The silanization reaction on polycrystalline titanium surfaces has been studied from the point of view of engineering a densely packed chemisorbed layer at the interface. For this purpose methyl‐ n ‐octyldichlorosilane (MODCS) and 2‐methyl‐1‐trichlorosilylundecane (2MTCSU) were used and compared with n ‐octyltrichlorosilane (OTCS). X‐ray photoelectron spectroscopy and contact angle measurements reveal that 2MTCSU forms well covering but not so densely packed monolayers as does OTCS. In contrast to 2MTCSU, MODCS does not provide a proper modification of the surface because of the small amount of molecules chemisorbed on the surface. Copyright © 2000 John Wiley & Sons, Ltd.
