Abstract: CdS/PMMA composite film with different amount of CdS was prepared by using the solution cast technique. The composite films were characterized by Scanning electron microscopy (SEM) to detennine the surface morphology of composite film, Fourier transfonn infrared spectroscopy (FTIR) to monitor the fonnation bonding between CdS and PMMA, Electrochemical impedance spectroscopy (EIS) to determine the conductivity of composite film. The SEM revealed that CdS particle were homogeneously dispersed in PMMA polymer matrix. With the amount of CdS increasing, the size of CdS particles was increased and CdS particles became agglomerated. FTIR spectra of CdS/PMMA composite film indicated the present of sulfur in PMMA polymer at peak 841cm- 1 and the peaks at the range 1790 - 1675 crn- 1 and 1220 - I 095 cm- have increased the intensity of absorption with increase the wt% of CdS. The EIS result showed that increasing amount of CdS has resulted in increasing the conductivity and increase in conductivity can also be associated to the increase in the arnorphosity as shown by SEM studies.
