Incorporation of Carbon Nanotubes into UV-Polymerizable Formulations: Part 1
The most common allotropic form of the element Carbon is graphite. This inorganic polymeric material is found in all pencils, where it mistakenly is called “lead.” Despite being a non-metal, it also is an excellent conductor of electricity and is used as an electrode in laboratory and industrial settings. The usefulness of graphite in pencils comes from the fact that its … [Read more...] about Incorporation of Carbon Nanotubes into UV-Polymerizable Formulations: Part 1
