Objective:
The overall objective of the project is to test the hypothesis that introduction of biocides into controlled-release nanoparticles reduces leaching of those biocides into the environment. By reducing biocide leaching, the negative environmental impact of treated wood is reduced while the useful lifetime of the wood product is increased. Self-assembled core-shell nanoparticles are being used in which the core is designed to serve as a protected reservoir of the biocide and to modulate its release rate while the shell serves to stabilize the nanoparticles in aqueous medium for wood treatment.Progress Summary:
The composition of the nanoparticles has been assessed, as have key features of the reaction conditions and composition related to objectives to improve performance of the nanoparticles. Small modifications of the composition have been shown to improve the biological efficacy of the nanoparticles with tebuconazole. Copper-containing nanoparticles have been prepared and studied. Analysis of the results was used to design new nanoparticles for field studies.Future Activities:
During the next year, we expect to perform additional leach studies and expand our work on copper preservatives, including wood decay studies. We are replicating some prior studies, specifically with additional leach studies, and will prepare wood stakes for field studies.Journal Articles on this Report : 1 Displayed | Download in RIS Format
