Workshop: How Rheology Can Be Used to Reduce Waste and Improve Formulation

25 April 2017

| £40


The workshop discusses the use of advanced rheological methods to improve the ink formulation and quality control for printed electronics based on the work funded by the EPSRC Centre for Innovative Manufacture of Large Area Electronics. It will discuss the benefits of the rheological methods and how these could be used in industry. There is scope for direct involvement in future work to implement these methods into industry.

Why use rheology?

By using the rheology, it is possible to improve the formulation of inks, especially functional materials where a high solids content is required, and to improve quality control. Taking a rheological profile for an ink is both faster and requires less material than performing print trials. Being able to assess the print quality, based on that information, will reduce the cost of formulating new inks and provide a quick and easy method for quality control. The rheology is also an independent parameter allowing it to account for changes in feed stock. The methods discussed can be implemented on many commercially available rheometers which are often under used.

How well does the rheology match to print performance?

There are a number of different parameters that can make up the rheological profile of an ink. The most commonly mentioned is the viscosity, but this alone does not produce a reliable correlation with print performance. To make full use of the rheology more advanced parameters were needed that can accurately be used to predict the print performance. The phase angle of the ink obtained using controlled stress parallel superposition methods can be related directly to the print quality and performance. Thus making it a critical parameter for both the formulation of new inks and quality control.

Who would benefit from attending this meeting?

  • Ink makers - Using rheology for faster and cheaper ink formulation and improved quality control
  • Printers - Using rheology to check for quality assurance and checking printability of older inks (reducing waste)
  • Other industry areas - The use of the new rheological methods to improve formulation will impact on more than just printed electronics. A full understanding of the rheology is also important for injection moulding, composites, food and more...

There is a £40+VAT fee for the event, this is to cover the cost of food.
