POLY 20 |
| We have recently developed a novel method to deposit parylene nanowires that are free-standing, slanted, and spatially organized parallel columns. The surface-to-volume ratio of structured polymers is very high and the available surface area increases by more than two orders of magnitude in relation to the bulk material. We are studying nucleation, crystallinity and growth as well as pore size and geometries of structured parylene. For applications, the chemical and physical properties of the structured parylene surfaces are controlled by functionalization through physisorption of adsorbent materials that modify surface energies and properties, and chemisorption of a coupling reagent that attach biomolecules to the surfaces. Our deposition technique will also open a new wealth of applications to assemble many possible combinations of monomers that have desired functional groups for depositing novel polymers.
