Özet
Porosity is a critical microstructural parameter that directly affects the physical, mechanical, and functional properties of fibrous materials. In this study, nanofiber filter membranes were produced from mixed solutions of Polyamide 6 (PA6) and Cellulose acetate (CA) polymers at different ratios (0/100, 50/50, 100/0) using the electrospinning method. The porosity of the produced membranes was first measured experimentally. Then, it was calculated from Scanning Electron Microscopy (SEM) images using a novel segmentation method consisting of a combination of different image processing techniques. The results obtained with this method were compared with the results obtained by the experimental method, and the method consistent with the experimental results was proposed for porosity measurement. Overall, the findings show that the proposed image processing pipeline offers a reproducible and quantitative analysis approach for area-based porosity calculation, individual pore separation, and morphological characterization in fibrous microstructures.
