuO nanoparticles dispersed nanoemulsion was better than wood treated with ZnO nanoparticles dispersed nanoemulsion. Scanning electron microscopy and Fourier transform infrared (FTIR) spectroscopic analysis of decayed wood confirmed less degradation in nanoemulsion-treated wood compared to untreated specimens. This study depicts the nanoparticles dispersed wax and oil nanoemulsions as effective wood preservation strategy for enhancing the resistance of wood against wood decaying fungi.

用纳米氧化锌和纳米氧化铜分散亚麻籽油和石蜡纳米乳液处理的橡胶木的抗真菌性

研究了用含氧化锌（ZnO）和氧化铜（CuO）纳米颗粒的亚麻籽油和石蜡纳米乳液处理的橡胶木（Hevea brasiliensis Muell Arg.）对白腐菌（Trametes hirsuta）和褐腐菌（Oligoporos placenta）的生物抗性。按照 IS-4873:2008 标准，用分散氧化锌和氧化铜纳米颗粒（浓度为 0.5-2.0% w/v）制备的纳米防腐剂配方处理橡胶木试样，并将其暴露于褐腐真菌和白腐真菌中。含有 ZnO 和 CuO 纳米粒子的纳米乳液表现出良好的抗真菌腐朽性，使用 CuO 纳米粒子分散纳米乳液处理的木材的功效优于使用 ZnO 纳米粒子分散纳米乳液处理的木材。对腐朽木材的扫描电子显微镜和傅立叶变换红外光谱分析证实，与未经处理的样本相比，经纳米乳液处理的木材降解程度较低。这项研究表明，纳米颗粒分散蜡和油纳米乳液是一种有效的木材防腐策略，可增强木材对木材腐朽真菌的抵抗力。

期刊介绍： European Journal of Wood and Wood Products reports on original research and new developments in the field of wood and wood products and their biological, chemical, physical as well as mechanical and technological properties, processes and uses. Subjects range from roundwood to wood based products, composite materials and structural applications, with related jointing techniques. Moreover, it deals with wood as a chemical raw material, source of energy as well as with inter-disciplinary aspects of environmental assessment and international markets. European Journal of Wood and Wood Products aims at promoting international scientific communication and transfer of new technologies from research into practice.
