  • 20. Conclusion 20  Today, demand for thermoplastic polyolefin/polypropylene nanocomposites has moved beyond nylon 6/clay nanocomposites, mainly because of their low cost and enhanced physico-mechanical properties.
  • 21. Conclusion 21  In the past, the automotive industry was more inclined towards using nylon 6/clay nanocomposites for under-the-hood applications, where higher heat deflection temperature, enhanced stiffness, and light weight were the goals.
  • 22. Conclusion 22  The performance-to-cost ratio was a main constraint which halted the rapid growth of polymer nanocomposites. However, nylon 6/clay nanocomposites (more costly) are still used for under the hood applications, fuel lines and fuel system components.
