Polymer Science Application Note

We are very excited to announce the posting of a new application note to the Delong America Website. Dr. David C. Martin has taken the time to discuss how the LVEM5 has helped him in many areas of his polymer research. The application note is now posted in the Library Section of the website.


The 5 kV operating voltage significantly increases the TEM image contrast, making it possible to minimize or avoid altogether the use of heavy metal stains that are usually a necessary evil in polymer transmission electron microscopy. The LVEM5 has proven to be particularly useful for the high contrast imaging of a wide variety of polymers, organic molecular thin films, and biological materials. We have obtained images on a variety of systems including polyethylene single crystals, pentacene and TIPS-pentacene thin films, block copolymers, and poly(3,4-ethylene dioxythiophene). We have also found it useful for imaging single dendrimer molecules, as well as a variety of inorganic nanoparticles.
