Functional materials

Competence
More than 50 specialists at VTT use their knowledge of and passion for the development of innovative material solutions with new functionality. VTT’s material development research efforts rely on advanced experimental facilities and strong process expertise. Through its broad expertise in experimental research and by networking with first-rate international partners, VTT is able to provide new functional material solutions.

Challenges
Materials face new challenges due to the current development trends in engineering, such as the demand for high performance, a minimized ecological footprint, embedded intelligence, miniaturization of components and features, harsher operation and process environments and development of energy-efficient processes and machinery.

Solutions
VTT’s solutions for functionality are aimed at a unique combination of material properties. Materials with active functionality can respond actively to a stimulus. VTT’s research into functional materials covers:

  • Powder development and powder metallurgy
    Powder development ranges from nanoparticle synthetization and functionalization to micro-scale powder processing, modifications and characterization. Novel composite materials are developed to create new business opportunities.
  • Thermal spraying and tribology Tailored coatings for extreme conditions and other special functionalities are developed using various thermal spray-coating methods. Tribology research covers friction, wear and lubrication for a wide scale of materials with a modelling-assisted approach.
  • Functional polymers
    Functional polymer research at VTT focuses on creating added value for next-generation material solutions. This is performed by combining cumulated profound expertise in chemistry with material processing technologies.
  • Multifunctional surfaces
    Tailored surface properties via the AddSolTM coating solution. By applying sol-gel technology, several functionalities and combinations of them, such as dirt repellence, scratch-resistance, and anti-microbial and anti-ice properties, can be targeted.
  • Biomimetics
    By applying inspiration from nature when developing new advanced functional materials, novel sustainable solutions for industry can be achieved. VTT’s expertise consists of synthetic biomimetics, bio(nano)materials and various hybrid solutions of these.
  • Materials and solutions for embedded sensing
    Integrated intelligence for machines and components is developed by studying Direct Write technologies and other unique sensor methods. Energy harvesting materials and other integrated elements for self-supporting sensing systems are also targeted.
  • Cementitious materials
    Material technology comprises the study of the mechanical, chemical and physical characteristics of fresh and hardened concrete as well as assessing the microstructure in concrete. The manufacturing technology comprises the production of concrete and manufacturing of concrete products and related site practices.
  • Development of materials for emerging energy technologies
    VTT is combining its expertise in functional materials, nanomaterials and coatings as well as manufacturing techniques, e.g., roll-to-roll printing and powder metallurgy. VTT has widespread application expertise in bioenergy, nuclear energy, wind energy, oxyfuel combustion, fuel cells, solar energy, printed power sources and energy efficiency. Moreover, versatile characterization techniques are available for both ex-situ and in-situ characterization.
