The properties of composites are controlled by the interfacial region, a three-dimensional area (interphase) formed as a result of reactions between the reinforcement (fibers) and the matrix. A good interface bonding to ensure the load transfer from the matrix to the fiber is a primary requirement for the effective use of reinforcement properties 1,2. There have been continuous efforts to improve the interfacial adhesion (a primary factor for stress transfer from the matrix to the fiber) in glass reinforced materials by using surface sizes such as silane coupling agents 3,4. Silane coupling agents are commonly applied on the glass fibers surfaces from the liquid solutions in order to produce sizing. It is also known that the density of finally formed siloxane bonds is low and the bonds are hydrolytically unstable 4. This problem is at these days often resolved with plasma surface modification and treatment. Polymer films prepared during plasma polymerization are highly crosslinked, insoluble and generally have excellent chemical, mechanical and thermal properties 5. The aim of this study was to prepare thin films with siloxane structure by two different types of technologies (plasma polymerization technique and wet-chemical process) and compared them with respect to chemical composition (XPS) and surface morphology (SEM, AFM).
