Figure 1. Fabrication and characterization of SWNT-PLGA-Composites.

Figure 1

(a) SEM image of the electrospun PLGA substrate prior to incorporation with SWNT (b) Optical image of the impregnated area (c) SEM image of the substrate after impregnation (Bundles of SWNT can be identified in Figure S2 in the Supporting Information). (d) Vacuum impregnation method used to forcibily drive an aqueous SWNT dispersion into the hydrophobic substrate (e). Raman spectroscopy results confirm the presence of SWNT in substrate after wetting.
