“…This suggests that in alkali etching of irradiated films, the alkali acts as an initiation agent, destroying traps in the core and triggering electron catalysis that vastly speeds up the fragmentation of the PET chain molecules in the latent track cores. We believe that this electron catalysis in the cores explains the huge difference in the etching rates of irradiated PET films along and across the direction of the irradiating ion paths [ 47 ].…”

“…We will cite some publications in which similar estimates were obtained for PET membranes. Measurements of enhanced conductivity as a function of KCl concentration in cylindrical pores as small as 15 and 30 nm in diameter yielded a fixed charge density of 0.5 e nm −2 [55]. The reversible ionic dye binding applied to PET membranes with micro-pores resulted in a COOH-group surface density of 0.3 nm −2 [56].…”

“…For the surface charge density, we have considered the values r = -0.1 and -0.5 e/nm 2 , which are equivalent to fixed charge concentrations X : -2r/FR p = 0.11 and 0.55 M. These values are typical of nanopores (Westermann-Clark and Christoforou 1986; Apel and Pretzsch 1986;Manzanares et al 1991;Ramírez et al 2003b;Chun et al 2006;Ku et al 2007). The external electrolyte concentrations have been assigned values between 0 and 0.8 M. The radii ratio R i /R p assumes values ranging from 0 (point ions) to 0.1 (R i = 0.3 nm).…”
