1T phase dominant hybrid 1T/2H@MoS2/PEDOT:PSS nanocomposites for potential charge transport applications
Molybdenum disulfide (MoS2)/Poly (3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT: PSS) nanocomposites have attracted a great deal of interest in the area of organic electronics and optoelectronics due to their exceptional conducting nature. In this work, we present a novel hydrothermal method for synthesis of 1T phase dominant hybrid-phase MoS2 nanosheets and its synergic properties with PEDOT:PSS to facilitate improved charge transport with better 1T phase stability. The prepared nanocomposites are characterized by X-ray diffraction (XRD), Field Emission Scanning Electron Microscope (FESEM), Transmission Electron Microscopy (TEM), UV–visible (UV–Vis) absorption spectroscopy, Photoluminescence (PL) spectroscopy, Fourier Transform Infrared (FTIR) spectroscopy, Raman spectroscopy and X-ray Photoelectron (XPS) spectroscopy. XRD spectra of MoS2 show peaks at 2θ values of 9.16°, 17.4°, 33.3° and 57.5° corresponding to different planes of both 1T and 2H phases. The FESEM images reveal the flower-like MoS2 of approximate diameter ~ 670 nm consists of numerous curly nanosheets stacked together. TEM images reveal corrugated nanosheet structures with distinct lattice fringes. The UV–Vis spectra of MoS2 shows a broad absorption in the range ~ 210–280 nm, with two other broad peaks at ~ 690 nm and ~ 1012 nm. Raman and XPS spectroscopy confirm formation of 1T-dominated mixed phase (1T/2H@MoS2) nanosheets. Conductivity measurements using I–V graphs show enhanced conductivity for the nanocomposite up to 1.3 s/m in comparison to pristine MoS2 and PEDOT:PSS polymer.
期刊介绍：
The Journal of Materials Science publishes reviews, full-length papers, and short Communications recording original research results on, or techniques for studying the relationship between structure, properties, and uses of materials. The subjects are seen from international and interdisciplinary perspectives covering areas including metals, ceramics, glasses, polymers, electrical materials, composite materials, fibers, nanostructured materials, nanocomposites, and biological and biomedical materials. The Journal of Materials Science is now firmly established as the leading source of primary communication for scientists investigating the structure and properties of all engineering materials.
