摘要： In this manuscript, a facile strategy was proposed to synthesize hollow spherical polyaniline by using the functionalized polystyrene sphere as the template, the resulting hollow spherical polyanilines were primarily uniform and few of them were stuck together. The obtained polyaniline was semicrystalline emeraldine with the S-BET of 14.1 m(2) g(-1) and an average diameter of 300 nm as well as a shell thickness of 100 nm. This strategy probably provided a potential way to synthesis of the hollow spherical polyaniline. Furthermore, the synthesized hollow spherical polyaniline displayed high adsorption capacity of CR (46.91 mg g(-1)) and RhB (61.75 mg g(-1)). These values were higher than many other polyaniline-based adsorbents. The results suggested that the fabricated hollow spherical polyaniline had potential to be employed as adsorbent for CR and RhB removal.
