Preparation of Polyaniline/Polyurethane (PANI/PU) Photonic Thin Films by Evaporative Self-Assembly: Growth and Properties

摘要

Solvent dissociation self-assembly method was used to prepare ordered porous films with special morphology on the surface. Herein, we report the preparation of polyaniline/polyurethane (PANI/PU) concave lens arrays using porous membrane as a template. The morphology of the PANI/PU nanocomposite concave lens array obtained by interfacial polymerization was characterized by scanning electron microscopy (SEM) and the influence of various concentrations of tetrahydrofuran solution on the properties of the nanocomposite photonics thin film were studied. Further, the electrical and optical properties of the PANI/PU concave lens array were also studied. The detailed studies revealed that the PANI/PU concave lens array has both conductivity, electrostriction and light diffraction properties.
