Preparation and Characterization of Electrospun Nanofiber of Poly (Vinyl Alcohol) and Cellulose Nanocrystals
In this study Poly vinyl alcohol (PVA) and cellulose nanocrysrals (CNC) composite nanofibers were prepared by electrospinning process. To dissolve PVA, the deionized water was used due to environmental friendly of PVA. The design of experiments (DOE) was done by the Taguchi method using the Minitab...
