From fundamental research to pilot scale – the material that can replace polystyrene foam

Professor Lars Wågberg tells kth.se about the first steps and the research that led to a foam material, by then made of nanocellulose. The first steps were taken as a doctoral thesis within the research center Wallenberg Wood Science Center and in 2012, doctoral student Nicholas Cervin was able to present his thesis. – It …

Article in Forskning & Framsteg highlights new materials from wood

The transparent wood is an example that the magazine Forskning & Framsteg brings up. The picture is taken in a different context. The article focuses on the expression “Everything that is made of oil can be made of forest” and then shows exciting examples of both research and development projects. Participating in the article are …

Aerogels of nanocellulose is an extremely leightweight  type of material. The photo shows an aerogel on a part of a flower.

Nanocellulose aerogels for future biomedical applications

Nanocellulose aerogels are a relatively new type of lightweight material where around 99% of the material consists of air. Research has shown the potential for nanocellulose arogels, among other things, for high-performance insulation and purification of water, but the process of making them has required special equipment such as shock freezing with liquid nitrogen followed …

Next generation transparent wood is here – 100% biobased

Much has happened since the first publication on the transparent wood; a bio composite that combines transparent properties with the strength of wood. Since 2016 the material has been given special properties such as thermo-regulation and other intelligent properties. Now a new milestone has been reached: fully bio-based transparent wood, made with green chemistry. – We …

conductive cellulose yarn is used in a sewing machine

Electronically conductive cellulose-yarn developed by WWSC researchers

The yarns were produced by a roll-to-roll coating process with an ink based on the biocompatible PEDOT:PSS and could be used in a household sewing machine. The findings were recently published in ACS Applied Materials & Interfaces. “This cellulose thread could lead to garments with built-in electronic, smart functions, made from non-toxic, renewable and natural materials,” …
