There are various mechanical, chemical and thermal methods to improve the properties of wood which Their purpose is to block and reduce the reactivity of hydroxyl groups of cell wall polymers. The aim of this study is to modify the properties of Iranian beech wood ( Fagus orientalis L) via the passage of electricity.Three substances of water, salt solution in two levels and silver nanoparticles in two levels have been used to transfer electricity in wood. The experimental design was a factorial test on the basis of a completely randomized design to analyze the data obtained from the measurement of physical and mechanical properties. The results showed that the passage of electricity improved all the physical and mechanical properties of beech wood. Electric current passing via a 20% salt solution and 200ppm silver nanoparticles increased the Moduli of Rapture of beech wood respectively 25% and 29%. Electric current passing by both cause the Moduli of elasticity became more than fourfold And Anti-Swelling efficiency Based on the volume of beech wood obtained respectively 30% and 35%
