Description

Technical Field

[0001] The invention belongs to the technical field of intelligent electrode materials, and specifically relates to a PEDOT / chitosan / TPEE composite skin-mimicking flexible intelligent electrode film and a preparation method thereof. Background Art

[0002] Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not just hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Wearable devices can overcome the shortcomings of current hospital monitoring equipment, such as bulky, complex wiring, and restrictions on patients' daily activities. However, most wearable devices are not widely used in hospital monitoring equipment due to immature technology.

[0003] The performance of smart materials has a great impact on wearable devices. Currently, smart materials are mainly composed of PVC (polyvinyl chloride) or silicone and a small amount of conductive material, but there are the following problems: (1) slow data transmission; (2) not antibacterial, which can easily cause rashes in patients; (3) small capacitance and short service life. In addition to the above three problems, smart electrode materials based on PVC materials also have the following shortcomings: (1) not environmentally friendly; (2) as the service life increases, they will age and stop working, and the electronic signal is easily interrupted, affecting monitoring.

[0004] Therefore, this application urgently needs to develop a new smart material that is more suitable for wearable devices. Summary of the invention

[0005] In order to improve the defects of existing smart electrode materials such as small capacitance and slow data transmission, the present application provides a PEDOT / chitosan / TPEE composite skin-mimicking flexible smart electrode film and a preparation method thereof.

[0006] In the first aspect, the present application provides a PEDOT / chitosan / TPEE composite skin-mimicking flexible intelligent electrode film, which is implemented by the following technical solution: A PEDOT / chitosan / TPEE composite skin-mimicking flexible intelligent electrode film, the preparation raw materials of which include:

[0007] By adopting the above technical solution, TPEE (thermoplastic polyester elastomer) as the base material of PEDOT / chitosan / TPEE composite skin-like flexible intelligent electrode film has excellent processing performance, flexibility, electrical properties and charge bearing capacity. Under the action of lubricant, TPEE makes PEDOT / chitosan / TPEE composite skin-like flexible intelligent electrode film fit well to the patient's skin, has the same skin color as real skin, and can well sense human body signs data. PEDOT (poly 3,4-ethylenedioxythiophene) has the advantages of low energy gap, low electrochemical doping potential, short response time, good stability, etc., and has excellent conductive properties. The addition of chitosan makes PEDOT / chitosan / TPEE composite skin-like flexible intelligent electrode film have antibacterial and self-cleaning effects, which can protect patients with skin allergies from rashes.

[0008] Importantly, during the research process, the applicant accidentally discovered that the combined effect of TPEE, chitosan and PEDOT not only improved the conductive and antibacterial properties of the PEDOT / chitosan / TPEE composite skin-mimicking flexible intelligent electrode film, but also improved the capacitance and code cloud transmission rate of the PEDOT / chitosan / TPEE composite skin-mimicking flexible intelligent electrode film. The capacitance reserve is large and can work stably for a long time. The code cloud transmission rate reaches the industry's front-end level and can transmit data in real time. Therefore, the PEDOT / chitosan / TPEE composite skin-mimicking flexible intelligent electrode film provided by the present application has excellent electronic properties, can send heart rate and other vital signs back to the monitoring terminal in time, better realize information exchange and interaction between doctors and patients, can effectively improve the defects of current modern hospital monitoring equipment, and give patients more freedom of movement and convenience. It has high social and economic benefits and broad market prospects.

[0009] The addition of foaming agent enables the PEDOT / chitosan / TPEE composite skin-mimicking flexible intelligent electrode film to achieve better water vapor exchange between the inner and outer layers of the film, keeping the patient's skin dry. The addition of antioxidant can improve the aging resistance of the PEDOT / chitosan / TPEE composite skin-mimicking flexible intelligent electrode film and increase its service life.

