 The study explores the use of nanofibrillated cellulose-based composite films obtained from cotton linters oxidized with Tempo, NAB-R to NAC-LO system, filled with CAC-03 and or ALOH3, and plasticized with glycols to improve the mechanical, optical, and sorption properties of paper. The results show that the paper coating with these films enhances the mechanical properties while decreasing sorption properties without significant changes in optical properties compared to the initial papers.
