Abstract

Background and objectives: Nowadays, some attempts are done to use nanoparticles as a preservative for wood. It seems that the using nanoparticles with polymeric materials could improve undesirable properties of wood such as dimensional stability and leaching of nano particles. In this study, Physical properties and leach resistance of eastern cottonWood-polymers that treated with copper oxide nanoparticles were studied. Materials and methods: Wood samples with 20×20×20 mm dimensions were papered and then impregnated with polymers and nano copper oxide by full cell method. In this research variable factors were concentration of Polystyrene (40 and 80 percent) and nano copper oxide (0, 0. 4 and 0. 8 percent). After preparing Samples, they were immersed in 100 ml of DI water and their water absorption, volumetric swelling and leach resistance were calculated. Results: Obtained results showed that treated samples had less volume of water absorption and volumetric swelling. For example, the average water absorption and swelling volume after 168 hours immersion in water were 33. 5 and 4. 5 percent respectively for samples that treated by Polystyrene at concentration of 80 percent and nano copper oxide at concentration 8. 0 percent, while these values were 127 and 11. 8 percent respectively for control samples. The rate of leaching copper oxide in the presence of Polystyrene was less than 1% for all the treatments. Conclusion: Treating Wood with nano copper oxide in presence of Polystyrene reduced water absorption and improved dimensional stability. Moreover, these samples had a little rate of copper leaching.