[0010] Preferably, the raw materials for preparing the PEDOT / chitosan / TPEE composite skin-mimicking flexible intelligent electrode film include: TPEE 95-100 parts; PEDOT 10-15 parts; Chitosan 10-12 parts; 1.4-3 parts of lubricant; 1.5 to 3 parts of foaming agent; 1.2-3 parts of antioxidant; 1.4 to 2 parts of pigment.

[0011] The PEDOT / chitosan / TPEE composite skin-like flexible intelligent electrode film within the above composition range has excellent conductivity and large capacitance reserve, which can increase the use time. The code cloud transmission rate reaches the industry's leading level, can transmit data instantly, and has a high sterilization rate, which can protect the patient's skin from allergies. It has a high air permeability, can keep the patient's skin dry, and is soft and close-fitting, which can better perceive human vital signs data.

[0012] More preferably, the raw materials for preparing the PEDOT / chitosan / TPEE composite skin-mimicking flexible intelligent electrode film include:

[0013] The PEDOT / chitosan / TPEE composite skin-like flexible intelligent electrode film with the preferred composition has a conductivity of 9.5×10 6 S / m, capacitance up to 8.2×10 7 μF, the code cloud transmission rate reaches 4800Baud, the sterilization rate reaches 97%, and the air permeability reaches 95%, and all performances are optimized.

[0014] Preferably, the hardness of the TPEE is Shore 50-60A.

[0015] By adopting the above technical scheme, TPEE with a hardness of 50-60A on Shore A has better flexibility and processability, which is conducive to the joint effect of TPEE, chitosan and PEDOT. TPEE at this hardness can make the PEDOT / chitosan / TPEE composite skin-like flexible intelligent electrode film better fit the patient's skin and better sense human vital signs data, further improving the code cloud transmission rate and capacitance of the PEDOT / chitosan / TPEE composite skin-like flexible intelligent electrode film.

[0016] Preferably, the number average molecular weight of the chitosan is 9,000 to 10,000.

[0017] By adopting the above technical scheme, chitosan with a number average molecular weight of 9000-10000 has a small molecular weight, which is conducive to the grafting of chitosan onto PEDOT, and the grafting rate is high, thereby improving the assembly stability of PEDOT / chitosan / TPEE, thereby improving the code cloud transmission rate, capacitance, conductivity and sterilization rate of the PEDOT / chitosan / TPEE composite skin-mimicking flexible intelligent electrode film.

[0018] Preferably, the lubricant is prepared by mixing ethylene bisstearamide, complex ester and silicone oil in a mass ratio of (3-4):(1-2):3.

[0019] By adopting the above technical scheme, the lubricant compounded with ethylene bisstearamide, complex ester and silicone oil has better compatibility with TPEE and chitosan, because ethylene bisstearamide contains two amide groups in its molecular structure and the complex ester contains fatty acids, alcohols and non-fat molecules, thereby improving the stability of the PEDOT / chitosan / TPEE composite skin-mimicking flexible intelligent electrode film, and making the conductivity, capacitance, code cloud transmission rate, sterilization rate and air permeability of the film better.

[0020] Preferably, the complex ester is prepared by mixing pentaerythritol monooleate, soybean lecithin and glyceroglycolipid in a mass ratio of 1:(0.1-0.2):(0.02-0.03).

[0021] By adopting the above technical solution, the composite ester compounded by pentaerythritol monooleate, soybean lecithin and glycerol glycolipid can improve the compatibility and cross-linking between the lubricant and TPEE and chitosan, while making the film more fit to the skin, better sensing human body sign data, improving the conductivity of the PEDOT / chitosan / TPEE composite skin-like flexible intelligent electrode film, increasing the capacitance reserve, and improving the code cloud transmission rate. And the composite ester is not easily oxidized in the air under the action of the antioxidant in this application.

[0022] Preferably, the silicone oil is a dihydroxy-terminated polyether modified silicone oil.

