Light-Based Method Creates 2D Polymer, Expedites Quest for New 2D Materials

Facebook X LinkedIn Email
LINKÖPING, Sweden, June 16, 2021 — A method that uses light to manufacture 2D polymers that have the thickness of a single molecule could create a path for the development of ultrathin, functional 2D materials with highly defined and regular crystalline structures. The new method was developed by an international team of researchers from Linköping University, the Technical University of Munich (TUM), the Deutsches Museum, and other institutions. Using an on-surface photopolymerization process, the team developed and tested a way to manufacture a 0.5-nm-thick, 2D polymer consisting of several hundred thousand...Read full article

    Glossary
    polymerization
    Process of synthesizing long molecular chain materials (polymers) by reaction of many small molecules (usually thousands) called monomers.
    photopolymerization
    A process in which a mixture of one or more monomers, plus a catalyst, polymerize under exposure to light radiation. Photopolymerization permits a hologram to be exposed, fixed and reconstructed in about one-half second.
    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    filter
    1. With respect to radiation, a device used to attenuate particular wavelengths or frequencies while passing others with relatively no change. 2. See digital filter.
