Self-Assembly of Polymers

Polymer self-assembly - a spontaneous process driven by non-covalent interactions – is commonly used to obtain ordered structures with different morphologies and properties at nanometer length scales. The dynamic nature of non-covalent interactions allows these self-assembled structures to respond chemically or structurally to environmental changes which are quite important in various applications such as drug release, drug delivery, tissue engineering in the biomedical area, and sensors, multi-functional coatings and catalysis in material technologies. Complexation-induced self-assembly of block copolymers has also been demonstrated to be effective in tuning the morphology and the properties of various polymeric systems such as nanoporous materials, smart membranes and proton conducting materials.
