Description

Technical Field

[0001] The present invention relates to the technical field of ammonia detection materials, and in particular to a preparation method and application of a washable, anti-fatigue, environmentally friendly smart textile for detecting ammonia. Background Art

[0002] In industrial production and daily life, ammonia is a common harmful gas, and its leakage and diffusion problems are increasingly concerned. High concentrations of ammonia not only pollute the environment, but also cause serious harm to human health, such as respiratory diseases and other health problems. Traditional ammonia detection methods mainly rely on fixed sensors and portable detection equipment. Although these devices can provide accurate detection data, there are many bottlenecks in practical applications. Fixed sensors are difficult to cover large areas and require frequent maintenance, which increases the cost of use. Although portable detection equipment is flexible, it is cumbersome to operate and requires manual detection, and cannot achieve real-time and continuous monitoring. In addition, these devices are often large in size, difficult to integrate into daily wear, and inconvenient to use. In order to overcome these bottlenecks, researchers began to explore new ammonia detection methods. Smart textiles, as a new type of detection material, realize real-time monitoring of ammonia by integrating ammonia sensors and conductive materials into textiles. Compared with traditional methods, smart textiles have the advantages of being soft, lightweight and wearable, and can provide continuous environmental monitoring in daily use. At the same time, in order to meet the actual use needs, this smart textile is designed to be washable, anti-fatigue and environmentally friendly. Its washable properties ensure that the textiles can maintain their functions after multiple washings, its anti-fatigue properties make it less likely to be damaged during long-term use, and its environmentally friendly properties reduce the negative impact on the environment. By using nanotechnology to improve the sensitivity and selectivity of sensors and by using multifunctional coatings to enhance the mechanical properties and durability of textiles, researchers have made smart textiles show broad application prospects in environmental monitoring, industrial safety, and personal health. This interdisciplinary research result not only promotes the development of smart material technology, but also provides a new path for achieving more efficient ammonia detection.

The above process was protected with tin foil to prevent light; finally, after washing with deionized water and drying, polydopamine-modified bamboo fiber cloth (PDA-BF) was obtained.

[0051] Comparative Example 3: Untreated bamboo fiber cloth textile

[0052] The textile fabric is washed alternately with deionized water and alcohol; and the textile fabric is obtained after drying.

[0053] The washable, anti-fatigue, and environmentally friendly smart textile for detecting ammonia prepared in Example 1 was characterized in structure. Figure 1 As shown; Figure 1 The microstructure of the textile PANI-PDA-BF of Example 1: The observation of the microstructure shows that the original bamboo fiber cloth is composed of randomly arranged fibers with a diameter of about 10 μm; after PDA modification, a polymer coating appears on the fiber surface; after the introduction of PANI, an obvious particle structure appears on the fiber surface. The above results show that the PANI-PDA-BF material was successfully prepared.

[0054] The smart textiles of Example 1 and Comparative Example 1 were placed in a gas-sensitive detection system (i.e., the NH3 sensing test was carried out in a 10L test chamber at room temperature: the smart textile with a size of 2.5 cm×1 cm was connected to a data acquisition device DAM-3153 through gold-plated clips at both ends; a certain volume of 99.9% high-purity ammonia water was injected into the test chamber, and the NH3 response performance was evaluated by in-situ recording of resistance changes under air environment, 25°C, 50% RH conditions). As the ammonia concentration changed (10ppm, 20ppm, 30ppm, 50ppm and 120ppm) ( Figure 2 a), to measure the resistance of the smart textiles of Example 1 and Comparative Example 1; the experimental results are as follows Figure 2 As shown in Fig. 2a, it is found that the resistance / initial resistance change value of the smart textile shows a good linear change trend with the ammonia concentration. The difference is that the slope of the fitting function of Example 1 is significantly higher than that of Comparative Example 1 ( Figure 2 ), indicating that Example 1 has a higher sensitivity to ammonia.

[0055] The smart textiles of Example 1 and Comparative Example 1 were placed in a magnetic stirrer at a stirring rate of 120 rpm for 10 minutes, and then dried naturally; after washing three times in a row, the samples were taken out for testing.

[0056] The experimental results are as follows Figure 3 As shown, Figure 3 a is the conductivity of the smart textile prepared in Example 1 (after washing) changing with time at different concentrations, Figure 3 b is a washing resistance evaluation test of the smart textile prepared in Example 1; from the response curve of the smart textile to ammonia water, it can be found that the comparative example 1 and Example 1 can still respond to ammonia water after washing; but from the response behavior of the smart textile to ammonia water ( Figure 3 ) It can be found that the response of comparative example 1 to ammonia water is significantly reduced after washing (the slope is reduced from 0.02 to 0.01), while the effect on example 1 is relatively small (the slope is reduced from 0.09 to 0.08). These results prove that the present invention has good anti-washing performance.

[0057] The smart textiles of Example 1 and Comparative Example 1 were put into a Shimadzu fatigue testing machine for experiment. The samples were cut into 10 cm × 2 cm strips and clamped at both ends of the fatigue testing machine. Sensors were connected at both ends to record the resistance change process in real time. The strain was set to 5%, and the two samples were subjected to cyclic tensile loading (5 Hz). After 10,000 times, the samples were taken out for testing. The experimental results are shown in Figure 2. Figure 4 As shown in Figure 1, tensile load is one of the main loads faced by textile-based sensing materials in actual service. The resistance of the smart textile (Example 1, Comparative Example 1) still changes with the change of ammonia. The difference is that after being stretched 10,000 times, the response behavior of Comparative Example 1 is significantly lower than that of Example 1 ( Figure 4 ). These results show that the smart textiles of the present invention have excellent fatigue resistance.

[0058] The smart textiles prepared in Example 1, Comparative Example 1, Comparative Example 2, and Comparative Example 3 were cut into discs with a diameter of 10 mm and sterilized by immersing in alcohol. The 3T3 fibroblast suspension was cultured at 5×10 4 / portion were inoculated into the sample, and the adhesion behavior of the cells was observed by laser confocal microscopy (CLSM) after 3 days of co-culture. The degradation characteristics of the smart textiles were evaluated by the mass loss rate after 28 days of degradation ( Figure 5 e is the degradation status of the smart textile in Example 1).

[0059] The experimental results are as follows Figure 5 As shown in Figure 3, bamboo fiber is mainly composed of cellulose and contains abundant active functional groups, such as hydroxyl and epoxy, which are beneficial to the adhesion of cells on BF. Since PDA has excellent cell adhesion promoting properties, cells show good adhesion behavior on PDA-BF. Figure 5 a is the textile of Comparative Example 3; Figure 5 b is the textile of comparative example 2; Figure 5 c is the textile of Example 1; Figure 5 d is the textile image of comparative example 1. From the cell adhesion photos, it can be seen that BF is conducive to cell adhesion, PDA has excellent cell adhesion promotion performance, PANI has fewer surface active functional groups, and fewer cells adhere to PANI-PDA-BF and PANI-BF. In short, the PANI-PDA-BF smart textile of Example 1 has no obvious biological toxicity and can be used for respiratory monitoring textiles. In addition to good biocompatibility, Example 1 also shows good degradation characteristics, with a degradation rate of about 17% after 28 days ( Figure 5 e). In conclusion, the present invention has good biocompatibility and biodegradability.

[0060] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
