| Outline of Final Research Achievements |
For the numerical analysis of spinning behavior near the nozzle in laser heated electrospinning (LES) of poly (ethylene terephthalate) (PET), the simulation results were relatively similar to the values obtained from the actual measurements. With the increase in the laser power, the distribution of birefringence of fibers in the PET web showed a bimodal distribution at low and high values.
The LES process of the cellulose nanofiber (CeNF)/high-density polyethylene (HDPE) fibers were stable in a wide range conditions and promoted to get thinner compared to the neat HDPE fibers. The neat PP fiber prepared by LES showed a specific crystal structure. In addition, the elecrospun CeNF/PP fiber showed high intimal modulus compared to the electrospun neat PP fibers, i.e. the mechanical property was improved.
