Preparation of (PVA-PEG-PVP-MgO, CoO) Nanocomposites and Study their Optical Properties
Ibrahim R.Agool, Ahmed Hashim
Nanocomposites have many applications such: optical integrated circuits, sensors, coatings, medical devices.. etc. So, this paper aims to preparation of new type (PVA-PEG-PVP- MgO, CoO) nanocomposites to production new nanocomposites use in many. applications. The nanocomposites were prepared by using casting technique. The polymers was mixed with different weight percentages are (PVA0.90-PEG0.05-PVP0.05). The nanomaterials (MgO and CoO) were added to polymers composites with concentrations are (0, 2, 4 and 6) wt. %. The results show that the absorbance (A) of nanocomposites is increased with increase of concentrations of magnesium oxide and cobalt oxide nanoparticles. The optical constants (absorption coefficient (), extinction coefficient (k), refractive index (n), real and imaginary dielectric constants (1 and 2) ) of nanocomposites are increasing with the increase of the weight percentages of magnesium oxide and cobalt oxide nanoparticles. The energy gap (Eg) of (PVA-PEG-PVP) decreases with the increase of the weight percentages of magnesium oxide and cobalt oxide nanoparticles.
