概要（目的・用途・実施内容）/ Abstract (Aim, Use Applications and Contents)
We fabricated a nanofiber by electrospinning and have treated it with a chemical solution for surface modification. to ensure the success of this surface modification, we performed SEM analysis to verify the surface morphology of the nanofiber after modification compared to the nanofiber before. We confirmed that the surface of nanofiber became rough after treatment with the solution
実験 / Experimental
First the nanofiber was fabricated by electrospinning. Then it was etched. Finaly, the effect of etching was observed by comparing the structure before and after by SEM analysis ( JSM-7500FA).
結果と考察 / Results and Discussion
Figures 1 and 2 illustrate the changes in the nanofiber surface. Initially, the surface was smooth before the etching process. Post-etching, it became rough, confirming the etching process's success and effectiveness. This visual evidence clearly demonstrates the intended surface modification achieved through etching.
