In this paper, a novel morphology of polyaniline (PANI)/Ag composite nanospheres was obtained through UV rays irradiation method. The structure and morphology of the product were characterized by Fourier transform infrared (FT-IR) spectrum, X-ray diffraction (XRD) pattern, Scanning electron micrograph (SEM) and Transmission electron microscopy (TEM) images, energy-dispersive X-ray (EDAX) analysis, and electron diffraction (ED), respectively. The results showed that the diameters of the PANI nanospheres and the Ag nanofilaments were 10–60 nm and 2–5 nm, respectively. UV rays played an important role for forming PANI nanospheres underpinned by Ag nanofilaments. A potential formation mechanism of PANI nanospheres underpinned by Ag nanofilaments was investigated.
