Development of Highly Expandable Wrinkled Nanofiber Mat Using Metal Bundle Collector

Nanofibers are used to improve performance in various fields such as biosensors and medical scaffolds. However, when it is used closely with a biological tissue, it is difficult to properly implement the original function due to the deformation caused by the constant movement of tissue. In this study, we developed a wrinkled nanofiber mats with excellent expandability using a novel metal bundle collector. The wrinkled nanofiber mats are composed of aligned nanofiber and random nanofiber repeated at regular intervals, and can move appropriately in response to the strain as the wrinkles formed in the aligned region can be wrinkled and spread.
