There are included two folders in the source: 1. Raw pictures of the Scanning Electronic Microscope (SEM) analysis of the composite's surface 2. Spectral analysis of the composite's surface with the energy dispersive X-ray spectroscopy (EDS) and retractable Backscattered Electron (BSE) detector of the microscope TESCAN VEGA SBU.


Steps to reproduce

Research data on surface elemental mapping and spectrometry. The images of composite surface were obtained by a scanning electron microscope (SEM) VEGA 3 SBU (TESCAN) with a Secondary Electrons mode (SE) for the inspection of the topography surfaces and energy dispersive X-ray spectroscopy (EDS) with a retractable Backscattered Electron (BSE) detector for the information on the sample’s composition. SEM analysis has been done on the exterior and interior surfaces of the flax straw particles with a size of 6.5 mm × 1 mm. The analysis was performed in the high vacuum pressurized chamber (<1×10-2 Pa). The 30 kV electron beam with the resolution of 3.0 nm (arbitrary unit, defined by Vega3 TESCAN) [according to Instruction for use VEGA 3 SBU, TESCAN] and the working distance at a range between 14.87 mm till 18.98 mm were used. Incident probe current, contrast and brightness levels were set to allow the obtaining a colorless surface mapping (SE images) and dispersive spectroscopy (BSE images) with a good quality for further processing. Each separate microscope image contains microscope mode information including detector mode, working distance in mm, view field in mm, scale, and zoom magnification.
