specific Embodiment approach 1

[0048] Specific Embodiment 1: This embodiment is a method for preparing a polyelectrolyte complex with a patterned micro-nano structure that responds to stress, and it is specifically completed in the following steps:

[0049] 1. Preparation of patterned PDMS stamps:

[0050] Mix polydimethylsiloxane prepolymer A and curing agent B, first stir at a stirring speed of 200r / min to 500r / min for 5min to 8min, then stir at a centrifugal speed of 3000r / min to 4000r / min Centrifuge for 5min to 8min to obtain a mixed solution; pour the mixed solution into a petri dish equipped with a patterned silicon substrate, and then vacuum cure the petri dish at a temperature of 60°C to 80°C for 1h to 3h to obtain on the silicon substrate Patterned PDMS stamp; peeling the patterned PDMS stamp from the silicon substrate to obtain a patterned PDMS stamp;

[0051] The mass ratio of prepolymer A and curing agent B of the polydimethylsiloxane described in step 1 is 10:1;

[0052] Two, the preparation ...

specific Embodiment approach 2

[0064] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the patterned PDMS stamp described in step 1 is a cube with a side length of 10 μm in the array. Others are the same as the first embodiment.

specific Embodiment approach 3

[0065] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the sodium chloride solution of polystyrene sodium sulfonate described in step 2 is polystyrene sodium sulfonate, sodium chloride and distilled water The mixed solution, the concentration of polystyrene sodium sulfonate in the sodium chloride solution of polystyrene sodium sulfonate is 2mg / mL, the concentration of sodium chloride is 2mol / L; the sodium chloride solution of the polyacrylate It is a mixed solution of polyacrylate, sodium chloride and distilled water, the concentration of polyacrylate in the sodium chloride solution of polyacrylate is 2mg / mL, and the concentration of sodium chloride is 2mol / L. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to a preparation method and application of a polyelectrolyte compound with a stress response and a patterned micro-nano structure, in particular to a preparation method and application of the polyelectrolyte compound. The invention aims to solve the problems that an existing humidity sensor is expensive, and a compound sensor cannot realize industrial production and is not provided with relative humidity, acidity and other detection indexes. The preparation method comprises the following steps of (1) preparing a patterned PDMS stamp; (2) preparing the polyelectrolyte compound; (3) pressurizing, keeping warm and transferring to obtain the polyelectrolyte compound with the stress response and the patterned micro-nano structure. The polyelectrolyte compound with the stress response and the patterned micro-nano structure is used as an intelligent super perspective material and a stress responsive scattering medium for application, is used for detecting life food quality, and is used for a humidity sensor. According to the preparation method provided by the invention, the polyelectrolyte compound with the stress response and the patterned micro-nano structure can be obtained.

Description

technical field [0001] The invention relates to a preparation method and application of a polyelectrolyte complex. Background technique [0002] With the development of modernization, whether it is scientific research or industrial production, it is difficult to find a field that has nothing to do with humidity sensing. In real life, cell culture or food and battery production need to control the humidity below 70-80% to prevent the growth of fungi and microorganisms and cause pollution. Appropriate air relative humidity can increase the comfort of life and improve health, while the air Too low relative humidity can cause chapped and itchy skin. Although the measurement and control of temperature is particularly important to human beings, so far the hygrometers with fast response speed, small size, good linearity and relatively stable humidity mainly come from Honeywell (Honeywell Corporation) in the United States and are expensive. However, the newly reported gold nanopar...
