Abstract

Developing nanofiber mats with unique three-dimensional morphology (3D) are of great interest to biomedical engineers working on nanotechnology. Herein, we report cellulose acetate nanofiber mat with honeycomb-like surface structure for the very first time. Cellulose acetate nanofiber mats (CANFs) were prepared via a simple electrospinning technique. A new and straightforward oil spray method was developed to create the honeycomb like structure on the nanofiber mats. The patterned structure of the prepared nanofiber mat (hs-CANFs) was investigated. The diameter of the honeycombs created on the nanofiber mat ranged from 150µm to 450µm. XRD data revealed the amorphous nature of the prepared CANFs and hs-CANFs. The structure of the nanofiber mat was also studied by FT-IR analysis.
