Thermally cured poly(acrylic acid) (PAA) and poly(allylamine hydrochloride) (PAH) mulitlayer films on SiO2 using methylene blue dye (MB) as an indicator were studied to determine their stability when exposed to heat and humidity. Polyamide films of varying thicknesses were examined as functions of immersion times in MB solution, curing times, and curing temperatures. Artificial aging of the films demonstrated which were best suited to retain absorbed MB.
