What type of water drop profile/contact angle works best for self-cleaning surfaces?

Would you consider your surface to be self-cleaning/super hydrophobic? Explain using a claim, evidence from your experiment and reasoning from any information you have been provided with today.

If you had to improve your modification method, how would you do this and why?

What there any limitations while you were prototyping and improving your mask designs?

I didn't have any wax which was needed for the prototype.

The best angle is <90
I didn't have any limitations

Limitations: I didn't have wax, so I had to listen to what others found with wax.
EDP: I learned that each step matters.

A high contact angle works the best. I would improve my modification by having polyester fabric and cotton fabric. My surface is not superhydrophobic. The water still soaks in a bit. Some limitations were the I had poly cotton instead of polyester and cotton, but it ended up working fine. A low roll off angle works best for self cleaning surfaces. One of my take aways from this engineering design process was that even if you have limited or different materials, you can still make things work. I did like the flow of the process.

My surface isn't super hydrophobic

What were the take aways from EDP you involved in these two weeks?
