Functionalization of porous materials in terms of optical, chemical and mechanical properties is achieved by applying fully wood-based layers materials. In this project, the refraction index, extinction coefficient and water adhesion properties of cellulose thin films combined with sobrerol methacrylate colloids are investigated together with their topography and morphology. Cellulose nanofibrils (CNF) are a hydrophilic material, and form networks during the drying with specific refraction index, extinction coefficient. Applying additional colloids, their optical properties and water-contact angle can be tuned. Hence, in order to produce water-resistant thin film, a combination of CNF and colloids is a perfect candidate.
