Times Cited Count：2 Percentile：22.89(Instruments & Instrumentation)Poly(vinylidene-fluoride) (PVDF) film is suitable for investigation of the size of etchable ion tracks because we can clearly judge the finish of the track etching and the surrounding bulk area remains due to the high chemical stability. Thereby we can measure the radius of ion tracks of each ion. In this study, we focused on two irradiation conditions for controlling the size of etchable ion tracks of PVDF films. One was irradiation in an oxygen atmosphere and the other was a fullerene (C
) cluster beam irradiation. SEM observation showed that the size of pores became larger by irradiation in an oxygen atmosphere. It was found that the oxidation of ion tracks widened the size of etchable ion tracks. The C irradiation caused larger etchable tracks on the PVDF surface. The result could represent the effect of local and simultaneous collisions by the swift aggregated ions.

We investigated the track-etched surface of PVDF films irradiated with C cluster ions, comparing the data with C monoatomic ions. PVDF films were irradiated with 6 MeV C cluster ions. The energy of the each carbon ion is 100 keV/atom; thus, for comparison, the PVDF films were also irradiated with 100 keV C ions. SEM and AFM observation showed that the surface irradiated with C cluster ions apparently possessed flat-bottomed pores with an average diameter and depth of approximately 400 and 250 nm, respectively. On the other hand, track-etched pores were also formed on the surface irradiated with C ions, but their morphology was irregular or obscure. In the irradiation with the C cluster ions, the surface diameter of track-etched pores increased with increasing the etching time. The tracks of the 100 keV C ions seemed to be hardly developed by the etching when the time. In conclusion, the C cluster ions irradiation caused a large size of etchable tracks on the PVDF surface. The result could represent the effect of local and simultaneous collision by the aggregated ions.
