Investigation of swift heavy ion-induced mixing in metal/polymer systems

摘要

We have investigated swift heavy ion-induced mixing in Ni/Teflon and Au/Teflon systems using 120Â MeV Au ions. Our earlier studies showed that the Ni/Teflon system exhibits strong interface mixing, as determined by Rutherford backscattering spectrometry (RBS). In the present work, the Ni/Teflon system is further studied by scanning electron microscopy and Fourier transform infrared spectroscopy. Moreover, RBS studies are extended to demonstrate interface mixing in the Au/Teflon system. The observed mixing is explained on the basis of the chemical activeness (or reactivity) of the metal/polymer systems leading to a chemical reaction. The chemical reaction occurs in the hot zone around the ion path between the Ni and reactive polymer species. Thermodynamic property bond dissociation energy has been taken into account for the reactivity of the systems.View full textDownload full textKeywordsion beam mixing, metal/polymer system, swift heavy ion, bond dissociation energyRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/10420150.2011.572283
