The file contains CEM images of a 3D resin for dentistry (amorphous). Can you determine by structure (there are impurities) and elements (Na, Cl, Al - impurities) what kind of polymer and its applicability? What works have such images? What works describe the relationship between structure and elemental composition and the applicability of such materials? Thank you!
As per the images, that can be almost any hard resin. Impurities are mainly mechanical inclusions (except for NaCl), which are also typical for this material.
The information I see on these images: brittle chips with no soft whiskers (that means the material is fully polymerized and hard under given conditions), and some inner structure (globules of 300-400nm).
I would recommend getting ATR-IR or Raman spectra for the material and checking the database for a match. PXRD may also help, but that's more expensive, longer and not really suites the task.
