**5.4 Applications in coating materials**

Organic and inorganic composites based on alkoxy-lanes and alko-oxides have great uses in hard-coated eye glass lenses. The addition of NPs to epoxy silanes acts as a linker between organic and inorganic moieties that greatly enhance abrasion control without affecting the transparency of the glass material. Nanocomposites have also been developed for low surface free energy coatings. To add up in the mechanical properties, nanotubular materials are extensively used that gave strength to NCs where light weight and hardness are required for the resultant NCs. The use of nonlinear optics, including optical sensor protection from highintensity laser beams, flat panel displays, electromechanical actuators, lightemitting diodes, field-effect transistors, supercapacitors, and optical limiters are some applications of CNTs. Nanocomposites have provided significant advances over conventional NCs in tropical, mechanical, electrical, and barrier properties. Furthermore, it maintains transparency and reduces the flammability of the polymer matrix.
