Production of mesoscopically patterned cellulose film.
Honeycomb and stripe patterned films were prepared from cellulose triacetate (CTA)/chloroform solution, as a result of the self-organization of the polymer during evaporation of the solvent. The honeycomb patterned CTA films were prepared by two methods, a direct pattern formation method and a transcription method. The latter method gave a well-organized microporous honeycomb pattern. Both types of patterned CTA films were saponified to yield the corresponding patterned cellulose films.
