Abstract

Porous polymer colorimetric vapor- sensing elements have been produced using a holographic interferometry technique. Acetone vapor is detected by the change in the peak reflective wavelength of the resulting photonic bandgap structures (see Figure). The transmission electron microscopy image (Figure, inset) shows the voids generated in the film by adding a non-reactive solvent to the prepolymer syrup.
