Fabrication of Polyvinylpyrrolidone Micro-/Nanostructures Utilizing Microcontact Printing
Sanders, Wesley C.
Journal of Chemical Education, v92 n11 p1908-1912 Nov 2015
This paper describes a laboratory exercise that provides students enrolled in introductory nanotechnology courses with an opportunity to synthesize polymer structures with micro- and nanoscale dimensions. Polyvinylpyrrolidone (PVP) films deposited on corrugated PDMS stamps using student-built spin coaters were transferred to clean, dry substrates via microcontact printing. The microscale dimensions of the resulting patterns were characterized in class using optical microscopy. Characterization with atomic force microscopy (AFM) was used for visualization of nanoscale vertical dimensions of the structures. This laboratory investigation highlights the following concepts often associated with polymer nanostructure fabrication: polymer synthesis, surface chemistry, soft lithography, and contact angle. It is noteworthy to mention that this laboratory exercise demonstrates the feasibility of utilizing nontoxic, cost-effective, bench-top materials to teach and investigate fundamentals associated with fabrication of polymer nanomaterials.
