The development of holes of fission tracks in polyvinylidene fluoride (PVDF) has been attempted with several etchants and observed under an electron microscope. A certain period of immersion in alkaline solution caused the development of fission tracks, but the alkaline solution mixed with alcohol did not allow enlargement of the diameter of tracks to a significant width. A micrograph of TEM showed extreme swelling of the film. A saturated K2Cr2O7 in the concentrated solution of H2SO4 was short of dissolution for the film. With a saturated KMnO4 solution, thick layers were formed over the film. The mechanism of dissolution was presented tentatively in relation to the track etching. An organic solvent developed none of the distinct track figures.
