Abstract

Marine optical devices face significant biofouling challenges, which compromise their transparency and disrupt their functionality. Existing coatings, typically relying on toxic biocides or dynamic surfaces, harm the marine environment and fail to meet the signal stability required for high-performance equipment. In this study, we introduce a fully bio-based approach to transparent antifouling coatings by developing zwitterionic cellulose nanofibers (ZCNF) modified with lysine, arginine, and histidine. Notably, this innovative modification exhibits enhanced hydrophilicity and antifouling properties compared to unmodified cellulose nanofibers, while also forming a stable antifouling surface, overcoming the key limitations of conventional materials. Laboratory and marine field tests demonstrate the remarkable long-term performance of ZCNF coatings, achieving up to 90 % antifouling efficiency in controlled environments and 80 % in real-world conditions after 150 days. This work provides a sustainable alternative for marine optical coatings, advancing the application of bio-based nanomaterials to address real-world marine challenges.

期刊介绍： The aim of this international journal is to analyse and publicise the progress and current state of knowledge in the field of organic coatings and related materials. The Editors and the Editorial Board members will solicit both review and research papers from academic and industrial scientists who are actively engaged in research and development or, in the case of review papers, have extensive experience in the subject to be reviewed. Unsolicited manuscripts will be accepted if they meet the journal''s requirements. The journal publishes papers dealing with such subjects as: • Chemical, physical and technological properties of organic coatings and related materials • Problems and methods of preparation, manufacture and application of these materials • Performance, testing and analysis.
