Chang-Sik Ha is professor in the Department of Polymer Science and Engineering, Pusan National University (PNU), Korea, since 1982. He obtained his BS and MS in chemical engineering from the PNU and the Korea Advanced Institute of Science and Technology (KAIST), Daejeon, Korea, respectively, and his PhD in polymer physics from KAIST in 1987. He served as vice president of the PNU; president of the Society of Adhesion and Interfaces, Korea; and director of the Pioneer Research Center for Nanogrid Materials, National Research Foundation of Korea. He was elected to both the Korean Academy of Science and Technology (KAST) and the National Engineering Academy of Korea (NEAK) in 2004. He has also served as an editorial board member of several international journals. Prof. Ha has received many awards, including the Samsung Polymer Science Award from the Polymer Society of Korea and the Scientist of the Month Award from the Ministry of Science and Technology, Korea, as well as an international award from the Society of Polymer Science, Japan. He has 72 patents to his name and has written 22 books and more than 700 articles in refereed journals. His research interests include materials for drug delivery systems, mesoporous materials and nanostructured materials, functional polymers, organic-inorganic nanohybrid materials, and bioinspired materials for superhydrophobic and superoleophobic coatings.Saravanan Nagappan received his PhD in polymer science and engineer-ing from the PNU under the guidance of Prof. Chang-Sik Ha. He is now a postdoc fellow at the PNU and has been working on organic-inorganic nanohybrid materials and their applications, including hydrophobic and superhydrophobic coatings.
