This letter describes the increase in electrical conductivity of poly͑vinylidene fluoride͒ induced by excimer laser irradiation with = 248 nm. The electrical conductivity was found to increase from 10 −13 to 10 −4 ⍀ −1 cm −1 . As a result, experiments produced a transition in the property of the material from an insulator to a conductor. Optimal conditions for laser irradiation were determined in terms of the laser energy density, the repetition frequency, and the total number of laser shots.
