Thermal and Optical Properties of Polystyrene Nanocomposites Reinforced with Soot

Abstract

Heat stabilizer plays a major rule in the manufacturing of plastic products to enhance thermal properties. Carbon nanostructures (include soot) is one of the famous heat stabilizers. In the present study, different ratios of soot were blended to polystyrene (PS) using magnetic-heater stirrer and the ultrasound machine. The casting method was used to prepare the thin films of the pure and blended polystyrene. The techniques such as Fourier Transform Infrared Spectroscopy (FTIR), thermogravimetric analysis (TGA) and UV-Visible spectrophotometer were successfully used to characterize as-prepared composites. TGA results show that the thermal stability of PS is increased significantly after the addition of soot to polystyrene . The initial decomposition temperature (5% weight loss) of PS (229°C) is increased to 395°C when loading 5% (wt/wt) of soot. Differential thermal analysis (DTA) curves of composites represented higher temperature peak 452.23°C, and less degradation rate than virgin polystyrene. In addition, the optical results of polystyrene composite showed decreasing in the energy gap, values of refractive index and the real part of dielectric constant when the soot was added to polystyrene.

Carbon Soot Polymer Nanocomposites (CSPNCs): Production, Surface Morphological, Glass Transition Temperature Phenomenon and Optical Properties

“…Dynamic mechanical analysis is an amazing tool to study the viscoelastic properties of carbon soot particles filled with polymer. The other authors investigated the mechanical properties of carbon nanoparticles with polymer [48][49][50][51][52][53]. The dynamical mechanical results of carbon soot/polystyrene nanocomposites produced by solution casting method for pure polystyrene, almond soot/polystyrene and mustard soot/polystyrene at 1 and 2 wt% concentrations (Figure 30) show that for all CS/PS nanocomposites there is a downshift in viscous modulus toward a higher temperature compared to the pure polystyrene.…”

“…[4][5][6] Meanwhile, PS is a polymer material that is widely used as packaging and household appliances such as disposable cutlery, bottle and caps, cups, trays, containers, and CD protectors. [7][8][9] Unlike PCL, PS is a material that is difficult to decompose so that it contributes to environmental damage. 10 11,12 Whereas, PCL has the good mechanical properties, semicrystalline, biodegradable, biocompatibility, nontoxic and permeability.…”
