BIOSUPHYOL Completed

Development of bio-based and PFAS-free coatings

Development of non-toxic, bio-based (>80%) alternatives to PFAS to provide superhydrophobicity and oleophobicity to paper and textile packaging.

Paper-based packaging and textile applications will be the primary targets as they are the most likely to release PFAS into the environment, though the technology could be adapted for other applications. To achieve the targeted performance level, the coating will combine low surface energy bio-based compounds (fatty acids, proteins, etc.) with optimal micrometric roughness provided by cellulose microfibers. For applications requiring mechanical and chemical durability (e.g., high resistance to abrasion and/or washing), an additional cross-linking step will be implemented. The resulting materials will not only be safe and compliant with upcoming regulations, but they will also be more sustainable due to improved recyclability and reuse potential thanks to the absence of toxic compounds.
