## Description

- description: "   The damage mechanism and exposure tolerance of epoxy resins to
    fast electrons remain unclear. We quantitatively investigated the effects of electron
    irradiation on a common epoxy resin by dose-dependent electron energy loss spectroscopy
    (EELS). The results show that sp3 states of nitrogen, oxygen, and their adjacent
    carbon atoms were converted to sp2 states, forming imine (C=N) and carbonyl (C=O)
    as the total electron dose increased. The sp3 to sp2 conversion mechanism was
    proposed. The epoxy resin was very sensitive to fast electrons and the original
    electronic states were maintained up to a total dose of ~10^3 e− nm−2 at a low
    temperature of 103 K. Dose-dependent electron diffraction (ED) revealed that the
    intra- and intermolecular geometries changed below and around the total dose of
    ~10^3 e− nm−2."
