Fabrication and characterization of regenerated cellulose /TiO_2 nanocomposite hybrid fibers

摘要

Nanocomposite fibers are one of the most fascinating materials with broad applications. In the present work, nanocomposite fibers were prepared by a low-cost, simple, and "green" process. The nanocomposite of regenerated cellulose/TiO_2 was realized by combining the functional oxide material TiO_2 with the regenerating electrospun cellulose acetate fibers. The structural features were characterized by scan electron microcopy, transmission electron microscopy and infrared spectrum. The compositing mechanism was proposed. The surface functionalized hydroxyl by the regenerating process plays an important role for the formation of hybrid material.
