Changes in surface electric potential of P(VDF-TrFE 70:30) films deposited on glass substrate under influence of UV radiation were investigated. It was found that after 6 minutes of UV irradiation surface electric potential of the films decreased and no changes were observed further increasing irradiation time. Surface electric potential exponentially relaxed to its initial value within 30 min after the irradiation was stopped. The study suggests that P(VDF-TrFE 70:30) films deposited on glass substrate are sensitive to UV radiation and might be used as a material for an UV detector, however, further studies are required.
