Webb26 sep. 2024 · Octadecyltrichlorosilane (OTS) is a commonly used reagent for hydrophobic surface modification (Zhang et al. 2024; He et al. 2013 ). The trichlorosilane group in OTS reacts with an –OH attached surface to form chemical bonds; the alkyl-chains in OTS then bond to the surface to make it hydrophobic.

A hydrophile is a molecule or other molecular entity that is attracted to water molecules and tends to be dissolved by water. In contrast, hydrophobes are not attracted to water and may seem to be repelled by it. Hygroscopics are attracted to water, but are not dissolved by water.
