【 摘 要 】

Nanofibers have been used with increasing success for drug delivery and various biomedical engineering applications. The mixture of 13% pullulan-aloe vera can be pumped with a minor effects on the flow behavior. The fiber is then characterized by SEM, shear viscosity, storage and loss moduli. The oscillatory shear data is employed. The mixture has a complex rheological properties that includes extreme shear-thinning as well as viscoelastic properties and yield stress. The rheology of the pullulan-aloe vera nanofber was characterized, the measurement method may influence the results, it is unclear how the behavior near walls influence the measurement method, Parallel-plate rheometer is used to measure rheological properties. The data and rheological parameters should facilitate a better understanding of the process-ability characteristics of the mixture. The cross model provides a simple way of quantifying the viscosity/shear rate profile for a shear thinning mixture. SEM images are carried out.
