Abstract : The adhesion of a series of organosilanes, with varying lengths of alkyl chain, adsorbed on different metal-oxide substrates have been modelled using a computational molecular dynamics (MD) approach. The silanes modelled were: (a) the fully hydrolysed version of gamma- glycidoxypropyltrimethoxysilane (GPMS), (b) the fully hydrolysed version of gamma- glycidoxydecyltrimethoxysilane (GDMS), and (c) the fully hydrolysed version of gamma- glycidoxyeicosyltrimethoxysilane (GEMS). The substrates were corundum (alpha-Al2O3), an amorphous form of aluminium oxide (amorphous alumna, Al2O3) and haematite (Fe2O3).