[0023] By adopting the above technical solution, the double-terminal hydroxyl polyether modified silicone oil is reactive and can form a more stable network structure with TPEE and chitosan, thereby improving the assembly stability of PEDOT / chitosan / TPEE, thereby improving the code cloud transmission rate and capacitance of the film.

[0024] Preferably, the raw materials for preparing the PEDOT / chitosan / TPEE composite skin-mimicking flexible intelligent electrode film further include 0.5 to 2 parts by weight of a mildew preventer.

[0025] By adopting the above technical solution, the addition of antifungal agent can further improve the antibacterial property of PEDOT / chitosan / TPEE composite skin-mimicking flexible intelligent electrode film together with chitosan.

[0026] In the second aspect, the present application provides a method for preparing a PEDOT / chitosan / TPEE composite skin-mimicking flexible intelligent electrode film, which is implemented by the following technical solution: A method for preparing a PEDOT / chitosan / TPEE composite skin-mimicking flexible intelligent electrode film comprises the following steps: TPEE, PEDOT, chitosan, a foaming agent, a lubricant, an antioxidant and a pigment are mixed to obtain a mixture, which is then kneaded and extruded into a film to obtain a PEDOT / chitosan / TPEE composite skin-mimicking flexible intelligent electrode film.

[0027] The preparation process of the PEDOT / chitosan / TPEE composite skin-mimicking flexible intelligent electrode film of the present application is simple, low-cost, and highly efficient, and can be directly extruded without the need for high-temperature shaping or mold pressurization.

[0028] In summary, this application has the following beneficial effects: 1. The PEDOT / chitosan / TPEE composite skin-like flexible intelligent electrode film of this application is soft and close-fitting, can better sense human vital signs data, has excellent conductive and antibacterial properties, has a large capacitance reserve, can work stably for a long time, and the code cloud transmission rate reaches the industry's front-end level. It can transmit data in real time, and send heart rate and other vital signs back to the monitoring terminal in time, so as to better realize information exchange and interaction between doctors and patients.

[0029] 2. The raw materials of the PEDOT / chitosan / TPEE composite skin-mimicking flexible intelligent electrode film of this application are simple and easy to obtain, environmentally friendly, antibacterial, self-cleaning, and do not cause allergic reactions.

[0030] 3. The present application uses chitosan with a number average molecular weight of 9000 to 10000, which is conducive to the grafting of chitosan onto PEDOT, improving the assembly stability of PEDOT / chitosan / TPEE, thereby improving the code cloud transmission rate, capacitance, conductivity and sterilization rate of the PEDOT / chitosan / TPEE composite skin-mimicking flexible intelligent electrode film.

[0031] 4. This application uses a lubricant composed of ethylene bisstearamide, complex ester and silicone oil to improve the stability of the PEDOT / chitosan / TPEE composite skin-mimicking flexible intelligent electrode film, making the film's conductivity, capacitance, code cloud transmission rate, sterilization rate and air permeability better.

[0057] Performance testing The following performance tests were performed on the films prepared in Examples 1-19 and Comparative Examples 1-3 of the present application and the commercially available smart wearable film of Comparative Example 4.

[0058] 1. Conductivity: The conductivity was tested using a conductivity meter. The test results are shown in Table 6.

[0059] 2. Capacitance: Use a multimeter to test the capacitance. The test results are shown in Table 6.

[0060] 3. Code cloud transmission rate: The film was used in a wearable device with a receiving device that automatically detects the code cloud transmission rate. The test results are shown in Table 6.

[0061] 4. Sterilization rate: The sterilization rate was tested according to the method of GB / T 37206-2018 “Test method for antibacterial properties of organic separation membranes”. The test results are shown in Table 6.

[0062] 5. Air permeability: The air permeability is tested using an air permeability tester. The test results are shown in Table 6.

[0063] Table 6 Test results The following describes the present application in detail with respect to the test data in Table 6.

