Structure of polypropylene-based nanocomposites containing calcium zirconate
Polypropylene (PP) has recently been proposed as a good alternative to cross-linked polyethylene (XLPE) in the field of dielectrics due to PP's beneficial properties to withstand higher thermal endurance of up to 150°C along with its ability to be recycled with ease, when compared with XLPE. Ho...

| Summary: | Polypropylene (PP) has recently been proposed as a good alternative to cross-linked polyethylene (XLPE) in the field of dielectrics due to PP's beneficial properties to withstand higher thermal endurance of up to 150°C along with its ability to be recycled with ease, when compared with XLPE. However, PP is much stiffer than XLPE, making it unsuitable to be extruded as a high voltage cable insulation. Furthermore, PP has poor thermal conductivity under room temperature when compared with XLPE, which will otherwise result in inferior dielectric performances. Therefore, PP needs to be modified to alter its physical as well as electrical properties. In the current work, ethylene-propylene-diene monomer (EPDM) was proposed to be combined with PP to produce a PP blend with reduced overall stiffness. To increase the thermal conductivity of the PP blend, nanofillers were proposed to be added to the PP blend. For these reasons, the structure of the proposed materials was investigated by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). |
