Question

Name two instrument used for measuring hydrophobic and hydrophilic naure of the sample

Answer 1

Hey mate here's your answer

Try to make a thin film of alumina nanoparticles and measure contact angle.Contact angle measurements are the easiest way to see the wettability of your samples. XPS analysis can also give an idea by looking at surface chemical composition. But this is an expensive and not-to-the-point way to see the hydrophobicity or hydrophilicity. You may use double stick tape to form a thin layer of alumina nano particles .
