Is epoxy resin a good candidate for use as a matrix of superhydrophobic coating?why?
Thanks
Dear Seyed Mohammad Reza Razavi
The choice of the polymer matrix for superhydrophobic coatings must be determined by the appointment of future coating. For what purpose you create the coating? In what media the coating will operate? For example, silicone varnishes for electrical purposes in particular polydimethylphenylsiloxane varnishes in creating a multimodal roughness exhibit a long-term superhydrophobicity under atmospheric aging, but they are not suitable to the conditions of static exposure to liquid media.

Hello,
nearly all the commercial avaiable epoxy resins have really polar chemical functional groups at their surface (Amino-, Hydroxy- )
The result is an contact angle to water of app. 50°
To get an superhydrophobic surface (contact angle to water > 100°) a chemical modification with fluorosilanes can halp.
best regards
Thanks dear Uwe
Did you suggest surface modification of epoxy resin with fluorosilane ??
Can you give me some ref about it, please?
Thanks again
