Engineering Morphology and Porosity of Nanofibrous Mats through Collector Adjustment

In this study, the effect of metal mesh size on the structural properties of electrospun polycaprolactone (PCL) nanofibrous mats was investigated. Various metal meshes with different pore sizes were used as collectors in the electrospinning process to control the fiber morphology and porosity of the resulting nanofibrous mat. Scanning electron microscopy (SEM) was employed to assess fiber diameter, distribution, and porosity in relation to mesh size. The results showed that smaller mesh sizes lead to higher surface porosity between the mesh wires and a finer fiber diameter. The findings provide insight into optimizing electrospinning parameters and collector design for producing nanofibrous mats with tailored properties for a variety of industrial applications.
