| 제목 | Surface modification of Poly(tetrafluoro ethylene) films by low energy ion-beam irradiation and its effect on the adhesion with copper |
| 초록 | In order to improve the adhesion between poly(tetrafluoroethylene)(PTFE) and copper, PTFE film was modified by Ar+ ion-beam irradiation with and without O2, NH3 environment, respectively. The modification process involves the introduction of functional groups via chemical reaction on the surface of PTFE. The surface of PTFE showed a grass-like structure by the sputtering effect of collision of ions on the PTFE surface. The contact angle between water droplet and PTFE surface increased with irradiation time owing to the effect of surface roughness. The XPS results showed that defluorination and oxidation occurred on the PTFE surface during the modification. The degree of those can be explained by radical concentration measurement. The adhesion test using T-peel method was conducted on PTFE/copper adhesive joints. The adhesion strength also increased with the irradiation time because of the increase of surface roughness and surface functionalization. From the XPS analysis, the failure was occurred in the inner layer of the PTFE rather than at the interface between the PTFE and copper layers for the ion-beam irradiated PTFE/copper adhesive joint. |
