Question

How would you prepare a sample of solvent-etched polymer for introduction into a Scanning Electron Microscope? Discuss the instrument parameters you would use to image this sample and why you would require these parameters?

Answer 1

* There are many ways to etch a polymer by using chemical etching, a strong acid or another corroding chemical will used to prepare the sample of solvent - etched polymer.

The etched can either be a gaseous form or in liquid form.

By the help of most number of chemical corroding we prepare it.

For chemical etching two type of fuel pellets are required to prepare

By thermal and electrolyte inducing etching we also prepare it

one containing pure uranium nitrite and the other a solution of uranium
