Using the NBBs approach and acid-catalyzed reactions of tetraethoxysilane and triethoxy(octyl)silane, different procedures were used for preparation of six sols. Besides three different ways of mixing of initial precursors, two temperatures with different reaction time were used. The films were prepared by dip-coating technique and treated at temperature of 170°C. The sols were characterized by method of dynamic light scattering. The surface of films was characterized by atomic force microscopy and sessile drop technique. The influence of sol preparation procedure and reaction conditions on particles size in sols as well as the properties of films surface, such as hydrophobicity, morphology and rms-roughness, was observed. The procedure of sol preparation markedly influences the surface morphology of prepared nanocomposite inorganic-organic films. The changes in the studied properties were mainly observed for films, which were deposited from sols prepared at boiling temperature of isopropyl alcohol.
