摘要: Abstract Conducting polymer image and diffraction grating pattern were recorded in dichromated poly(vinyl alcohol) (DCPVA) films by visible light exposure, a process resembling photolithography. Aniline, used as chemical developer, polymerized into the unexposed areas of DCPVA matrix, yielding composite material which allowed permanent optical information storage exhibited properties characteristic polyaniline. The photoreduction studied UV–VIS spectroscopy. characterization gave line width 12.15 μm efficiency 32%.
