Coupling the epoxy with cadmium oxide particles are important for optical properties that may be affected by
various mixing proportions. The aim of this experimental study was to evaluate the effect of different mixing proportions
on these properties of reinforced epoxy with cadmium oxide particles. The ultrasonic techniques were used to mix and
prepared samples of composites. The surfaces topographic of the 50 μm thick reinforced epoxy films were studied using
atomic force microscopy (AFM) and microscopy technique (FTIR) Spectroscopy. AFM imaging and quantitative
characterization of the films showed that for all samples the root mean square of the surface roughness increases
monotonically with increasing the CdO concentrations (from 0% to 15%).The observed effects of CdO concentrations on
surface roughness can be explained by two things: the first reason is that the atoms of additives are combined with the
original material to form a new compound that is smoother, more homogeneity and smaller in particle size. The second
reason is due to high mixing due to ultrasonic mixing. It is clear also, AFM examination of the prepared samples of
reinforced epoxy resin shown that topographical contrast and the identification of small structural details critically
depend on hardness of epoxy resin, which in turn depended on the ratio of material (CdO) added. We show that the AFM
imaging of the films showed that the mean diameter (104.8nm) of films for all of the samples decreased from 135.50 nm
to 83.20 nm with the increase of CdO concentrations.
