Abstract
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.
Highlights
Thiopheneis a based polymer material can be used for different applications in the photonic and optoelectronic devices such as, light emitting diodes (LED’s), solar cells, optical sensors, optical switching, and optical power limiting [1 - 12]
The poly(3HT - Co - Th) - Poly(methyl methacrylate) (PMMA) polymer blend films were prepared at different weight ratios of the copolymer poly(3HT - Co - Th), that formed from the monomers thiophene (Th) and 3 - hexylthiophene (3 - HT) by the addition polymerization method
It is clearly noticed that the surface roughness average of the prepared polymer blend film decreased when the percentage ratio of the copolymer poly(3HT - Co - Th) increased from 0.033 % to 0.046 %, and starts to increase as the percentage ratio increased to 0.060 %
