The invention relates to polymer imprinted polymer films with trinitrotoluene, and to a process for their production, used in the field of electrochemical sensors of explosive detection. The polymeric films according to the invention are directly attached to a TiO support and have an Impression Factor F of 2.4 ... 4. The process according to the invention consists in depositing on the support of liquid films prepared from solutions of binary copolymers of acrylonitrile with methacrylic acid, itaconic acid or acrylic acid as well as trinitrotoluene, transformation into polymeric films by wet phase inversion, and extraction in ethanol of trinitrotoluene. |
