Readily biodegradable vinyl polymers from biobased resources

The project aims at developing deep and relevant knowledge in polymer chemistry (monomer synthesis and polymerization procedures) and structure-property relationships (biodegradability and properties) with the aim to accelerate the capacity to transition into more sustainable materials. The main goals of the are: I. Design and synthesis of monomers that upon radical polymerization result in polymers with […]

Soft highly swelling fibres by alkali-activated chemical modification 

To make cellulose fibres more flexible and malleable, components inside the fibre must be properly modified, that is, the lignin, hemicellulose or cellulose needs to be at least partly transformed into a proper derivative. Several cellulose derivatives are today produced through chemical reactions that involves formation of ether bonds. To reach sufficient efficiency, these reactions

Processing of organosolv fractions for a functionalization and valorization in biobased materials

Optimization of organosolv wood fractioning is performed to obtain pulp containing cellulose, hemicellulose, andlow levels of lignin. The pulp is functionalized to achieve specific fibre properties, such as water stability. The functionalized fibres are evaluated in industrial partners’ products, i.e. biobased foams, to provide valuable feedback for optimization of the functionalization procedures based on industry

Plasticization and partial depolymerization of lignocellulose-based materials  

This project is a part of the competence center FibRe. This particular PhD student project aims to plasticize the lignin in the cell walls. The first part will be to extract lignin from wood and wheat straw, and to evaluate how different plasticizers affect the material properties. This will then be extrapolated to lignocellulose-based fibers.

Design for Circularity: Lignocellulosic based Thermoplastics – FibRe

Global warming is one of the largest threats ever to our planet which can completely alter our living conditions. Human contributions to emissions of green-house gases must decrease, and a drastically decreased use of fossil resources is a key step to achieve this. Daunting 320 million tons of plastics are annually produced in the world,
