Hybrid composites based on nanocellulose and 2D-materials
Nanocellulose in the form of fibrils (CNF) from wood is a new building-block for complex nanocomposites. Both the new materials and CNF itself are of major scientific and technical interest, with strong industrial potential. The use of colloidal systems makes it possible to mix CNF with for instance montmorillonite clay (MTM) or graphene oxide (GO) […]
Injection moulded polymers – imaging of composites with x-ray techniques
Investigation of the structure induced by processing of traditional polymers for packaging application (such as LDPE or HDPE) as well as new cellulose and ligno-cellulose based materials. Characterization include SAXS/WAXS imaging, birefringence, STXM, and CT.
The effect of compaction parameters on the properties of high-deformable paper
This project addresses the challenges of producing high-deformable paper for 3D forming applications using the in-plane compaction process. Enabling 3D forming of advanced paper structures paves the way for complete elimination of plastic based packaging or partial replacement of plastic in multi-material packages, which aligns with current international strategies for a sustainable development of the […]
Composite of lignin derivatives and conducting polymers for electro-capturing of toxic heavy metals
Among the 100% water on planet earth, less than 1% is liquid fresh water and about 0.0025% is available fresh water for drinking, food and industries. More than 90% of the fresh water is utilized for agriculture and industries. Pollution of water is thus an increasingly important problem. One of the most challenging depollution process […]
Production of new high-performance CNF biocomposites (Cellulose nano-composites)
The aim is to develop new methods for large-scale melt processing of thermoplastic composites reinforced with high content of cellulose nano-fibrils. The goal is a thermoplastic process capable of mixing and shaping thermoplastic compositions reinforced with 30 % or more nano-cellulose, obtaining a functional composite stiffness at least 10 times of the polymer matrix. Alternatively, […]
Processing & Mechanics – Bio-based Polymer Composite Materials
With this project, we aim to advance the understanding, synthesis, manufacturing and modelling of biocomposites. In particular, we target polymers reinforced with cellulose fibers that have been grafted with cellulose nano crystals, the wood-based cellulose fibers and nano crystals are an important resource from the Swedish forest industry. The idea is to scale up a […]
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, […]
Karakterisering och kvantifiering av deformations- och skademekanismer i kartong under komplexa belastningsfall
Projektets mål är karakterisering och kvantifiering av deformations- och skademekanismer i kartong under komplexa belastningsfall. Sådana är praktiskta viktiga vid konvertering av kartong i allmänhet, men speciellt betydelsefulla vid 3D-formning av geometriskt avancerade strukturer. För att nå målet ska experimentella 4D datortomografiundersökningar kombineras med matematisk modellering.
Porous, optical and IR-absorbing cellulose for solar evaporators
This project aims at investigating how conducting polymers interact with forest-based materials to form hierarchically nanostructured aerogels. We will develop protocols for fine tuning the structural and mechanical properties of cellulose-base conducting aerogels, and to control the penetration of solar absorbers (i.e. conducting polymers) in the nanostructured forest-based aerogels. We will study how energy is […]
New bio-based packaging and engineering plastics
The project is focused on the chemical design and development of new monomeric building blocks from lignin and cellulose feedstocks. These building blocks mainly include different cyclic diols, diesters, diamines, etc, to prepare mechanically rigid and thermally stable bio-based thermoplastics for use as high-performance packaging and engineering plastics.
Pre-project ForMAX beamline
This project is focused on SAXS measurements to study structuring of fibrilar systems under flow, such as 3D printing, electro spinning and fibre spinning. The project is in the framework of the feasibility study on the ForMAX beamline at MAX IV. Controlled alignment of for example cellulose nanofibrils is of high interest, since their mechanical […]
Soft cellulose-based robotics
The project is focused on the development of novel concepts for soft electromechanical actuators and robotics based on nanocellulose composites. Nanocellulose foams are light weight and compressible, making them ideal for functionalization for actuators. Magnetic and electronic functional composites will be developed and fabricated into novel device concepts. The project is part of WWSC.
