A Chinese research team has now developed a sustainable solution: transparent coatings based on zwitterionic cellulose nanofibres (ZCNF). Reading tip: Bio-based coatingsThe EC Tech Report “Bio-based Coatings” is a hand-picked compilation of all the key aspects concerning bio-based coatings, offering the latest technical developments. Long-term performance in marine environmentsBoth laboratory studies and marine field trials confirmed the effectiveness of ZCNF coatings. The study demonstrates that zwitterionic, bio-based coatings represent a sustainable alternative for protecting marine optical devices – without the use of environmentally harmful biocides.
