دراسة بعض الخواص البصرية و الكهربائية للبولي فينيل الكحول المشوب بثلاثي كلوريد الحديد (FeCl3)‎

Abstract EN

In this study, polyvinyl alcohol (PVA) films were prepared with different percentages of (FeCl3) by casting method at room temperature andwithstudying the change in some optical and electrical properties of polyvinyl alcohol before and afterFeCl3addition by using the spectrophotometer (UV-1800) to record absorption and permeability spectra within the range of wavelengths (190-1100)nm and calculate the coefficient of absorption for direct and indirect transmission.

The use of Fourier transform Infrared (FTIR) spectrometer type (SHIMADZU) was studied within the range of wavelengths (400-4000) cm-1 and recording the change in polymer molecular bonding by identifying the tops of the spectral beams of the active functional group of polymer before and after adding FeCl3.

The electrical conductivity of polymer is also studied before and after the addition.

The results showed that increasingFeCl3concentration in PVA Solution resulted in increasing all the pervious properties except the permeability, which decreased with increasingFeCl3 concentration.
