What are Polymers?
Polymers are long-chain molecules composed of repeating structural units called monomers. These can be either natural, like cellulose and proteins, or synthetic, like polystyrene and polyethylene. Polymers are widely used in various industries due to their versatility, durability, and lightweight properties.
What are Nanocomposites?
Nanocomposites are materials that incorporate
nanoparticles into a polymer matrix to enhance or add new properties. The nanoparticles usually have at least one dimension in the nanometer range (1-100 nm). This integration can significantly improve mechanical, thermal, electrical, and barrier properties of the base polymer.
