Abstract


  • Polypyrrole (PPy) with photonic crystal structures were synthesized from Morpho butterfly wings using

    a two-step templating process. In the first step photonic crystal SiO2 butterfly wings were synthesized

    from Morpho butterfly wings and in the second step the SiO2 butterfly wings were used as templates for

    the replication of PPy butterfly wings using an in situ polymerization method. The SiO2 templates were

    then removed from the PPy butterfly wings using a HF solution. The hierarchical structures down to the

    nanometer level, especially the photonic crystal structures, were retained in the final PPy replicas, as

    evidenced directly by field-emission scanning electron microscope (FE-SEM) and transmission electron

    microscopy (TEM). The optical properties of the resultant PPy replicas were investigated using reflectance

    spectroscopy and the PPy replicas exhibit brilliant color due to Bragg diffraction through its ordered

    periodic structures. The preliminary biosensing application was investigated and it was found that the

    PPy replicas showed a much higher biological activity compared with PPy powders through their response

    to dopamine (DA), probably due to the hierarchical structures as well as controlled porosity inherited

    from Morpho butterfly wings. It is expected that our strategy will open up new avenues for the synthesis

    of functional polymers with photonic crystal structures, which may form applications as biosensors.
