Nanocomposites is a research domain within materials science and engineering dedicated to the design, synthesis, characterization, and application of multiphase materials wherein at least one constituent phase exhibits nanoscale dimensions (typically in the range of 1-100 nm). This field investigates how the unique interfacial area and quantum effects arising from the nanoscale morphology significantly influence and often enhance the overall properties and performance of the composite system compared to conventional materials, driving innovation across diverse technological applications.
