Ferromagnetic Membrane Pore Opening Control and Laser Pattern Analysis

The electrospinning technique has been employed in the fabrication of various applications, such as sensors, filtration equipment, drug dispensers, and others. Currently, manufacturing processes have advanced to enhance precision in membrane orientation and morphology, thereby enabling control over nanofiber diameter and alignment. However, once fabrication is complete, this morphology becomes fixed. This study presents an analysis of modifying pore openings in ferromagnetic membranes under a magnetic field. The analysis is supported by specialized equipment designed for analyzing laser-projected patterns. The observed behavior shows a clear dependence on the voltage applied to the electromagnet generating the magnetic field. It is proposed that future advancements will improve control, potentially affecting the flow of both light particles and liquids.
