  • 2. ORIGIN OF NANOCOMPOSITE <ul><li>Toyota central research labs in Japan teamed up with ube industries ltd, a Japanese resin supplier to produce a new composite polymer, consisting of Nylon-6 interspersed with layers of montmorillonite. </li></ul>
  • 3. IMPORTANCE OF NANO FILLER AND COMPOSITE <ul><li>“ NANO ” Appears to be the catch word today. </li></ul><ul><li>Why? </li></ul><ul><li>It has led to new developments of Materials science ,Polymer science ,Electronics and Bio – </li></ul><ul><li>Engineering, etc. </li></ul><ul><li>Same materials can be engineered for new properties :dramatic changes can be obtained by reducing the size. </li></ul>
  • 4. SIZE DEPENDENT PROPERTIES OF MATERIALS <ul><li>Material behave differently in form of Nano-size, Thin Films etc. </li></ul><ul><li>Size dependency of Electrical and Mechanical ,and Optical Properties. </li></ul><ul><li>Quantum size effects . </li></ul><ul><li>Structural changes induced by such dimensional control----Mechanical props. </li></ul><ul><li>Very high surface area made available. </li></ul>
