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