Abstract
The effect of several metal substrates (A], Cu, Ag and Au) on the photodegradation of polyethylene terephthalate (PET) and polyvinylfluoride (PVF) films has been examined. The effect of M on M/PET systems under both oxidative and non-oxidative conditions shows that the orders of photodegradation are: Cu/PET»Al/PET>PET>Au/PET>Ag/PET (Non-oxidative) and Cu/PET>>>PET>Al/PET>Au/PET>Ag/PET (Oxidative) The effect of M on M/PVF films when irradiated under non-oxidative conditions shows that all metals have an adverse effect on the photodegradation of these films. Under oxidative conditions, Cu/PVF shows extreme photodegradation while the other M/PVF films show far less photodegradation than under the non-oxidative conditions. The trends in photodeg-radation are as follows: Al/PVF>>Cu/PVF>Au/PVF>Ag/PVF>PVF (Non-oxidative) and Cu/PVF»PVF>A1/PVF>Au/PVF>Ag/PVF (Oxidative)
