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 […]
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 […]

Design and characterization of nanocellulose membranes to promote proton transport and selectivity for hydrogen fuel cells.
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, […]
Porous, optical and IR-absorbing cellulose for solar evaporators
This project aims at investigating how conducting polymers interact with forest-based materials to form hierarchically nanostructured aerogels. We will develop protocols for fine tuning the structural and mechanical properties of cellulose-base conducting aerogels, and to control the penetration of solar absorbers (i.e. conducting polymers) in the nanostructured forest-based aerogels. We will study how energy is […]
Soft cellulose-based robotics
The project is focused on the development of novel concepts for soft electromechanical actuators and robotics based on nanocellulose composites. Nanocellulose foams are light weight and compressible, making them ideal for functionalization for actuators. Magnetic and electronic functional composites will be developed and fabricated into novel device concepts. The project is part of WWSC.
Simulation and modelling of wood-based advanced functional materials
In this project we perform multi-scale theoretical modelling of wood-based materials and devices ranging from the Molecular Dynamics and ab initio simulations on the atomistic level to the drift-diffusion device simulation on the system level to answer the fundamental questions concerning material structure, morphology, polymerization, porosity, ion diffusion, role of water, solvents and many others, […]
Conductor patterns in wood and paper
This project is part of WWSC 2.0 at LiU. The project aims at investigating methods to modify cellulose-based materials such as paper to become electrically conductive, and moreover to do so in a spatially constrained way, in order to create conductor patterns. The long-term goal of the project is deriving 3D patterning and manufacturing techniques […]
