procedure for sample preparation of polymer nanocomposite coatings for electron microscopy

摘要

the invention is in the field of electronic control line by microscopy and quality of plastic nanokompozitnih coatings. solves the problem of sample preparation for the analysis of very thin plastic coating whose thickness is over 0.5 um, which are involved in a very small particle size diameter of from 10 nm to 100 nm, the so-called nanoparticles, with the method of line electronic by microscopy.in the process of carrying the conductive metal foil, which together with the adhesive stop in liquid nitrogen. thicker coatings are distinguished from foil, fragile break and analyze. coatings of less than 3 um does not separate from the film, but only brittle break. in both cases, we use the carrier, which allows the pressure of the coating both sides of fracture surface and vertically.
