Nanocomposite Bio-materials

1. Nanocomposite Biomaterials

3. Decreased gas, water and hydrocarbon permeability

4. Flame retardancy

5. Thermal stability

6. Chemical resistance

7. Surface appearance

9. Polymer-matrix nanocomposites

10. Polymer – silicate nanocomposites

11. Elastomeric Nanocomposites

12. Bionanocomposites

14. In most cases, ceramic-matrix nanocomposites encompass a metal as the second component.

15. Ideally both components, the metallic one and the ceramic one, are finely dispersed in each other in order to elicit the particular nanoscopic properties.

17. These materials are better described by the term nanofilled polymer composites

20. Clay-polymer (nano-)composites

22. Examples are : muscovite, phlogopite, smectites

23. The aluminosilicate layers are held together by cations (usually alkali or earth alkali metals) in the interlayer.

24. The thickness of one such layer is approximately 1 nm.

26. The method of reactive encapsulation involves preorganization of an appropriate reactant by the active interior sites of a dendrimer molecule, followed by immobilization of the product with respect to the host.

28. Bionanocomposites add a new dimension to enhance the properties in that they are biocompatible and/or biodegradable materials.

30. Aliphatic Polyester Nanocomposites

31. Polypeptide-Based Nanocomposites

32. Smectite nanocomposites

33. Poly(urethane urea)

34. Polymer layered silicate nanocomposites
