Effects were studied of zycosil nanoparticles, with size range from 30 to 90 nm, on liquid and gas permeability of medium density fiberboard. 100 g of nanozycosil was added to each kg of dry fibers. Density was kept constant at 0.67 g/cm3. The obtained results indicated that addition of zycosil to the mat resulted in a significant increase in gas permeability due to the lower fiber-content in the nanozycosil-treated specimens and the consequent micro-cavities that were formed in the boards. However, the water-repellant property of zycosil nanoparticles compensated for the micro-cavities to some extent, consequently the liquid permeability decreased significantly.
