Wood-based barriers for wood-based materials

Paper/wood-based materials suffer from poor barrier and moisture-sensitive properties (left figure). By learning how nature (plants/fruits) create moisture and gas barriers, we have developed crosslinked barrier biopolyesters (representing the cutin layer in plants) with also a process that yields a rough wax-like outer layer, similar to what is observed in plants, giving high surface hydrophobicity […]

Förhorning av träfibrer

Projektet går ut på att genom experimentella studier bygga upp en kunskap kring förhorning av komponenterna i träfibrer. Förhorning är ett fenomen där, i nuläget praktiskt sett irreversibla, processer i samband med torkning förändrar fibrernas svällning och flexibilitet och därmed bindningsförmåga. Bindningsförmågan till andra fibrer har stor inverkan på hur starka fibernätverk kan skapas och

Energy efficiency and modelling of vacuum dewatering in modern tissue machines

The project is a research coproduction between the research environment Pro2BE at Karlstad University, Valmet and Albany International about energy efficiency of tissue production. The project is aimed at acquiring deeper knowledge about tissue vacuum dewatering and at modelling vacuum dewatering during tissue production, both with a conventional tissue manufacturing method (DCT) and with Through

Biobased barriers on packaging substrates

The PhD project in chemical engineering will use wood-pulp fibres, modified cellulosic materials, dewatering and drying as well as computational fluid dynamics, mass transfer models, rheological characterization of complex fluids and renewable packaging solutions. The studies will involve experimental work as well as calculations and modelling of the barrier performance. The research focus of the

Structure-properties relationship of covalently crosslinked cellulose networks

In this work, the structure-property relationship of covalently crosslinked cellulose networks is studied by utilizing   surface modified cellulose nanofibrils and polymer links of defined structure and molecular weight. The effect of  molecular weight, chemical functionality and concentration on specific surface area, swelling, and mechanical properties of the hydrogel networks will be investigated.

BIOdegradable vegan networks from REcycled agro-food waste as sustainable single-use abSORBents (BioRESorb)

The objective is to develop biodegradable absorbents containing nonwoven fiber networks from agro-food biomass waste. The material's structure-absorption relationship will be investigated and designed to make a fully bio-based absorbent core encapsulated in a natural nonwoven fabric. The raw materials will also be combined with other natural polymers to provide additional functionality (antimicrobial or binding

Structure-property relationships in lignin-based porous carbon materials for water purification

Good water quality is essential to human health, social and economic development, as well as the ecosystem. Industrialization and urbanization, together with the explosive population growth, have caused a great challenge for maintaining safe and clean water resources. Among many strategic and research activities for water protection, a direct approach is to develop biobased porous

Cellulose-based organic solar cells via spray deposition

In this project, we use spray deposition to fabricate cellulose-based, flexible organic solar cells. We use TEMPO-cellulose nanofibrils (TEMPO-CNF) as sustainable substrate material, flexible silver- or copper-nanowires (AgNW-/CuNW) as electrode material, conductive poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) as electron blocking layer, and a mixture of poly(3 hexylthiophene) (P3HT) and [6,6]-phenyl C61 butyric acid methylester (PCBM) as

Upgrading recycled thermoplastics using cellulose oxalate for a more sustainable future 

The absolute majority of plastic used today are fossil-based thermoplastics such as polypropylene and polyethylene. To an extent these plastics are recycled through mechanical recycling but the recycled plastic is mainly used for low-end, low quality products. This is due to decreased mechanical properties and due to that the recycled plastic often obtains a black

Characterization of paperboard for creasing and folding

To form a package with desired properties, paperboard is creased and folded. Creasing creates delamination cracks which during folding cause the plies to buckle and form a permanent corner. The delamination cracks facilitate folding but reduce the load-bearing capacity of the packaging. The processes must therefore be controlled. The result is affected both by the
