Main Methods:
- Utilized a semiautomatic sheet former for nanopaper preparation.
- Produced cellulose nanopaper and cellulose/inorganic hybrid nanopaper.
- Conducted uniaxial tensile tests and optical transparency measurements.
Main Results:
- Successfully prepared large (200 mm diameter), flat, smooth, and optically transparent cellulose nanopaper sheets.
- Achieved a preparation time of 1 hour for 60 μm thick nanopaper.
- Demonstrated high tensile strength in the nanopaper sheets, indicating well-dispersed nanofibrils.
- Showcased the adaptability of the method for creating cellulose/inorganic hybrid nanostructured functional materials.
Conclusions:
- The developed semiautomatic sheet forming method offers a rapid and scalable approach for producing high-quality cellulose nanopaper.
