Quantitative explanation of the mechanism of corrosion of poly(tetrafluoroethylene) caused by active alkali metals
Tóm tắt
The known method of surface treatment of poly(tetrafluoroethylene) (Teflon) by alkali metals was studied quantitatively. It was shown that the reaction proceeds by an electrochemical mechanism in solid phase. The alkali metal acts as anode and Teflon as a cathodic active material of a typical galvanic corrosion cell. A relation describing the rate of the penetration of this reaction into the depth of Teflon was derived.
