Fiber orientation on 3D structured collectors for electrospinning

Abstract Electrospinning, a standard technique for producing nonwoven fabrics, is widely used in the biomedical field. Due to local electric fields, fiber deposition influenced by 3D surface structure of metallic collectors. For complex shaped structures, predicting and orientation fibers remains challenging. Investigations on well-defined structures permit more detailed insight. In this study, metal blocks with round, slit square holes various sizes depths were fabricated covered thin layer polymer fibers. The arrangement was investigated different microscopic methods. Analysis results showed less round well-bridged aligned gaps which than four times wide as deep. Experimental confirmed theoretical predictions. Considering these findings, further work can be addressed specific collector design attain targeted deposition.
