SYNTHESIS AND CHARACTERIZATION OF POLY (3HT - Co - Th) - PMMA POLYMER BLEND FILMS

Poly(3 - Hexylthiophene - Co - Thiophene) copolymer was preparedby applying the additionpolymerization method.Then, the copolymer was added to the poly(methylmethacrylate) (PMMA) polymer to produce the poly(3HT- Co - Th) - PMMA polymer blend. In order to characterize the optical properties of the prepared polymer blend, poly (3HT- Co - Th) - PMMA polymer blend films were prepared at different percentage weight ratios of the copolymerusing the casting method.The surface structure of the prepared copolymer wasanalyzed by using the Fouriertransform infrared (FT-IR) spectroscopyas well as the atomic force microscopy (AFM)technique.The optical absorbance (A) and the transmittance (T) spectra of the prepared films were measured by using the UV-Vis spectrophotometer in the wavelengthrange300 nm - 800 nm. These optical spectra were used to determine the main optical parameters of the polymer blend films. Resultsindicated that the prepared poly(3HT- Co - Th) - PMMA polymer blend films can be promising candidates for photonic and optoelectronic applications.
