Molecular Dynamics Study of Conformational Transitions of Poly(N-isopropylacrylamide) Hydrogels on Graphite Oxide Thin FilmPoly(n-isopropylacrylamide) (PNIPAM) as one of the thermo-sensitive polymers, has a coil-to-globule transition as the temperature is raised through the lower critical solution temperature (LCST). The transition has important applications in drug delivery, medical diagnostics, tissue engineering, electrophoresis and separation. Due to the special physical and chemical properties of graphene oxide (GO), the GO film has attracted attention as in next-generation electronic devices such as nonvolatile and thin film transistor. In this project, we are going to make a PNIPAM -GO thin film and study the possible new properties through molecular dynamics simulation. A Linux-based molecular dynamics software GROMACS and a windows-based software COMSOL will be utilized in modeling and simulation of the new material at molecular level and device level.
Ze Zhang, originally from China, is a Junior at Central Michigan University studying Electrical Engineering. Given the opportunity to work with a high school teacher, Ze readily accepted the challenge to teach programming and collaborate on the molecular dynamics project. Ze likes the Mt. Pleasant community and the opportunities it provides. Upon completion of his undergraduate degree, he will continue with graduate school still yet to be determined. Someday he hopes to work with micro computer chips, but he has other interests as well. On the lighter side, Ze is interested in jazz music and playing pool.
