摘要：

Polypyrrole (PPy) and its acid/base composites (PPy center dot H2SO4, PPy center dot HCl and PPy center dot NH3 center dot H2O) were successfully synthesized and were characterized respectively by using fourier transform infrared, ultraviolet/visible absorption, X-ray diffraction, transmission electron microscopy and Raman spectroscopic techniques. The nonlinear optical properties of PPy and its acid/base composites were investigated using nanosecond Z-scan measurements at 532 nm. At the identical linear transmittance, the saturable absorption of pure PPy was changed to reverse saturable absorption by doping with acid (HCl and H2SO4) and base (NH3 center dot H2O). The possible mechanisms for the different nonlinear properties were also discussed. (C) 2015 Elsevier B.V. All rights reserved.
