Synthesis of 2D Molybdenum Disulfide (MoS2) for enhancement of mechanical and electrical properties of polystyrene (PS) polymer
In this research article, ultrasound assisted exfoliation in a liquid phase production process has been adopted for synthesis of 2D Molybdenum Disulfide (MoS2). The energetic governing dispersion of Nano sheets in a wide range of solvents has been studied. Nano sheets dispersion in an aqueous media has been prepared with the help of high surface tension solvents like N-Methyl-1, 2-Pyyrolidone (NMP) and Tetrahydrofuran (THF). The dispersion was composed of layers of MoS2 with some quantities of mono and bi-layer materials were observed. Scanning Electron Microscopy (SEM), X-Rays Diffractometry (XRD), Transmission Electron Microscopy (TEM) and Atomic Force Microscopy (AFM) were used to characterize the samples; SEM clearly evident the microstructure of samples while XRD shows the peaks of filler in the polystyrene composite membrane. AFM confirmed the presence of 2D MoS2 with 0.9-7 nm thickness range of MoS2 flake. In order to get the surfactant stabilized dispersed material, the processing was enhanced using prolonged sonication to yield maximized concentration. Liquid phase exfoliation allows dispersion to be cast into thin film by using vacuum filtration assembly. The obtained film is dispersed in solvent and is used in polymers. Two sets of concentrations (0.01, 0.03, 0.05 and 0.07% by wt. and 0.1, 0.3, 0.7 and 0.9% by wt.) were analyzed and it was observed during tensile testing that modulus of elasticity (E), percentage elongation and ultimate tensile strength (TITS) of composite material increases maximum up to 741times, 374 times and 200 times as compared to base polymer (PS), respectively. Furthermore, dielectric constant, dielectric loss and electrical conductivity of PS-MoS2 were also evaluated and finding clearly pointed out that filler loading of MoS2 has considerable effects on these properties and maximum value of dielectric constant is 3.6 at 0.9% loading as compared with of pure PS (polystyrene) matrix. On the other hand, variation in dielectric loss from lower to higher frequency is 2.5 x 10(-2) on average which is not so significant. Electrical conductivity was also accounted, and measurement results are indicating that conductivity was almost constant at lower frequency in range of 10(-19) due to low field strength, but it increases to 10(-9) value at higher frequency due to hoping mechanism and network formation of filler.
