Webacidic permanganic etching solution . Best maintaining time depends on the plastic ' s nature . It is enough 5 - 20 min . for ABS and PC / ABS plastics , while PEI or PEEK are etched much longer . The etching solution is free of strong inorganic acids , so even if the etching time exceeds the recommended , there is no risk of overetching . WebTherefore, the PEEK 150PF film prepared by isothermal crystallization was chosen as an ideal sample for AFM study. Fig. 7(a) and (b) show the AFM images obtained from the as-prepared melt crystalized PEEK 150PF film (no etching applied prior to AFM scanning). As can be seen, the AFM images again suggest the presence of the nodular crystals. springfield xd custom parts
