I am trying to coat PDMS and Polyimide with (3-mercaptopropyl)trimethoxysilane and (3-glycidyloxypropyl)trimethoxysilane respectively. I was wondering whether these surfaces should exhibit a hydrophobic behavior
The mercaptofunctional silane is relatively hydrophobic. The glycidoxy functional silane is relatively hydrophilic. See:https://www.gelest.com/themencode-pdf-viewer/?file=https://www.gelest.com/wp-content/uploads/Hydrophobicity-Hydrophilicity_and_Silane_Surface_Modification.pdf
