Abstract :

Over the past fifteen years both additive manufacturing and electrospinning have independently attracted increasing research interest. While additive manufacturing is now maturing to a commercial technology, electrospinning remains the focus of university-led research. Shortfalls within each technology, though, could be solved by overlapping each concept to produce new materials. Some of the limitations of additive manufacturing include lower resolution fabrication limits while electrospinning is unable to accurately make three-dimensional products.

Electrospinning, the electrostatic drawing of fibers, promised to revolutionize the fields of medicine and textiles in particular. Now, after generating an exponentially increasing number of scientific publications over the past decade, enthusiasm for electrospinning has been tempered somewhat by the “underwhelming nature” of the first products. However, there are still many reasons why electrospinning is an important manufacturing process; it is inexpensive, can be applied to many different polymers and contains diverse aspects that are only now being researched - new electrospinning products are being described in the literature daily.

This seminar describes the technique of electrospinning, focussing on the automation of the process and how this allows a new generation of complex medical materials to be produced.

Biography :

Dr. Paul Dalton has more than 15 years’ of interdisciplinary experience in biomedical materials. He was educated as a materials scientist, but performed research other fields such as neuroimmunology and medical devices. Paul was awarded his PhD from Curtin University in Perth, Australia, where he was part of a team taking an artificial cornea from concept to the clinic. He took on post-doctoral positions at the University of Toronto, Canada, and Aachen University, Germany, between 1999 and 2005, developing hydrogels for nerve regeneration and applying nanotechnology to life science applications. He was an independent research fellow at the University of Southampton from 2006 to 2008, investigating the neuroinflammatory properties of hydrogels in the spinal cord. Since 2009 he has split his time between Shanghai Jiao Tong University in China and Queensland University of Technology in Australia. Paul has published over 50 research articles in journals that include Advanced Materials, Progress in Polymer Science and Nature Materials.
