Low-cost cellulose-based membrane can be used in energy harvesting devices

Low-cost cellulose-based membrane can be used in energy harvesting devices

Hongli Yang is a doctoral student at the Digital Cellulose Center, and with her latest research, she has created a highly conductive, low-cost nanocellulose-based ionic membrane. The new membrane is promising for electrochemical energy technology, such as redox flow batteries. The abundant natural resource of cellulose, combined with a simple production process makes the new membrane low-cost compared to the current commercial non-biodegradable membrane.The research within the Digital...

Laser Induced Graphene from Wood Ink – Published!

Laser Induced Graphene from Wood Ink – Published!

A new publication by RISE (Research Institutes of Sweden) researchers within the Digital Cellulose Center has been released online in the journal npj Flexible Electronics. The report outlines how to create an electrically conducting material from a wood-based ink. The ink is environmentally friendly and sustainable being composed of lignin and cellulose from wood and dissolved in water. After the ink is deposited via screen-printing a laser is used to...

Grey scale and paper displays – Manuscript published!

Researchers from Linkoping University and RISE Acreo have collaborated on a project to produce greyscale and paper displays using conductive polymers and a UV-patterning technique. The displays rely on the electrochromic properties of the materials meaning the display will change with the onset of an applied voltage. The authors use a vapor synthesis technique and photomasks to embed images into conductive polymers which appear and disappear...
