PhD Research Title: Electrically Conductive Adhesives for Use in High Moisture Environments

Electrically conductive adhesives (ECAs) are widely used as a low temperature joining technology for the interconnection of electrical and electronic components in applications ranging from flat screen display panels to RFID tags and photovoltaic power generation. ECAs are usually based on metallic particle fillers that provide the electrical conductivity through particle-to-particle contacts and a surrounding polymer matrix that provides structural integrity and adhesion. Increasingly, there is a desire to use these materials in more demanding environments, such as where there are high levels of moisture and/or extremes of temperature, and this places demands on their long term mechanical integrity, adhesive bonding capabilities and electrical resistivity.

The aim of this project is to investigate the reliability and failure mechanisms of electrically conductive adhesives when exposed to high levels of moisture. This will be carried out in the context of a number of potential applications where it would be desirable to use ECAs as an alternative or enabling joining technology. Silver flake is used as the filler in many ECAs and the research will also consider how alternative fillers may be substituted in to the formulation and how this will affect the adhesive reliability, cost and environmental impacts.
