Abstract: We investigated the properties of inorganic–organic hybrid thin films prepared by sol–gel reaction. Sol solutions were synthesized by using two kinds of nanosized boehmite and methyltrimethoxysilane (MTMS) in variation with the amount of MTMS at different reaction times. Boehmite nano sol of spherical and fibrous shapes was used as inorganic material, and MTMS was used as organic material. The morphology of boehmite nano sol powder was observed by transmission electron microscopy. Coating sols were prepared from boehmite sol and MTMS by sol–gel reaction. Physical and chemical properties of thin films prepared from boehmite and MTMS sols were investigated. Surface hydrophobicity, roughness, thickness, thermal resistance and electrical resistivity of boehmite/MTMS thin films were investigated.
