In this research, freeze drying was utilised to remove excess water from wet CNF and CNF-PF composite films, which sped up the processing time and made the films wrinkle-free. The nanocomposite was manufactured by heating the freeze-dried sheets. Primary physical and mechanical factors were evaluated in addition to the morphology. Discontinuous patches, possibly voids generated by low-temperature drying, can be seen in both CNF and CNF-PF complex films. Both films show these gaps. The films are both supple and robust since the adding of PF has a negligible impact on the mechanical strength of the material. The mechanical asset of a film is often diminished after being freeze dried as opposed to oven dried. Freeze-drying CNF and CNF-based nanocomposites can be an efficient method of preparation when time is of the essence.
