[0002] Multifunctional vapor phase corrosion inhibitor films, as a novel type of rust-preventive material, have been widely used in recent years. They achieve rust prevention by adding vapor phase corrosion inhibitors to the film, which then volatilize at room temperature, forming a protective film on the metal surface. These films offer advantages such as ease of use, no impact on the appearance and performance of metal products, and recyclability. However, current multifunctional vapor phase corrosion inhibitor films lack sufficient intelligence and data transmission capabilities, thus failing to automatically adjust their rust-prevention strategies based on actual conditions, presenting certain problems.

The barrier layer is pressed onto one side of the base layer, and the composite layer is disposed on the other side of the base layer. The composite layer consists of a temperature sensor, a corrosion potential monitoring electrode, a pH sensor, and a circuit layer. The protective layer is disposed on the side of the composite layer away from the base layer and consists of a hydrophobic layer, a deposition layer, and a load layer.

[0006] The present invention is further configured such that the corrosion potential monitoring electrode includes a silver chloride reference electrode.

[0007] The present invention is further configured such that the pH sensor is composed of a bromothymol blue layer and a pH-sensitive dye layer.

[0008] The present invention is further configured such that: the circuit layer includes interdigitated electrodes printed with silk-smooth lines, and a plurality of interdigitated electrodes are provided to form an interdigitated electrode array.

[0009] The present invention is further configured such that the load layer is composed of an electrospinning layer and a PVA layer.

[0010] The present invention is further configured such that the hydrophobic layer is a perfluoropolyether layer.

[0011] The beneficial effects of this invention are: by setting a temperature sensor, corrosion potential monitoring electrode, pH sensor and circuit layer inside the anti-rust film, the composite layer can realize the ability of real-time environmental perception and feedback, and realize data transmission, so that users can adjust the anti-rust strategy according to real-time data.

[0014] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0015] like Figure 1 As shown, a multifunctional vapor phase rust inhibitor film includes a base layer 1, a barrier layer 2, a composite layer 3, and a protective layer 4. The barrier layer 2 is pressed onto one side of the base layer 1, and the composite layer 3 is disposed on the other side of the base layer 1. The composite layer 3 consists of a temperature sensor, a corrosion potential monitoring electrode, a pH sensor, and a circuit layer. The protective layer 4 is disposed on the side of the composite layer 3 away from the base layer 1, and the protective layer 4 consists of a hydrophobic layer, a deposition layer, and a load layer.

[0016] Barrier layer 2 contains PLA and SiO2. Barrier layer 2 is formed by mixing nano-SiO2 into PLA during melt extrusion and casting. PLA is a biodegradable polymer made from corn starch or fermented sugarcane. It is biodegradable, puncture-resistant, and resistant to high and low temperatures, and can effectively block the penetration of corrosive substances such as water vapor, oxygen, and chloride ions.

[0017] A temperature sensor is formed by combining a graphene layer and a polypyrrole composite film.

[0018] The silver chloride reference electrode is used as the corrosion potential monitoring electrode in composite layer 3.

[0019] A pH sensor is formed by combining a bromothymol blue layer and a pH-sensitive dye layer.

[0020] Several interdigitated electrodes are screen-printed onto a substrate to form an interdigitated electrode array, ultimately creating a circuit layer. Through a temperature sensor, corrosion potential monitoring electrode, pH sensor, and the circuit layer, composite layer 3 achieves real-time environmental sensing and feedback capabilities, and enables data transmission, allowing users to adjust their rust prevention strategies based on real-time data.

[0021] An electrospinning layer is used to deposit a PVA solution containing a pH-responsive vapor phase corrosion inhibitor onto the circuit layer to form a load layer, which allows the circuit layer to release the vapor phase corrosion inhibitor. Then, an indicator is used to coat the surface of the circuit layer.

[0022] After the composite layer 3 and the protective layer 4 are pressed together with the base layer 1, a perfluoropolyether solution is sprayed on the outside of the load layer to form a perfluoropolyether layer.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
