I guess my unknown polymer sample is polysulfone. I attached the SEM and EDS pic below.
Please take more vivid SEM micrographs containing more polymeric substance that can be easily distinguish from the background.
I am wondering that do I need to consider about Si in my unknown? My unknown sample is polymer, so it is mounted on aluminum stubs using epoxy and coated with a thin layer of Ir (~5 nm)....

They are quite similar to each other, so I want to know which one is widely used for a replacement for glass in windows.

How can I determine a good adhesion strength range for coatings on polymer surfaces, such as DLC on polymer substrates? Is there a specific threshold for adhesion strength (from T-peel tests)...

I have done sem eds analysis for Hydroxyapatite and zeolite NaP composites, but no Na and Ca elements were detected at a 500× magnification, and there should be no Ti elements, and at a 2000×...

Hello everyone, I am try to understand the differences interaction between insoluble and soluble polymers in water with metal ions and how theit charge density (of metal ions) affect the interaction.

If the pairs are similar, will it reduce the adhesion due to electric charges?

I have different polymer solutions and I hypothesize that water molecules are retained based on the water-polymer interactions, so the amount of free water is less to intercat with drug tablet....

I have an issue with SEM imaging of liposomes. When measured by DLS, they appear to be around 120 nm, but when using SEM with simple air drying, they appear much larger, around one micrometer.

I am experiencing this for the Bi2Se3 sputtering target. Initially, even if the target was 2:3 in Bi : Se, with a few sputtering runs, due to the high escaping tendency of selenium, the top layer...
