| Popis: | In this work, in-situ synthesis method has been used for the first time to obtain poly(3-hexylthiophene)-antimony sulfide (P3HT–Sb2S3) composite materials. The Sb2S3 micro-rods are synthesized by microwave irradiation at temperature of 170 °C and power of 600 W. Then, P3HT–Sb2S3 composites are synthesized by in-situ polymerization of 3-hexylthiophene (3HT) monomers in the presence of different Sb2S3 micro-rod concentration (3HT/Sb2S3 weight ratio: 1/0.01, 1/0.03, and 1/0.05). The composite products are washed by centrifugation method to reduce the Sb2S3 loss in the composite materials. P3HT–Sb2S3 composite thin films are formed by spin coating. It is observed that the Sb2S3 incorporation in the P3HT polymer matrix increases the optical absorbance, head-to-tail (HT) dyads configuration, thermal stability, decomposition temperature, and photoconductivity of the composite products. Fourier-transform infrared spectroscopy (FT-IR), proton nuclear magnetic resonance (1H-NMR), and field emission scanning electron microscopy (FESEM) analyses show the Sb2S3 presence in the P3HT matrix and a strong interaction between P3HT and Sb2S3. The P3HT–Sb2S3 composite materials obtained in this work exhibit interesting optoelectronic properties that could be useful for device applications. |
