FIELD: chemistry.
SUBSTANCE: on the surface of the substrate by lifting it in a horizontal position at a constant speed, ranging from 4⋅10-5 up to 9⋅10-5 m/s, a film of poly (N,N-dimethyl-N,N-dimethylamino) -acetate is applied from an aqueous solution of the reacting components: a polymer such as poly-N,N-dimethyl-3,4-dimethylenepyrrolidium chloride (PDMPC) and a potassium hexacyanoferrate (II) 3,4-dimethylenepyrrolidinium cyanide (PHDMPC). The content of PDMPC in the solution is from 0.2 to 0.5 wt %, when the weight ratio of the modifier: polymer is equal to (2.3±0.1):1.
EFFECT: increasing the response, microhardness, homogeneity, and sensitivity of the film to the content of water vapour in the air, increasing the shelf life of the resulting heterostructure.
