WebDec 19, 2024 · Corrosionpedia Explains Hydrophobic. Hydrophobic refers to substances that cannot dissolve in water. Chemical groups that tend to make substances hydrophobic include -CH 2 - chains and rings (hydrocarbons). These substances lack the ability to hydrogen bond and their surface free energy is relatively low. WebDec 16, 2015 · Chlorotrimethylsilane is great for a completely hydrophobic surface as it will cap all of the S i − O H groups to S i − O − S i ( C H X 3) X 3 groups allowing no polar interaction of the surface with the water. dichlorodimethylsilane is not as good leaving you with − S i − O − ( S i ( C H X 3) X 2) − O − S i - and − S i − O − S i ( C H X 3) X 2 O …
