Advanced Materials and Surfaces Group (AMSG)
Innovation through materials design and process development
The Advanced Materials & Surfaces Group (AMSG) was formally created in February 2004 with the arrival of Professor Martyn Pemble from the University of Salford, UK, where he held the post of Chair of Physical Chemistry. The current team has evolved since this period to gain global recognition through numerous national and international collaborative research projects. A wide range of advances in both industry relevant application areas and basic academic research fields have been achieved to date and ongoing investigations are equally ground breaking.
The AMSG team focus is essentially divided into two main research areas;
Thin films and surface structures, CVD, ALD and other novel deposition techniques.
Growth and modification of novel thin film systems and surface structures by chemical vapour deposition (CVD), atomic layer deposition (ALD) and variations of these methods including plasma-assisted ALD and liquid injection CVD. Most recently we have developed a roll-to-roll ALD system for the coating of textiles and other flexible materials.
Funded by SFI and Enterprise Ireland, this movie shows the roll-to-roll ALD system used to prepare coated textile materials with the primary aim of improving fire retardency but also for the creation of smart sensor technology (wearables) and anti-fouling materials that could have applications in the personal protective equipment area. The system performs one complete ALD cycle per pass under the heads and for demontration purposes the coating is built up by running the roller system backwards and forwards. The system operates at close to atmospheric pressure.
We have also recently begun to perform roll-to-roll coating of various polymer blends used in organic solar cells and light emitting devices.
Designed and built by our colleagues at the university of Sao Paolo, Brazil (Prof Roberto Faria, Mr Leonardo Dias-Cagnani and Ms Giovana Americo-Rosso), this system is currently being used to prepare organic photovoltaics (OPV) and organic LEDs (OLEDs) on flexible transparent polymeric materials. This work is funded by SFI International Strategic Cooperation Award (ISCA) Brazil for which Tyndall are the lead partners in the area of nanomaterials.
Photonic band gap materials
- Synthesis of novel particles and their self-assembly into photonic band gap materials, that are similar in structure to natural opals.
