Materials Chemistry of Cellulose

The distinct emphasis of the group led by Prof. Eero Kontturi is set on interfacial phenomena: one of the main lines of research involves observing and manipulating cellulosic materials in confined 2D space by using a surface science approach. Basically, this means performing research on cellulose-based entities on a very flat surface. The impetus for such research is provided by the vast diversity of functional materials that can be manufactured from 2D constructions, such as sensors and optoelectronic devices.

Research themes:

1. Plant cell wall polymers in 2D

Focus is on building morphologically distinct 2-dimensional structures from well-defined cell wall components, such as cellulose nanocrystals or amorphous polysaccharides. The structures can be positioned on a flat, smooth surface to provide means for observing fundamental interactions between plant cell components when confined in 2D space. The results can also be applied to utilizing interfacial phenomena in more realistic materials like plant-based fibres where, for example, adsorbing elements are used to perform certain tasks on the fibre surface.

2. Cellulose-inorganic hybrids: new family of thin films for energy materials

This effort centres around building thin films from cellulose-based and inorganic materials. Electrical and thermal conductivity as well as optical properties of the films are under particular scrutiny and the application targets are therefore set in energy materials, such as thermoelectric devices. Our group’s wide-ranging knowledge on manufacturing various kinds of cellulose and cellulose derivative films are utilized in tuning the desired film properties. This is a consortium with VTT High Performance Fibre Products and an integral collaboration with Inorganic Chemistry group at Aalto.

3. Towards realistic, green, and low-cost production of cellulose nanocrystals

This project aims <strong>at overcoming or circumventing the bottlenecks in cellulose nanocrystal production. Instead of the conventional liquid acid / solid fibre system, a gas/solid system is applied in a custom-built reactor. Various ways of dispersing the nanocrystals from a hydrolyzed fibre matrix are at the centre of this effort. The concept report on the industrial feasibility of the gaseous HCl hydrolysis method can be found here.
