Nanotechnology and Wood Preservation - New Products

Due to CCA treated wood being banned in the USA for residential uses by the end of 2003, the timber industry is looking to nanotechnology for cost-effective, long-lasting, anti-microbial products with similar outdoor performance to current pressure-treated wood.

The small size of nanomaterials means penetration into the wood fibre lattice is readily achieved but longevity of performance is often missing. Incorporating nanomaterials like zinc oxide, doped zinc oxides or copper oxide into wood preserver has been shown to improve performance longevity.
