Abstract
Effects of unmagnetized and Magnetically Confined Laser-Induced Cu plasma Ions (MCLICPI) on surface, optical, wetting, electrical and mechanical properties of PMMA have been explored by SEM, UV–visible spectroscopy, contact angle measurements, four probe method and hardness tester respectively. The enhancement in maximum fluence from 3.7 × 1016 to 3. 8 × 1017 ions/cm2 and energy from 5.1 keV to 6.7 keV of MCLICPI are attributed to magnetic confinement and Joule’s heating effect. SEM analysis reveals the formation of beaded structures, pits, dendrites and flakes on PMMA. Growth of CuO and Cu2O phases and variations in hydrophilicity of PMMA are observed after ion irradiation. Significant increase in electrical conductivity and hardness of MCLICPI irradiated PMMA is observed. The ions range, electronic and nuclear stopping are 122 Å, 2.7 eV/Å, 57.5 eV/Å for unmagnetized and 146 Å, 3.1 eV/Å, 61.7 eV/Å for MCLICPI respectively.
