Decay resistance of Nano Zinc Oxide treated Cotton wood

Prepa ration of nan ometer-size metal particles essentia lly increases the effective surface area of the metal in an ev enly dispersed layer. If the particl e size is sm aller than the diameter of the wood window pit or the opening of th e bordered pit, complete penetration and uniform distribution woul d be expect ed [۱]. Seco ndly, nano metal prepa rations have a low viscosity. The addition of a surfactant can further increase dispersion stability by enabling liquid dispersion of higher concentrations of nanometals. Combined these prope rties prese nt the potential for greater penetratio n and protection from more unifor m particulate distribution over a wood surface [ ۲]. In this research was used of na no zinc oxide suspension with along to polymeric surfact ant of polye thylene glycol ۴۰۰ and a crylic surfactant and D ecay resista nce of treate d wood specimens with this material was investigated.
