| 中文摘要 | in our previous work, supramolecular films composed of hydrophilic cellulose and hydrophobic polyaniline (pant) dissolved in naoh/urea aqueous solution at low temperature through rearrangement of hydrogen bonds have been constructed. to further understand the miscibility and processability of the complex solution, the dynamic rheological behaviors of the pani/cellulose complex solution were investigated, for the first time, in the present work. transmission electron microscope (tem) results demonstrated that the inclusion complexes consisted of pant and cellulose, existed in the aqueous solution, showing a good miscibility. time-temperatures superposition (tts) results indicated that the pant/cellulose solution exhibited a homogeneous system, and the complex solution was more stable than the cellulose solution in the temperature range from 5 to 25 degrees c. winter-chambon theory was proved to be capable of describing the gelation behavior of the pani/cellulose complex solution. the relaxation exponent at the gel point was calculated to be 0.74, lower than the cellulose solution, indicating strong interactions between pani and cellulose chains. relatively larger flow activation energy of the pani/cellulose solution suggested the formation and rupture of linkages in "junction zones" during the gelation processes. furthermore, pant/cellulose gels could form at elevated temperature as a result of the physical cross linking and chain entanglement, and it was a thermoirreversible process. moreover, the pant/cellulose solution remained a liquid state for a long time at the temperature range from 0 to 8 degrees c, which is important for the industry process. |
