Superhydrophobic modification of cellulose film through light curing polyfluoro resin in situ

Cellulose-based film has a poor water vapor barrier property, which limits its applications in food packaging. The hydrophobic modification of cellulose materials has attracted increasing interests. In this work, UV curable polyfluoro resin was incorporated into the cellulose matrix for superhydrophobic modification of the cellulose matrix. Results showed that the loaded polyfluoro resin had an obvious influence on the composites’ microstructure, the thermal stability of the composites changed slightly with the incorporation of polyfluoro resin, and the transmittance of the composites containing the resin with high content of 14.68% could be kept to 50% at 550 nm wavelength. Furthermore, the surface properties of the composites could be changed from hydrophobic to superhydrophobic by increasing the polyfluoro resin content. Moreover, UV-initiated polymerization was used to modify the cellulose matrix, the process was green and facile, which showing potential for cellulose matrix modification.
