Fabricating and examining nanocomposite of P3HT- Graphene- MoS2 by laser ablation method

Abstract

Abstract This study presents the first successful synthesis of a nanocomposite comprising Poly (3-hexylthiophene) (P3HT), graphene (G), and molybdenum disulfide (MoS2) via laser ablation, using a Q-switch Nd-YAG laser with a repetition rate of 1 (Hz) and different laser pulses of 200, 500, and 800 for both graphene and MoS2, the morphological and optical properties of the samples was thoroughly investigated by various analytical techniques including Transmission electron microscopy (TEM), atomic force microscopy (AFM), Fourier transform infrared (FTIR), and spectrophotometer UV-Vis. Transmission electron microscopy showed that the graphene and molybdenum nanoparticles were semispherical or ball-shaped, with diameters ranging from 6.7 to 61.7 nm. The UV-Vis findings show that the absorbance and absorption coefficient increase with the number of pulses due to the increased concentration of nanoparticles. The FTIR results confirm strong bonding between the P3HT-G800P/MoS2 800P nanocomposite bonds. The indirect energy gap of the Nanocomposite is estimated to be 1.99 (eV), making it attractive for optoelectronic applications.
