Hi guys
I have prepared a bilayer electrospune mat with different composition based on PVDF polymer and I wanna break it for EDX best image and result. However I couldn't make it brittle by liquid nitrogen and it disintegrated. what should I do?
you can get cross-section of sample using microtome machine
As Kishore Kumar Sriramoju said, cross sections may help. You may need to embed the sample first, but that can lead to other problems. The sample may be harder to see.
What size are your fibers and what you want to measure by EDS?
If they are sub-micron, you will likely not get a clean analysis. Most EDS system report results based on the assumption that the sample is a homogeneous, dense, flat material. As you violate those assumptions, the results get worse.
If all you want to show is C and F, then you might be okay with looking at the mat of fibers. However, you may want to put the mat down over something like a Si substrate. If you see Si in your spectrum, then you know you are penetrating through. If the mat was on a C substrate or tape, you wouldn't know if the C was from your sample or the substrate.
