nanokomposiititjä

Nanokomposiitit refer to composite materials that incorporate nanomaterials as at least one of their phases. Typically, a nanokomposiitti consists of a matrix material, which can be a polymer, metal, or ceramic, reinforced with nanoparticles. These nanoparticles, with at least one dimension in the nanoscale (1 to 100 nanometers), can include carbon nanotubes, graphene, nanoclays, or metal oxide nanoparticles. The inclusion of these nanoscale fillers significantly alters the properties of the bulk material compared to its conventional counterpart.

The enhanced properties observed in nanokomposiitit stem from the high surface area-to-volume ratio of the nanoparticles. This large interface between the nanoparticles and the matrix allows for more efficient load transfer and interaction, leading to improvements in mechanical strength, stiffness, thermal stability, and electrical conductivity. For instance, polymer nanokomposiitit often exhibit superior tensile strength and fracture toughness even with a very low percentage of nanofiller loading.

Applications for nanokomposiitit are diverse and continue to expand. They are found in industries such as aerospace, automotive, electronics, and biomedicine. In the automotive sector, they can be used to create lighter and stronger components, improving fuel efficiency. In electronics, their unique electrical properties make them suitable for advanced sensors and conductive coatings. The development of nanokomposiitit represents a significant advancement in materials science, offering tailored properties for a wide range of technological needs.
