Event details

Conducting polymers offer the optical, magnetic and electrical properties of metals whilst retaining the mechanical properties and processing advantages of polymers. Conducting polymer thin films and micropatterns are frequently used in commercial applications, such as microelectrode arrays in chemical sensing devices. However, the applications are limited due to lack of simple inexpensive methods to create reproducible micropatterns.

The indole 5 carboxylic acid asymmetric trimer was selected because it has a large conducting p backbone, it is inert and relatively soluble. Soft lithography techniques have been developed to create high quality reproducible indole microtracks of various dimensions of this molecule on functionalised glass surfaces.

This talk includes an introduction to conducting polymers and the indole 5 carboxylic acid trimer and a detailed discussion of the soft lithography techniques used, illustrated with various SEM images of the indole micropatterns formed using these techniques.

About Condensed Matter lunchtime seminars

This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
