A senior scientist at the VTT Technical Research Centre of Finland developed new hybrid materials with enhanced diffusion barriers, for use in the production and modification of thin-film composites.
Juha Nikkola’s doctoral research project involved studying and developing flexible composites using various coating techniques and examining the impact of the surface layer on the permeability and anti-fouling properties of thin-film compounds. The assignment focused on atmospheric plasma deposition, atomic layer deposition and sol-gel deposition techniques.
The project resulted in a range of materials that decreases bacterial adhesion to film surfaces. The materials have an application in coatings for cardboard packaging, among other types of packaging, where it can assist in delaying the spoilage of food.
