γ-Irradiation was successfully used to prepare nanocrystalline composites of PbS/polyacrylonitrile with 23 wt.% lead sulfide at room temperature, in which the inorganic component displays homogeneous dispersion in the polymer matrix. X-Ray powder diffraction and infrared spectra were used to characterize the product. Its morphology was determined by transmission electron microscopy.
