Conductivity of the CSCBs and HSPBs by a standard 4-point probe technique at room temperature^(a).

CSCBs with core-PS^(b)	CSCBs with core PSMA	CSCBs with core PSVB	CSCBs with core-PSVC	CSCBs with core-PSSS	HSPBs^(c)
0.3 s/cm^2	0.20 s/cm^2	0.40 s/cm^2	0.67 s/cm^2	0.90 s/cm^2	0.25 s/cm^2

^(a)Poly(4-styrenesulfonic acid ) was used as a dopant.
^(b)The CSCBs with core-PS and shell PPy were prepared using SDS as anchoring agent.
^(c)TheHSPBs were measured in Figure 3.
