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, …

Constitutive modeling for macro-micro delamination for paperboard/Tow ards zero defects in packaging technology

The project aims to develop experimental methods for characterizing packaging materials. In the project, the microstructure of packaging materials w ill be methodically characterized and linked to mechanical properties. Traditionally, mechanical testing of paperboard material has been carried out without regard to micro-level mechanisms. With new experimental methods such as in situ x-ray tomography, much …

Process-adapted biobased assortments through novel development of the steam explosion process

The aim of the project is to, from softwood bark, develop and provide semi-manufactured industrial commodities with the following properties: a) Low content of process-disturbing/inhibitory substances during steam pretreatment  b) Enhanced enzymatic digestibility  c) High density and manageable properties for storage and transport Project partners: Swedish University of Agricultural Sciences, Valmet, Bio4Energy

Biocomposites-Materials modification to increase the processabilty at high fiber content

The current application aims at facilitating a substantial increase in the content of renewable lignocellulosic fibers in fiber reinforced wood fiber polymer composites (WFPL). The target is to enable production of WFPL’s with a fiber content >> 60%. For the forest based industries, this will create new market segments within construction, automotive and industrial goods, …

Green wood  adhesives based on side-streams from the pulp industry

In this project we propose to explore the use of side-streams originating from the pulp industry as adhesive binders for wood-based materials. The proposed project, aiming at developing novel, formaldehyde-free, adhesives from renewable resources, brings together experts in polymer/adhesive/wood chemistry with experts on forest/wood products and has the ability to gain novel, fundamental knowledge while …
