Group's research areas are:

  1. Bio-based carbon material:
    Wood-derived polymers and other biopolymers are subjected to tailored pyrolysis protocols to produce bio-based carbon material. The main applications targeted are carbon fibers, carbon material for energy harvesting and storage, and carbon catalysts for chemical reactions.
  2. Rheological behavior of biopolymer solutions and suspensions:
    Traditional and novel solvent systems are explored to dissolve various biopolymers and non-polymeric constituents. The solutions or suspensions are characterized by a comprehensive set of rheological tools (shear, capillary and extensional rheometers).
  3. Biopolymer-based fibers and yarns for functionalized textiles:
    Cellulosic and other biopolymeric fibers are modified following the twelve principles of green chemistry. Functionalized textiles are developed together with Aalto University’s textile engineers and designers.

The team led by Prof. Michael Hummel studies various biosynthesized polymers such as lignocellulose, non-plant based carbohydrates, and polypeptides using a comprehensive set of analytical tools and processing equipment.

Seven-figure grant for researcher producing carbon fibre from wood

Michael Hummel, the recipient of the much sought-after ERC Starting Grant, knows that there is a great need for more affordable carbon fibre.

The ERC is funding ground-breaking, cutting edge research. What is needed for opening up new paths?

‘Cooperations that allow for a multi-disciplinary approach are very central. In addition to experts in wood chemistry and forest products technology, we have various specialists in engineering and other sciences’, says Michael Hummel.
