Abstract Using liquid paraffin (LP) as a non-polar solvent, aliphatic linear non-branched alcohols (LNA)s, which consist of relatively non-polar alkyl moieties, were covalently attached to the surfaces of oxidized silicon and soda-lime glass (SLG). Atomic force microscope (AFM), home-made grazing angle mirror-backed reflection Fourier transform infrared spectroscopy (GMBR-FTIR) and static water contact angle measurements (WCA) were used to examine the presence as well as the quality of the LNAs monolayers attached to the surface of SLG and oxidized Si(100) surfaces “SiOxSi-(100)”. By using our home-made GMBR-FTIR sampling method the IR signal (in C-H absorption regions) of self-assembled monolayers at both surfaces, SLG wafer and SiOx-Si(100) were directly analyzed. Analysing the AFM image of not fully covered 1-dodecanol (1DD) modified Si(100) surface “1DD-Si(100)”, in which the surface is modified at very low temperature, revealed the thickness of these ultra-thin films (≈1.2 nm) and it seems to be matched with thickness of 1DD-Si(100) monolayers.
