“…Cellulose‐synthetic polymer blends offer the promise to produce new materials with synergistic improvements in physical, physicochemical, and functional properties. Over the last few decades, blends of cellulose with various types of synthetic polymers have been investigated widely, such as cellulose with poly(ethylene glycol),1 polyamide 66,2 poly(vinyl alcohol),3 and polyacrylonitrile 4. For the preparation of cellulose blends, natural raw cellulose and synthetic polymer were dissolved into solution individually, followed by mixing the two solutions homogeneously at a desired ratio.…”

Shape memory effect (SME) was achieved for cellulose–polyurethane (PU) blends of different compositions in wet–dry cycles, featuring that the amorphous cellulose and the PU content served as the fixing phase and the recovery phase, respectively. The dependence on the compositions of the fixity ratio and the recovery ratio was quantitatively measured by tensile tests. The morphological and thermal properties of the blends were further investigated by scanning electron microscopy and thermogravimetric analysis. The storage modulus of the blends varied reversibly in the wet–dry cycles, as determined by dynamic mechanical analysis. Furthermore, the microstructure of the blends reversibly changed correspondingly, as determined by wide‐angle X‐ray scattering diffraction and Fourier transform infrared. It was predicted that the reversible transition in different amorphous cellulose structures triggered by water led to the reversible variation in modulus as well as the wet–dry SME of the blends. © 2011 Wiley Periodicals, Inc.

New types of film materials were prepared from solutions of cellulose and its blends with poly(methy1 methacrylate), poly(viny1 acetate), poly(viny1idene chloride) and poly(acrylonitri1e) in the dimethylformamide-dinitrogen tetroxide solvent system. The films were investigated by means of differential thermal analysis, differential thermal gravimetry and thermal gravimetry.
