Polymer nano-composites have been studied as functional materials for many cutting-edge applications owing to the combination of good processibility of polymer and high functionality of nano-objects. Generally, the surface modifications of the nano- objects are required to ascertain a good dispersion of the objects in solvents and polymer matrices. Well-defined block copolymers having controlled number of functional groups can be used as surface modifiers for these purposes, where the block copolymers can be prepared through controlled polymerization techniques. In this presentation, various polystyrene based functional block copolymers were prepared through living radical polymerization technique, especially nitroxide mediated polymerization technique. The surfaces modifications of various nano-objects were demonstrated with the block copolymers, which resulted in improved dispersion of the nano-objects and better nano-composite properties. |
