Our research contribute to a sustainable development. By using renewable in/organic (nano)materials (such as cellulose, lignin, polysaccharides, proteins, minerals) and bio-based/derived polymers (such as PVA, PLA, PUR, waxes, fatty acids) we strive to develop the next generation of smart (sensing, secure, thermo-regulating) and multi/functional (protective, bioactive, barrier) surfaces (textiles, films, foils, paper, membranes) for wearable/flexible electronics, energy storage/harvesting devices, active and smart (safety, security) packaging, and selectively-adsorptive membranes/filters for water purification.
