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 […]

Mass transport in wood components from processed woods(III-3)

TREESEARCH

Purpose of the project is to study mass transport of ionic liquids into wood pieces and fibers and consequent lignin and hemicellulose transport out from the pieces. Therefore, characterisation techniques to investigate the location of ionic liquids and lignin in the fiber structure are needed to be developed. Examples of such techniques are X-ray imaging,

In-situ polymerization of functional polymers within the fiber cell wall

TREESEARCH

In this project, the fiber wall is modified to enable diffusion of functional monomers and subsequent polymerization and crosslinking within the wet-fiber wall resulting in a stiff and elastic fiber-composite. The fibers are modified in a fully biobased system and the end material is biocompatible and degradable.

Wood modification towards hierarchical catalyst

TREESEARCH

Electrocatalytic reaction is a green technology for sustainable energy conversion, materials design, environment remediation, and green chemistry, where the role of catalyst is essential. Hierarchical structures combining multi-scale pores are favorable due to combined high specific surface area, mass diffusion in the structure and accessibility to the surface. In nature, biological materials are much more

Wood-based barriers for wood-based materials

TREESEARCH

Paper/wood-based materials suffer from poor barrier and moisture-sensitive properties (left figure). By learning how nature (plants/fruits) create moisture and gas barriers, we have developed crosslinked barrier biopolyesters (representing the cutin layer in plants) with also a process that yields a rough wax-like outer layer, similar to what is observed in plants, giving high surface hydrophobicity
