Electrospinning of Polymeric Nanofibers and Nanocomposite Materials: Fabrication, Physicochemical Characterization and Medical Applications

In the present thesis, varieties of electrospun nanofibrous scaffolds and nanocomposite that mimic the nanostructure and composition of native extra cellular matrix (ECM) have been prepared for future application in medical uses (e.g. drug delivery, bone regeneration, skin substitute and dentistry). Detailed studies of the changes in physico-chemical properties that take place during electrospinning of the polymeric materials have been investigated. The results demonstrated that the fiber diameter influences its micromechanical deformation. In addition, the macromolecular orientation and molecular mobility of the brittle polystyrene nanofibers were enhanced by reducing the fiber diameters. The miscibility of the blend polymers have been enhanced by decreasing the fiber diameters. Moreover, the electrospun blend nanofibers have been used as a compatiblizer to increase the contact between non compatible polymers for dentistry applications.
