I have some glass beads and I need to create different levels of hydrophobicity on their surfaces (various contact angles). I know that this is possible by 'silanization'. However, I need to know about the following questions:
- Whether there is any other reasonable method to do that.
- In silanization, how can I change the level of hydrophobicity that my glass beads achieve? (e.g. by changing coating time, using different solutions or concentrations, etc.)
PS. I have the following solutions for silan. Please let me know if anybody has any comments on them or knows a more suitable solution for this purpose. - CHLOROTRIMETHYLSILANE - DICHLORODIMETHYLSILANE - TETRAETHYL ORTHOSILICATE - OCTADECYLTRICHLOROSILANE
