DESCRIPTION
In the context of Macromolecular Engineering our research activities can be classified as follows:
Design of model macromolecules, i.e. synthesis and characterization of polymers of tunable macromolecular characteristics and functionality via “living” polymerization methods.
Fabrication of nanostructured polymeric materials in the solid state and polymer/carbon nanotubes or graphene nanohybrids.
Study of association phenomena and self-assembly of model amphiphilic block copolymers of various macromolecular architecture e.g. ABA ABC, CBABC, A(B-co-C), AnBn and An(B-C)n stars.
Design of stimuli responsive model block copolymers in aqueous media: multi-compartment micelles and injectable reversible hydrogels responsive to pH, ionic strength and temperature.
Design of Block copolymers of specific architecture (e.g. linear, star-shaped etc) bearing biocompatible (e.g. polypeptides) and/or biodegradable segments, capable to form self-assemblies (micelles or transient networks) in aqueous environments in order to be used as drug nanocarriers suitable for controlled drug delivery potential applications.
