Molecularly designed cellulose materials for triboelectric applications

Cellulose films possesses favorable triboelectric properties otherwise only found in synthetic, oil-based polymer materials. This can open up entirely new possibilities within the area of internet-of-things (IoT), which is expected to grow significantly in the coming decades. Cheap and sustainable sensor devices based on renewable, self-electrified systems without the need of batteries, self-powered by insignificant […]

Physical properties characterization of cellulose biocomposites

Advanced cellulose-based biocomposites are bio-degenerable mateirals for a sustainable material. These materials generally have complicated and highly heterogeneous optical and mechanical properties. The developments and applications of such materials demand a thorough investigation of their physical properties and their structure-property relationship. This project aims to characterize the optical and mechanical properties using experiments and simulation.

Electroactive Cellulose Composites Towards Future Green Devices

In the last few decades, significant interest has arisen in the use of cellulose in conjunction with electrically conductive materials for a wide range of applications, from energy storage and actuators to sensors. The primary driving force for selecting cellulosic materials stems from their intrinsic and extrinsic properties, such as high flexibility, processability, chemical stability,

Nanostructured composites from latex nanoparticles 

Latex nanoparticles with controllable physico-chemical properties, such as size, rigidity and surface functionality, have shown great promise in modifying and tailoring macroscopic properties of cellulosic nanomaterials. For instance, it has been found that cationic nanoparticles can stiffen or plasticize cellulose nanopapers depending on additive amount. The impact of nanoparticle shell functionality will be further investigated

Återanvändning av matavfall för att konstruera svampmembran och filter för vatten- och luftrening

Filter och membran är halvgenomsläppliga barriärer, som ofta produceras från fossilbaserade polymerer och används för luft- och vattenrening. Membranfiltreringsanläggningar drabbas av omfattande membranbeläggningar, vilket kräver frekvent membranbyte. Detta medför en stor mängd plastavfall. Å andra sidan, har coronapandemin lett till en dramatisk ökning engångsmasker och flera miljarder masker slängs varje dag. Miljövänliga alternativ krävs för

Design of biochar from residual streams – influence of fuel and process parameters on biochar properties for water and soil applications

Biochar can be used in many applications, including water treatment and soil improvement. The properties of biochar are affected by the conditions during production. In this project, the influence on the properties of the biochar at different process conditions is investigated through the gasification of residual streams from both the forestry and agricultural sectors. The

Enzymatic engineering of hemicellulose hydrogels

In this project we will engineer hemicellulose hydrogels using a wide range of enzymes, from oxidative laccases that introduce crosslinking to specific hydrolases that cleave selectively side chains from the hemicelluloses. We expect that the enzymatic treatments will modulate the network interactions in the hydrogels and the rheological properties. We will investigate the morphology and
