The invention relates to a process for obtaining a sensitive layer for a humidity sensor. The process according to the invention consists in the preparation of polyaniline doped with HO-PEG12-propionic acid, to which pullulan PI-20 is added, under magnetic stirring for 8 hours; the solution is electrophilized and deposited on a polyethylene terephthalate substrate, resulting in a sensitive nano-fiber layer of polyaniline doped with HO-PEG 12-propionic acid and pullulan PI-20, which is dried in the oven at 70 ° C for 40 min. . |
