Self-healing Polymer Nanocomposites study using filler effect
Abstract: Polymers, while versatile, often lack the desired mechanical strength, thermal stability, or barrier properties for high-performance applications. This limitation is elegantly addressed by creating polymer nanocomposites. These materials are formed by incorporating small amounts (typically 1-5 wt%) of nanoscale fillers (e.g., carbon nanotubes, graphene, silica, clay, metal oxide nanoparticles) into a polymer matrix. The magic of nanocomposites lies in the incredibly high surface area-to-volume ratio of the nanoparticles and their …

Several Phases of Binary Liquid Mixture
Abstract: The system’s overall composition, heat, and stress can all be changed independently. Instead of using parameters like the coordinates of a three-dimensional phase diagram, we often generate a twodimensional phase transformation that is either a thermal diagram at a specified pressure or its composition graph at a fixed temperature. The location of the system points on one of these diagrams correlates to a certain heat, stress, and normal phenomenon. As …
