钠基蒙脱土改性明胶/PEG复合纺丝液的制备及流变性研究

he gelatin/PEG composite spinning solutions with different amounts of MMT have been prepared, and their rheological behaviors have been investigated. The results indicate that the composite spinning solutions behave as bulging plastic fluid. The viscosity of the gelatin/PEG-MMT solution decreases with increasing temperature, and meanwhile, it increases first and then decreases with the increase of MMT content. This study shows that proper amount of MMT disperses well in gelatin/PEG solution and hence increases the viscosity of the solutions as a crosslinker between polymer chains. However, excess MMT may cause the aggregation of polymers. TEM observation further confirms the conclusion above.
