Introduction to Nanoparticle Additives
Nanoparticle additives are materials at the nanoscale that are incorporated into products to enhance or impart specific properties. These additives are used across various industries, including healthcare, electronics, and materials science, to improve performance, durability, and functionality. The unique properties of nanoparticles, such as their large surface area to volume ratio and quantum effects, make them highly effective even in small quantities.What are Nanoparticle Additives?
Nanoparticle additives consist of nanosized particles that are typically less than 100 nanometers in at least one dimension. These particles can be made from a variety of materials, including metals, polymers, ceramics, and carbon-based substances. The small size and high surface area of these particles allow them to interact more effectively with their surroundings, leading to improved material properties.
