NanoTextSurf - NanoTextured Surfaces for textiles, paper and plastics
The NanoTextSurf project aims at creating unique material properties and next generation products with surface treatments and coatings containing nanocelluloses. Nanocelluloses are plant or usually wood-based nanomaterials that have particles sizes in nanometer scale.
The nanotextured surfaces are created on textile, paper and plastic webs with various application techniques. After the treatment, the web has properties such as antifouling, pollutant capturing, improved strength, right tribological properties, enhanced durability in grinding and barrier against adhesive glue. Nanocellulose can directly provide the desired property or act as a binder for another agent on the surface. Stability of the nanocellulose dispersions or foams in the application is an example of typical challenges.
The suitability of these materials is demonstrated for filtering membranes, textile workwears, low-friction materials, and surface finishing applications.
The project also focuses on developing manufacturing technologies of these surface treatments. From this perspective, the production of the novel nanotextured surfaces offers a beneficial environment to optimize and upgrade the equipment installed in the R&D pilot lines. An important part of the work is to optimize the coating dispersions or printing pastes.
