Nanofiber Characterization with Electron Microscopy

Extruded fibers used for nonwoven textiles are found in many consumer products, including filters, wipes, automotive components, upholstery, sports apparel, roofing materials, bedding, fiberglass boats, surgical gowns, and diapers. Fabrics, filtration, medical scaffolds, fuel cells, insulation and other applications now include nanofibers for improved product performance.
Whether nanofibers are manufactured using melt blown, spunbond, forcespinning, electrospinning or other technology, imaging and analyses require greater resolution than traditional fibers. Instead of an optical microscope, a scanning electron microscope (SEM) is needed to measure nanofiber diameter and pore distributions.
Benefits of the Phenom SEM for Fiber Analysis
The SEM combines high contrast imaging, depth of field and spatial resolution to examine and characterize features at the nanofiber scale. Nanofiber images are quickly acquired thanks to the accessibility and intuitive interface of the Phenom SEM.
FiberMetric Capability for Fiber Analysis
The Phenom desktop scanning electron microscope uses FiberMetric, proprietary fiber measurement software, which measures fiber diameter, orientation and pore sizes.
- Fast fiber analysis
- Statistically significant data
Using the integrated motorized XY stage, data acquisition and analysis can easily be automated. This software/hardware combination allows for hundreds of images to be acquired and analyzed, accumulating in tens of thousands of measurements, providing statistically significant data.
