Application of Electrospun nanofibers

Objectives
Using NMMO monohydrate as a excellent solvent for cellulose
Seeking for an optimal condition for obtaining cellulose nanofibers via Electrospinning

Different decomposition steps are
Visible.
The melt point of anhydrous
NMMO is 184oC
TGA Curves

Conclusion
Cellulose nanofibers were successfully obtained by electrospinning of 7 wt% cellulose/NMMO monohydrate solution with an average size of about 200 nm
SEM images described the morphology of the obtained product and interpreted the relationship between the morphology and the quantity of
NMMO monohydrate
Viscosity test coincided the above presumption
XRD pattern told us that the solidification of cellulose after it was dissolved in NMMO monohydrate made the crystal form of cellulose change from cellulose I to cellulose II, no relation with electrospinning
TGA data revealed that serious conglutination of cellulose nanofibers may cause a decreased degradation temperature as well as an existence of NMMO
