Abstract
|
PMSE 397 - The 232nd ACS National Meeting, San Francisco, CA, September 10-14, 2006 <br /><br />Polymer micro- and nanotubes find numerous applications in biotechnology, microfluidics and many other fields. We manufacture them by self-rolling of strained polymer bilayer films steadily released from solid substrates. Curling of the film is due to swelling of the bottom layer of the bilayer film in a selective solvent, opposed by the non-swollen top layer of the film. Poly(4-vinyl pyrrolidone)/polystyrene (P4VP/PS) tubes and poly(vinyl pyrrolidone)/polybutadiene (PVP/PB) tubes are rolled up in acidic water and pure water, correspondingly. Before rolling, the surface of the P4VP/PS layer was modified by adsorbtion of ZnO nanoparticles. The nanopartilces were also embedded in the PVP layer of the PVP/PB tubes. Functionalization of the tubes by the nanoparticles can be used for imparting the tubes photoluminescent and catalytic activity.
