Surface hydrophobicity Treatment:

A hydrophobic surface is a water repelling, low surface energy surface that resists wetting. Moisture contact angle measurements will classify a surface as hydrophobic when the contact angle of the water droplet exceeds 90 degrees. Superhydrophobic surface is classified if the contact angle mark exceeds 150 degree. We have various surface treatment techniques to turn surface more hydrophobic. We also have various techniques to turn surface more hydrophilic. Hydrophilic surfaces are high surface energy substrates that attract water and allow wetting of the surface. They typically have a droplet contact angle measurement of < 90 degrees.
