Professor Corrine Greyling


We are very fortunate to be having an introductory lecture by Prof Corinne Greyling from Technology Station in Clothing and Textiles, on technical textiles, conductive fibres and nanotechnology.

Professor Corrine Greyling was very fortunate to meet Prof MacDiarmid when she was working at Drexel University in Philadelphia for 3 months in 2001.   He was co-supervising some of the Drexel students graduate studies on electrospinning polyaniline into non-wovens.  There is a small chapter on electrospinning polyaniline and cyclic voltammetry measurements her PhD thesis (see download at http://scholar.sun.ac.za/handle/10019.1/3996 on pages 179 to 189).

Professor Greyling will be presenting the following:

1                    Metal fibres (extruded from metal wire)
2                    Metal fibres made from metal alkoxy precursors using sol-gel technology.
3                    Metal coated fibres using dipping and sol-gel technology.
4                    Conductive polymer fibres such as doped polyaniline or polyacetylene.
5                    Conductive fibres which are impregnated with metal particles / powders i.e. silver


Attached article which is the Nobel Prize lecture by Prof Alan MacDiarmid in 2000.  On the second page there is a graphic which shows that doped polyaniline can have a conductivity equal to copper.
