Modelling of conductive polymer-redox polymer supercapacitors
The Laboratory of Organic Electronics is developing cellulose base conductive polymer-redox polymer supercapacitors for large scale energy storage. This project focus on the modelling of such systems by coupling a recently developed theoretical model for organic mixed electronic-ionic conductors with the redox chemistry of wood-based redox polymer for energy storage applications. The aim is to […]

Conducting polymers-modified wood composites
In this project, we used different conducting polymers to impregnate the wood. Our goal is to create a pathway for studying the nano/microscopic structure of the conductive wood and the interactions between the wood components and the conducting polymer matrix. . In detail, we mainly focus on the difference of crystallinity and the orientation of […]
HEALIX
This project is about development of novel wound dressing materials and we are making cellulose nanofiber hydrogels from wood as raw material.
H2O2 – Fuel and Energy Technology for the Future
Researching all-organic photo- and electro-catalysis to explore novel pathways to produce hydrogen peroxide, H2O2, and convert this fuel into electricity with a novel fuel cell technology. In order to achieve high-rate and large-volume production of H2O2 and conversion into electricity, we suggest to research and develop a novel catalytic paper electrode technology. These paper electrodes […]
Controlling product characteristics on board machine utilization process data
Quality on any board and paper products is dependent on being able to maintain low variability within product characteristics. A common problem is that these characteristics are measured cannot be measured online in the production, and is the time resolution will therefor be very low. The product characteristics will be dependent on the process characteristics, where […]
Forest-based materials for optoelectronic devices
We explore the use and development of forest-based materials in organic and hybrid organic optoelectronic devices. We carry out fundamental materials studies combined with device design, fabrication and characterization.
Cellulose proton selective membrane “Cellfion”
Design and characterization of nanocellulose membranes to promote proton transport and selectivity for hydrogen fuel cells.
Low density and wet stable networks of cellulose nanofibrils with a tailored 3D shape for advanced applications
The project has the following purpose and aims: (a) Novel wet-stable, low density networks of cellulose nanofibrils (CNF) with a tailored 3D structure; (b) Tailored structures through controlled freeze-linking of the CNF followed by a formation of interpenetrated polymeric networks inside the cellulose network for controlled liquid spreading and liquid holding capacity; (c) Tailored 3D […]
EPIC – elektro- och fotokatalys inducerat i papper
Den vanligaste metoden att framställa papper görs genom den så kallade Kraft-processen. I denna process tas olika komponenter bort från träet för att möjliggöra vidare framställning av högkvalitativ cellulosa och papper. En viktig del i Kraft-processen är den så kallade avlignifieringen. Under denna process öppnas cellulosaväggen och porer av storleken från 20 till 50 nanometer […]
Composite of lignin derivatives and conducting polymers for electro-capturing of toxic heavy metals
Among the 100% water on planet earth, less than 1% is liquid fresh water and about 0.0025% is available fresh water for drinking, food and industries. More than 90% of the fresh water is utilized for agriculture and industries. Pollution of water is thus an increasingly important problem. One of the most challenging depollution process […]
Lignosulfonate composited with electronic polymers for large scale energy storage applications
A renewable resource from existing forest industry is the black liquor that mainly goes to combustion. The dominating biopolymer in black liquor is a derivative of lignin. At LiU we have shown how lignin and lignosulfonate (LS) can be used to store charge into biopolymer electrodes, and built supercapacitors/supercabatteries of such electrodes. In these electrodes, […]
