Description: Advances in wood protection based on nanotechnology are being developed to improve resistance of wood products to biodeterioration, reduce environmental impacts from chemical leaching and resist UV degradation of in-service wood. A number of different approaches have been explored. First, the nanometals zinc oxide and copper oxide were evaluated as preservative treatments for wood. Both nanoZnO and nanoCuO were leach resistant. NanoZnO also inhibited decay fungi, acted as a termite toxicant, and provided photostability of wood against UV degradation. Second, self-assembling nanopolymer matrices were permeated with an organic biocide. The porous surface of the nanopolymer encapsulated and retained the biocide until a change in the physical environment, such as elevated temperature, triggered its release. Third, a nanocarrier system utilized inert nanotubules loaded with organic biocides for targeted delivery and slow, controlled release of biocide. Fourth, nanoentrapment assessed the ability of cellulose nanocrystals (CNC) to chemically bind and entrap soluble biocides within the wood structure without modifying the wood matrix. Merits of each approach will be discussed.
