A high-resolution C1s ESCA spectrum showing hydrocarbon (C-C, C-H) bonding at the 284.9 eV peak, hydroxyl carbon (C-O-H) bonding at the 286.7 eV peak, ether carbon (O-C-O) bonding at the 288.4 eV peak, and ester carbon (O-C = O) bondings at the 289.6 eV peak. No E-beam (upper left), inner (upper middle), and outer (upper right) surface of 2 MeV - 0.24 mA - 120 kGy irradiated CM. A high-resolution O1s ESCA spectrum showing hydroxyl oxygen (−C-O-H), ether oxygens (−C-O-C-), and ester oxygen (−COO). No E-beam (lower left), inner (lower middle) and outer (lower right) surface of 2 MeV - 0.24 mA - 120 kGy irradiated CM [confirmed permission from reference journal 11]
