Nanocomposites are materials that combine a matrix, often a polymer, with nanoscale particles or fibers. These nanoparticles, which can be made from materials like carbon, silica, or metal oxides, enhance the properties of the composite, such as strength, durability, and thermal stability. The small size of the nanoparticles allows for a larger surface area, leading to improved interactions with the matrix. The unique characteristics of nanocomposites make them useful in various applications, including electronics, automotive, and aerospace industries. Researchers are continually exploring new formulations and methods to optimize their performance, aiming to create lighter, stronger, and more efficient materials for future technologies.
