Wood Nanotechnology

The Wood Nanotechnology (WoodNanoTech) Group focuses on sustainable nanotechnology to transform hierarchically structured biomass, e.g. wood, into high-performing, multifunctional, nanostructured materials.
Secondary cell wall structure of nanostructured wood

We are:

  1. A group of researchers working on wood material science and functional biopolymers from nature.
  2. Part of Wood Material Science Group.

Research focus:

  1. Sustainable wood modification and nanostructural control of wood cell wall structure.
  2. High-performing wood-based biocomposites with emphasis on optical, mechanical, and dielectric properties.
  3. Biopolymers from hierarchically structured biomass for functional materials design.

Researchers Unlock a Stronger, Greener Way to Bond Wood: Finnish pulp fiber could be used to bond wood for the construction industry

Researchers at Aalto University have developed a groundbreaking wood bonding method using primarily pulp fibers from Finnish forestry. The resulting bonding interface is twice as strong as natural wood while highly resistant to water. This breakthrough could transform sustainable construction by reducing reliance on petroleum-based adhesives.
