Abstract The effectiveness of protective coatings based on 3-(2,2,3,3,4,4,5,5-octafluoropentyloxy)propyltriethoxysilane in the protection of wood surface from the effects of water was tested. No earlier attempts at using the mentioned fluorocarbosilane for the protection of wood have been reported in the literature. The coatings were deposited by the sol–gel method. As a result of the generation of chemical bonds between the wood surface and silane, a coating was produced that permanently increased the wood hydrophobicity. Fluorinated chains attached to the silicon atoms make an effective barrier preventing the access of water and limiting the effects of water on the wood surface.

The formation and characterization of thin ceramic coatings is currently an active area in materials science. Specifically, there has been increased interest in these materials as dielectric and optical layers for advanced microelectronic circuitry [1]. This is in addition to their continued use and evaluation as protective coatings in a variety of applications [2]. One method of forming these coatings is via the sol-gel technique. However, only a few papers have been published in this area [3–7]. Dense silicon dioxide, aluminium oxide and various glass compositions have been deposited in thin film form on various substrates. Further, silicon dioxide films, formed by the sol-gel method, have been nitrided in ammonia at high temperatures and partially converted to an oxynitride [8–11]. These films were shown to be highly non-homogeneous, with a predominance of nitrogen at the surface. Despite the desirability of dense uniform well bonded coatings of the nitrided ceramics, i.e. Si3N4 and the oxynitrides, no method yet exists for the formation of nitrides by the sol-gel method.

The article shows the possibility of applying a silicon dioxide coating on the carbon fiber by the sol-gel method. The evaluation of the protective properties of the obtained coatings at a temperature of 600 ° C is given; the changing of the a coated fiber surface morphology during the destruction process is shown for the first time. The destruction of the carbon fiber surface without coating begins at a soaking time of 120 min, which is accompanied by a significant decrease in the diameter of the fiber. The destruction of the coated carbon fiber surface begins at a soaking time of 360 minutes, the fiber diameter changes insignificantly. The paper shows that the sol-gel coatings slow down the oxidation of the carbon fiber more than 2 times.
