Robust Macroporous Materials of Chiral Polyaniline Composites

3D macroporous materials comprising chiral polyaniline composites were prepared using polystyrene sphere as sacrificial template. By means of diazoresin (DR) as a thermosetting agent or TiO2 as a reinforcing agent, the pore structure can be maintained perfectly after removal of the template. The porous materials reinforced with TiO2 are more robust than those thermoset with DR only. The weight percent of TiO2 in the robust macroporous materials has been determined to be ∼16%.
