Dear All!
    Myself, R.Kannan, Research Scholar in Aerospace Engineering Department of
IISc Bangalore. I am working in the area of Liquid drop impact over
Superhydrophobic surfaces. I am thinking of getting surfaces with a contact
angle ranging from 130 to 170 using fluoropolymer coated nanostructured
surfaces. I decided to go with Al or Al2O3. will it be useful to get this much
amount of contact angle. I decided to prepare the Nanostructured surfaces using
Electron Beam Method. Please help me by providing the details of substrate
temperature and other related settings for E Beam to coat Al or Al2O3. How much
roughness can i get that method ? Please help me in this regard.
          Thanking you,
                         Yours Truly,
                           R.Kannan.