[0064] From the test data of Example 1 and Comparative Example 4, it can be seen that the PEDOT / chitosan / TPEE composite skin-mimicking flexible intelligent electrode film prepared in the present application has excellent comprehensive performance, and its conductivity and capacitance are higher than similar products on the market, and are several orders of magnitude higher than similar products. It has good social benefits, fast code cloud transmission rate, and can transmit data instantly.

[0065] From the test data of Example 1 and Comparative Example 1, it can be seen that by replacing TPEE with PVC, the conductivity of the film is significantly reduced, and the capacitance and code cloud transmission rate are also significantly reduced. From the test data of Example 1 and Comparative Example 2, it can be seen that by replacing PEDOT with PANI, the capacitance and code cloud transmission rate of the film are significantly reduced, while the conductivity is only slightly reduced. From the test data of Example 1 and Comparative Example 3, it can be seen that by replacing chitosan with the antibacterial agent KJAT-K01, the capacitance and code cloud transmission rate of the film are significantly reduced, and the sterilization rate is slightly improved. It shows that in the system of this application, TPEE not only has a conductive effect, chitosan has an antibacterial effect, and PEDOT has a conductive effect, but the combined effect of TPEE, chitosan and PEDOT can significantly improve the capacitance and code cloud transmission rate of the film.

[0066] From the test data of Examples 1-5, it can be seen that the performance of the PEDOT / chitosan / TPEE composite skin-like flexible intelligent electrode film corresponding to Example 5 is better, and the conductivity is 9.5×10 6 S / m, capacitance up to 8.2×10 7 μF, the code cloud transmission rate reaches 4800Baud, the sterilization rate reaches 97%, and the air permeability reaches 95%.

[0067] From the test data of Examples 5-7, it can be seen that the code cloud transmission rate and capacitance of the film corresponding to TPEE with a hardness of Shore 70A are significantly lower, and the conductivity is also slightly reduced. This is because the flexibility and processability of TPEE with this hardness are poor, which is not conducive to the film fitting the patient's skin and the synergistic effect of TPEE, chitosan and PEDOT.

[0068] From the test data of Examples 6, 8-9, it can be seen that chitosan with a number average molecular weight of 50,000 has a large molecular weight, which is not conducive to the grafting of chitosan on PEDOT, reduces the grafting rate of chitosan, and has poor stability of the film, so that the code cloud transmission rate, capacitance, conductivity and sterilization rate of the film are all low.

[0069] From the test data of Examples 8, 10-13, it can be seen that the lubricant compounded with ethylene bisstearamide, complex ester and silicone oil improves the conductivity, capacitance, code cloud transmission rate, sterilization rate and air permeability of the PEDOT / chitosan / TPEE composite skin-mimicking flexible intelligent electrode film.

[0070] From the test data of Examples 10, 14-15, it can be seen that Example 15 adopts a lubricant compounded with double-terminated hydroxyl polyether modified silicone oil SF-8427, ethylene bisstearic acid amide and complex ester. Compared with dimethyl hydroxyl silicone oil and polyether modified silicone oil SC-12847, double-terminated hydroxyl polyether modified silicone oil has stronger reaction activity. Double-terminated hydroxyl polyether modified silicone oil can form a more stable network structure with TPEE and chitosan, thereby improving the assembly stability of PEDOT / chitosan / TPEE, thereby improving the code cloud transmission rate and capacitance of the film.

[0071] From the test data of Examples 15-18, it can be seen that the complex ester prepared by compounding pentaerythritol monooleate, soybean lecithin and glyceroglycolipid has good compatibility with TPEE and chitosan, and improves the conductivity, capacitance and code cloud transmission rate of the film.

[0072] From the test data of Examples 18 and 19, it can be seen that there is no free carboxyl group in pentaerythritol tetraoleate, while pentaerythritol monooleate has three free carboxyl groups. The corresponding complex ester of pentaerythritol monooleate can improve the crosslinking between the lubricant and TPEE and chitosan, thereby improving the conductivity, capacitance and code cloud transmission rate of the film.

[0073] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
