摘要

This article introduces an industrially viable approach to enhance polypropylene (PP) using melt intercalation nanoclay (NC) blends evaluated through advanced correlation analysis. The study investigates the mechanical and thermal properties of polypropylene reinforced with nanoclay at varying weight fractions (1, 2, 3, and 4%) to produce PP/NC nanocomposites via injection molding. The mechanical performance, including tensile strength, modulus, and hardness, was evaluated using a tensile testing machine and nanoindentation, while the thermal properties were characterized using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) provided insights into the chemical and morphological characteristics of the composites. The results verified enhanced mechanical properties with increased NC percentage. TGA revealed improved thermal resistance for the 4 wt.% NC blend, whereas DSC analysis indicated no significant changes in melting temperature across all blends. SEM imaging confirmed a uniform distribution and strong interfacial adhesion between PP and NC, corroborated by FTIR analysis. These results highlight the potential of NC reinforcement to enhance the properties of PP for advanced material applications.
