Effect of Nano-Zinc Oxide on the Physical and Mechanical properties of Paulownia Wood (Paulownia fortunei)

Present research was conducted investigate to physical (water absorption and volumetric swelling) and mechanical properties (MOE, MOR, Compression strength parallel to the grain and hardness) of Paulownia fortunei impregnated with Nano-zinc Oxide with size range from 10 to 80 nm. Specimens were impr...

description Present research was conducted investigate to physical (water absorption and volumetric swelling) and mechanical properties (MOE, MOR, Compression strength parallel to the grain and hardness) of Paulownia fortunei impregnated with Nano-zinc Oxide with size range from 10 to 80 nm. Specimens were impregnated with a 5000 ppm aqueous suspension of nano-zinc oxide, at 2.5 bars in a pressure vessel for 20 minutes. Results showed that modulus of rupture (MOR), modulus of elasticity (MOE) and compression strength parallel to the grain were significantly increased in impregnated specimens. The only mechanical property decreased by nanoparticle-impregnation was hardness. Highest water absorbtion and volumetric swelling took place during first 8 hours of soaking period. Results of the analysis of variance showed that the impregnation of wood with nano-zinc oxide was positive and significantly affected water absorption and volumetric swelling of Paulownia fortunei.
