Abstract

Peel strength values of sodium-etched poly(tetrafluoroethylene) film bonded to polyurethane substrates have been monitored and found to decrease as a function of exposure to ultraviolet radiation. Attenuated total reflectance (ATR) spectra were monitored on unbonded sodium-etched poly(tetrafluoroethylene) surfaces for the same environmental aging conditions and were found to vary significantly in the region of 1650 cm⁻¹. Techniques are proposed to retard UV-initiated etch degradation and thereby prolong bond integrity.
