**5.2 Applications of nanoclays**

Nanoclays improve the mechanical and physical characteristics of the filler and matrix optical interface, which is very helpful in eliminating pressures by improving the mechanical properties of nanocomposites. Due to the impressive mechanical properties, requirements, such as low filling, stiffness, low weight, and biodegradability of nanoparticle materials, make them ideal for enviro-compliant material development. Many researchers have focused on high-quality optimization, extraction, and machine performance by filling the matrix polymer with varying degrees. There are some challenges to the formation of NCs namely, severe dispersion of organo-solvents, agglomeration, and the presence of a hydrophilic environment.
