Polymer chains, of microgels

Fig. 20 Selective AuNPs deposition on PEDOT nanorods in microgel structures (a) PEDOT nanorods are not fully oxidized and attract a small amount of counterions (green circles). The small amount of positively charged groups (red circles) are due to the incorporation of initiator residues into polymer chains of microgel. (b) After addition of H+, [AuCU]- PEDOT nanorods become oxidized in acidic pH and [AuCLt]" anions (yellow circles) are drawn into the microgel to compensate for a charge on the nanorod surface (white circles), (c) After addition of NaBH4 and a reduction process, AuNPs are predominantly formed on the PEDOT nanorod surface.
