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.
