AFM maps with indicated locations of SNOM-IR spectra of (a) PPy reference (b) O-DND/PPy (c) poly-DND/PPy. The lateral size of the particles’ and PPy agglomerates could be deduced from the scale bars on AFM images. Characteristic PPy peaks at 1671 (N–H vibration) and 1408 (C–N vibration) cm−1 are indicated at SNOM-IR spectra.
