Composite fibers based on cellulose and polyacrylonitrile copolymers

详细

Composite fibers were obtained from highly concentrated solutions of cellulose and polyacrylonitrile (PAN) copolymers in N-methylmorpholine-N-oxide (MMO). The processes of co-dissolving cellulose and PAN in MMO and the rheological properties of the resulting composite solutions were examined. It was shown that introduction of PAN into the cellulose matrix affects the structurization processes. Specifically, an increase of the PAN content in the cellulose matrix affects the thermal behavior and mechanical properties of the composite fibers.
