The project is on preparing novel types of polysaccharide based materials with new functionalities. The focus is on building materials with unique structures, understanding the on structure-property relationship, and then modifying the structures in a controlled way so that the materials can be utilized in a specific application.

Holmen is a major Swedish producer of paper and board products. Most of these products are based on softwood fibres. During converting of the products, they are plastically deformed in folding, creasing or embossing operations. This deformation occurs both in a macro and microscale. It is therefore important to understand the influence of the raw

The project is of explorative nature and aims on mapping the destructive nature of cavitation on cellulose fibres. Neither cavitation nor the dispersion of cellulose fibres in its constituents (cellulose fibrils for dissolving pulp fibres) is fully understood. The project objective is to guide whether cavitation is a mean for efficient and dedicated fibrillation at

The fundamental facet of this project is to design and fabricate functional composite filaments based on CNF and polymers. The aim is to prepare filaments with superior mechanical properties and/or advanced functions. In this project, we are going to control the interaction between individual CNFs during flow assisted assembly using different heterofunctional polymers. The project is

Modern produktutveckling är till allt större del virtuell vilket innebär att datormodeller används för att förutspå en förpacknings beteende innan den existerar fysiskt. Fördelen med att använda datormodeller är att produktutvecklarna kan pröva nya ideer och koncept virtuellt utan att tillverka dyra fysiska verktyg samt att ledtiden från ide till produkt kan kortas avsevärt. Vidare

Den globala efterfrågan på textilfibrer ökar kraftigt, samtidigt som världens bomullsproduktion har stagnerat bland annat p.g.a. konkurrens om den odlingsbara arealen. Bomullsproduktion medför dessutom en stor belastning på miljön, och det finns starka incitament att ersätta både bomull, och den oljebaserade polyesterfibern, med ett mera miljövänligt och långsiktigt hållbart alternativ såsom cellulosa från trä. Idén

The project is a post-doc project within WWSC 2.0 The engineering aim brought forward in the project is to produce composities by using chemically modified fibres and nanocellulose and use these as reinforcing-structural elements in a polymer matrix. The resulting composites material must be manufactured with conventional, possible slightly modified, polymer processing techniques in order

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

The project involves the development of new experimental methods to characterize deformation processes in fiber-based materials, in particular paperboard. The experiments are to be performed on several scales, from micro to macro, and aim to increase understanding of the mechanisms that control the mechanical properties and behaviour of the material. Experimental devices that can be

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.
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.
