Seminar - Electrospinning Nanofibres/Nanocomposites: An Alternative Material Fabrication by Dr. Yu Dong

Date:   26 September 2013 (Thursday)

Time:   11:00 am – 12:00 pm

Venue:  EF305, The Hong Kong Polytechnic University

Abstract:

In Recent years, the popularity of electrospinning used in nanotechnology areas has increased substantially for producing cost-effective and continuous nanofibres owing to its enormous innovative applications in range of tissue engineering, construction and building structures, drug delivery, cosmetic membranes, nanofiltration and military protective clothing. The size effect of electrospun fibres is of particular concern in that the significant reduction of fibre diameter down to the nanoscaled level enables to produce fibre networks with large fibre aspect ratio, high specific area and porosity. These structural merits are very crucial for the enhancement of mechanical properties of fibrous structures, the cell growth in tissue scaffolds, as well as the acceleration of drug release.

This presentation comprises two critical aspects of electrospinning nanofibres/nanocomposites in multi-view of research, namely process optimisation of elecrospinning using design of experiments for improved material performance and application of electrospun nanifibres/nanocomposites for effective drug delivery. It is anticipated that this work can shed some light on the future implementation of electrospinning for the advancement of fibre/composite fabrication and manufacture on a wider scale.
