Influence of different solvents on the morphology of APTMS-modified silicon surfaces

- The amount of APTMS coating on the Si-oxide surface depends on the type of solvent.
- The morphology of the APTMS-modified surface is related to the solvent.
- In toluene and acetonitrile, heterogeneous and rough APTMS films were obtained.
- A smooth and thin modified surface was obtained using ethanol and acetone.
