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 TiO 2 as a reinforcing agent, the pore structure can be maintained perfectly after removal of the template. The porous materials reinforced with TiO 2 are more robust than those thermoset with DR only. The weight percent of TiO 2 in the robust macroporous materials has been determined to be ∼16%.
