Materials research at VTT is clearly bound to industrial needs


Nanomodified hybrid polymers
Nanomodified Hybrid Polymers industries

  • Aim is to develop novel ways to control the electrical characteristics of polymer-based materials:

    • to improvethe thermal stability of electromechanical materials (piezoelectric charge endures at high temperatures)

    • to reduce the dielectric constant of materials (nano- and microporous in hybrid polymers)

    • to improve insulation properties against high voltage

Nanocomposite Polymer Capacitor Film:

Polyaniline 1-3 wt-% increases AC- and LI- breakdown strength of capacitor grade polypropylene thick films (t=150 µm) while increasing the permittivity by 10%. Energy of the capacitor  εr , U2


Adhesion proteins for highly defined surface modifications

Microbial adhesion proteins self-assemble at interfaces and can be used for producing one-molecule thick highly ordered surface layers.

10 nm

Atomic Force Microscope (AFM) image of a one-molecule thick surface assembled layer of protein. The dimension of the repeating unit is 6 nm.

Genetic engineering can be used to modify and functionalize the adhesion protein. AFM image shows individual molecules of a one-molecule thick layer of avidin-protein fixed to the adhesion protein.

Functional composites from wood based materials and biopolymers
Functional composites from wood based materials and biopolymers

  • Combining of wood and wood-based fibres with different materials

    • plastics

    • concrete

    • mortar

    • ceramics

  • Innovative hybrid composites with intelligent fibre-based functionality

    • monitoring, indicating, detecting, actuating

    • porosity gradients

    • multi-layered, low density materials with adequate mechanical properties

    • improved acoustic properties

    • improved fire and thermal resistance

  • Justifications

    • cladding materials with multi-layer structures

    • interior decorative films or boards with fire resistance and acoustic properites

    • mobile elements with good sound absorbing properties

    • flooring materials


Functional thin coatings for wood and fibre based materials
Functional thin coatings for wood and fibre-based materials biopolymers

  • GOALS

  • Scratch resistance, wear resistance: to increase the utility value and durability of wood and fibre based products by organic-inorganic hybrid coatings

  • Surface modification: to modify surface properties in order to tailor printability (water and oil absorption) and soil repellancy properties of fibre based products

  • Barrier properties: to produce barrier properties such as controlled moisture behaviour, gas permeability and UV-shield

  • Formability: to develop elastic, durable binding solutions for mouldable fibre based products such as cardboards

  • Application: to preliminarily clarify cost effective application methods for promising coatings and treatments

Surface free energy affects e.g. to soil repellancy, cleanability and printability of surfaces. Surface energy can be affected by chemical structure and topography of surface.

Adhesion of nanostructured hybrid sol-gel coatings to organic matrix is greatly increased by covalent bonding

Smart Filter - adaptable pore size

  • Fiber filters coated by PNIPA polymer

  • At temperatures <TLCST. The volume of polymer is expanded state ( the polymer binds water molecules). Fibers are "thick" and pores are "small". The system is highly hydrophilic.

  • At temperature >TLCST , the polymer rejects water molecules out and the volume of the polymer decreases dramatically. Now the fibers are "thin" and pores are "large". The system is hydrophobic.

    Now we have a filter with adjustable pore size! The washing can take place easily.
