Lab-scale roll-to-roll ALD on textile by Tyndall

ALD growth is unstoppable - There is no end to it "The area certainly seems to show no sign of slowing down" as Maryn Pemble just commented on recent post regarding the latest growth forecast on ALD. Little did I know then while reading it the Tyndall just demonstrated ALD on textile in a spatial roll to roll machine! 

Last year I sat in a meeting with one of Europe's leading coating companies on the topic of ALD on textile and we discussed this topic back and forth if there is a market for it and if it can be done in a roll to roll system. Guess who I will be calling tomorrow morning!

Here are some textile/fibre related posts from the past year - ALD on textile is coming that´s for sure but do check out the video down below from Martyn Pemble and co-workers at Tyndall before!

From Youtube: This movie shows a lab-scale roll-to-roll atomic layer deposition (ALD) system which has been constructed at the Tyndall National Institute, University College Cork, Ireland, by Dr Shane O'Brien and Dr Ian Povey, using funding from Enterprise Ireland and Science Foundation Ireland.

Dr O'Brien and Dr Povey are based in the Advanced Materials and surfaces Group led by Prof Martyn E Pemble. The movie shows the textile sample moving forwards and backwards under the coating heads which supply the ALD precursors. The process is an example of so-called spatial ALD, whereby the precursors are separated spatially rather than in a temporal mode.

For further information please contact Prof Pemble using martyn.pemble@tyndall.ie or go to:

... and did you have enough? No, no I didm´t think so! It turns out that Prof. Pemble is involved in yet another roll to roll ALD project with a team from Sao Paolo, Brazil - check it out!

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 nano materials.
