Exploring Surface Energy of Polymers by Contact Angle Estimation
Teaching Materials | 03 Dec 2020 | Contributor(s):: Fred Okoh, NNCI Nano
Students will qualitatively and quantitatively estimate contact angles of polymers and compare their surface energy. They will use a variety of polymer sheets onto which they will place drops of water. After observing the shape of the drop, they will take digital photographs of the drop, print...
