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 …

Comprehensive Review of Membrane Fouling Control Mechanisms
Abstract: One of the biggest problems with membrane-based separation procedures is membrane fouling. As particles, organic matter, microbes, and other materials build up on the membrane’s surface or inside its pores, the effectiveness of membranes – such as those used in reverse osmosis, ultrafiltration, and microfiltration – declines over time. The effectiveness and longevity of the membrane are eventually lowered because of this fouling, which causes a drop in flux and …
