Abstract
Novel 3D hollow spheres (diameter ≈525 nm, thickness ≈70 nm) self‐assembled from 1D PANI nanofibers (diameter ≈17 nm) with conductivity of 1.11 × 10^−1^ S · cm^−1^ are synthesized template‐free by using FeCl~3~ and salicylic acid as the oxidant and dopant, respectively. In this method, the reaction of aniline with FeCl~3~ and SA to form conductive PANI and the reaction of SA with FeCl~3~ to produce a color complex, assigned as Fe(OR)^2+^, wherein OR represents the ionized phenol, coexist. The coexistence of two reactions results in a cooperative effect of the micelle, where aniline/SA acts as as a soft template of the nanofibers and the color complex as a soft‐template of the spheres, to allow the self‐assembly of complex micro/nanostructures via hydrogen bonding as the driving force.
