要約(英語): The adhesive strength doesn't improve so much even if the surface is activated. It is known that PTFE (polytetra fluoroethylene) is one of the collapse type polymer since the binding energy of main chain is smaller than that of side chain. Accordingly, it is assumed that adhesive strength may improve by suppressing the collapse of structure. It is also expected that introduction of cross-linking structure may suppress the collapse of structure. It was confirmed that a lot of polar radicals were introduced at the surface by nitrogen ion irradiation around 30 eV. Thus, to introduce the cross-linking structure several 100 eV nitrogen ions were irradiated after irradiation of nitrogen with 30 eV ion. As a result, adhesive strength irradiated by 300 eV improved more than that of 1000 eV. From the result of XPS (X-ray-Photoelectron-Spectroscopy) analysis, many C-N-C bonds contributing cross-linking structure was detected at a shallow layer by irradiation of ions with 300 eV. From these results, it is concluded that the depth of cross-link formation is important to improve the adhesive strength.
