Abstract

A new kind of a fibrous material is produced by controlled self-rolling of patterned thin poly(4-vinyl)pyridine films in acidic water. Self-rolling is induced by unequal swelling of the top and the bottom layers of the films in the solvent. Rolling starts from parallel scratches in the film and results in twin-scroll fibers. The fibers are stabilized by staining with CuCl2 salt and freeze-dried. The output of the fiber material production is of the order of 1 cm3 from approximately 50 cm2 of the patterned polymer film. The approach opens new broad opportunities for creation of smart fibrous materials via loading the fibers with functional micro- and nanoparticles.
