The bio-feedstock of tomorrow for controlled and reversible chemical modification on the macro and microfiber level
Itaconic acid, a di-carboxylic acid produced from citric acid or fermentation of sugars, is predicted to become a valuable bio-based chemical for the future, making it interesting for applications in cellulose based functional materials. This project will investigate the tailored modification of Bleached Kraft Pulp (BKP) with itaconic derivatives. Since the reactivity to a large […]
PolyTree
The main goal of this project called PolyTree is to enable a closed-loop sustainable materials economy by making renewable polyesters from wood-based building blocks through innovative green chemistries. While biopolymers have been actively developed, their technical properties lack in respect to fossil-based materials. Moreover, biopolymers are not necessarily biodegradable – or recyclable. This project embraces […]
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 […]
Cellulose-based triboelectric filters for airborne particles (Tribofilter)
The project aims to design and investigate a novel cellulose-based filter material with high particle retention and low-pressure drop based on triboelectric effect. The developed material is thought to act as a self-charging electrofilter that retains polluting particles harmful to humans.Air pollution caused by particulate matters (PMs) has raised serious concerns due to their threats […]
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 […]
