Abstract :
Summary form only given. Plasma assisted organosilicon film deposition from HMDSO compound is already well established technique. Poplar veneer were tested for creating the water repellent surface from HMDSO comound by surface dielectric barrier discharge (SDBD) plasma at atmospheric pressure. Depending on the flow rate of nitrogen and the HMDSO flow through nitrogen was studied in order to optimize the coating properties. Surface properties of thin film on poplar veneer samples deposited by plasma were studied using the sessile droplet technique to identify surface free energy of treated and untreated samples. The adhesion was measured between water based glue and hydrophobic layer to determine property of hydrophobic layer. The measurements were performed according to Slovak Technical Norm EN 24624. The chemical composition of the deposit layer were analyzed by ATR-FTIR.
