Fig. 2: Progression of sorption parameters for increasing UV-radiative exposure.
From: Photo-oxidation of PE-HD affecting polymer/fuel interaction and bacterial attachment
In a the normalized equilibrium concentrations and in b the normalized diffusion coefficients for UV-radiative exposures up to 460 MJ m−2 of PE-HD1 and PE-HD2 are shown. The immersion temperature was T = 60 °C using a plane sheet geometry (h = 1 mm). Sorption parameters are normalized to their initial values (indicated by an asterisk) to highlight the differences.
