Description
Technical Field
The invention belongs to the field of inorganic functional polymer materials, and particularly relates to a preparation method of nickel polyphosphate inorganic hydrogel with a super-stretching property.
Background
In recent years, a soft robot has been developed as a research hotspot. Hydrogel sensors are important research objects in the field of soft robots, can convert detected external mechanical deformation (such as stretching, compression, bending and the like) into recordable electrical signals (such as current, resistance and capacitance), and are widely applied to the fields of electronic skin, health monitoring and the like. At present, most of hydrogel-based sensors are formed by doping different conductive fillers (such as metal, carbon nanotube, graphene, conductive polymer and electrolyte) into a flexible polymer matrix to construct a high-performance strain sensor. Under the action of external mechanical strain or stress, the interface resistance between the conductive fillers can change, and further, the change of electrical signals is caused. Although such sensors have a high sensitivity, their maximum elongation at break does not exceed 100%, which limits the use of hydrogel sensors under more extended conditions.
In order to impart high tensile properties to hydrogels, double-network hydrogels have been developed. Dual-network hydrogels are formed by the chemical and physical crosslinking (e.g., ionic interactions, hydrogen bonding, hydrophobic interactions) of at least two polymer chains to form an interpenetrating network. Under the action of external force, the weaker first-layer network is greatly damaged, and a large amount of energy is dissipated; the layer two network maintains structural integrity and continues to be stretched. Finally, a hydrogel with higher tensile properties is obtained. However, the preparation process of the double-network hydrogel is often complicated. At present, a simple and easy-to-operate method for preparing the super-stretched hydrogel is needed.
Disclosure of Invention
The invention aims to provide a preparation method of nickel polyphosphate inorganic hydrogel with super-stretching property aiming at the problems of poor elongation at break and complicated preparation process of the existing conductive hydrogel material.
The embodiment of the invention provides a preparation method of nickel polyphosphate inorganic hydrogel with a super-stretching property, which comprises the following steps:
step 1: adding ammonium polyphosphate into deionized water, and uniformly stirring to obtain an ammonium polyphosphate suspension;
step 2: adding sodium chloride into deionized water to obtain a sodium chloride solution, and adding the sodium chloride solution into the ammonium polyphosphate suspension to obtain the mixture solution;
and step 3: adding nickel chloride into deionized water to obtain a nickel chloride solution, and adding the nickel chloride solution into the mixture solution under the stirring or ultrasonic condition to generate a crosslinking effect to form an agglomerate. And collecting the agglomerates, and standing for 8-12 hours in a sealed glass ware to obtain the nickel polyphosphate inorganic hydrogel. Wherein, the molar ratio of nickel ions in the nickel chloride to phosphate ions in the ammonium polyphosphate is more than 1:2.
On the basis of the technical scheme, the invention can be improved as follows.
Further, the polymerization degree of the ammonium polyphosphate is more than 1000.
Furthermore, the mass ratio of the sodium chloride to the ammonium polyphosphate is 1:3-5:3.
Further, the mass ratio of the sodium chloride to the ammonium polyphosphate is 2:3.
The beneficial effects of the invention are: the nickel polyphosphate inorganic hydrogel prepared by the invention has a dynamic interaction between nickel ions and phosphate ions in a network structure, and has a super-stretching property and a self-repairing property. Free ions (such as Ni) in the network structure of nickel polyphosphate inorganic hydrogel 2+ ,Na + ,Cl - ) Is conductive and sensitive to strain response. The single physical crosslinking conductive hydrogel provided by the invention has the advantages of simple preparation method, easy operation, no involvement of complicated molecular design, synthesis and preparation processes, outstanding performance, and super-stretching performance (stretching ratio) compared with the common conductive hydrogel>6000). The conductive hydrogel with the super-stretching performance and the self-repairing performance has potential application value in a wide field.
Detailed Description
The principles and features of this invention will now be described in the following examples, which are intended to be illustrative only and are not intended to limit the scope of the invention.
Example 1:
1. 2.91g of commercially available ammonium polyphosphate with a degree of polymerization of >1000 was weighed using an analytical balance, added to 250mL of deionized water, and stirred magnetically at room temperature to obtain an ammonium polyphosphate suspension.
2. 1.94g of sodium chloride is weighed by an analytical balance, dissolved in 50mL of deionized water at room temperature with stirring, and then the sodium chloride solution is added to the ammonium polyphosphate suspension obtained in step 1 to promote the dissolution of ammonium polyphosphate.
3. 4.99g of nickel chloride hexahydrate is weighed by an analytical balance, dissolved in 210mL of deionized water at room temperature under magnetic stirring, and added to the solution obtained in the step 2 under stirring.
4. After the nickel chloride solution is added, green agglomerates are generated, the upper layer solution is poured, the agglomerates are collected and are placed in a sealed glass ware for standing for 8-12 hours, and the green nickel polyphosphate inorganic hydrogel is obtained.
In the above examples, the polymerization degree of the ammonium polyphosphate and the type of the nickel chloride may also be specifically selected according to the actual needs of the skilled person. Further, if the content of nickel ions is too small, effective coordination with phosphate ions cannot be achieved. The molar stoichiometric ratio of nickel ions to phosphate ions should be greater than 1:2. In addition, the agglomerates formed by crosslinking due to the coordination of nickel ions and phosphate ions need to be left in a sealed glass vessel for 8-12 hours to achieve a more uniform state.
Example 2:
1. 2.91g of commercially available ammonium polyphosphate with a degree of polymerization of >1000 was weighed using an analytical balance, added to 250mL of deionized water, and stirred magnetically at room temperature to obtain an ammonium polyphosphate suspension.
2. 1.94g of sodium chloride is weighed by an analytical balance, dissolved in 50mL of deionized water at room temperature with stirring, and then the sodium chloride solution is added to the ammonium polyphosphate suspension obtained in step 1 to promote the dissolution of ammonium polyphosphate.
3. 7.13g of nickel chloride hexahydrate is weighed by an analytical balance, dissolved in 300mL of deionized water at room temperature under magnetic stirring, and added to the solution obtained in the step 2 under stirring.
4. After the nickel chloride solution is added, green agglomerates are generated, the upper layer solution is poured, the agglomerates are collected and are placed in a sealed glass ware for standing for 8-12 hours, and the green nickel polyphosphate inorganic hydrogel is obtained.
The method for measuring the stretching ratio of the nickel polyphosphate inorganic hydrogel with the super-stretching property, which is prepared by the embodiment, comprises the following steps:
due to the limitation of the range of instruments, the nickel polyphosphate inorganic hydrogel prepared by the above embodiment is selected to be manually stretched by the invention. Calculating a stretching ratio (lambda) by a secondary stretching method:λ＝(l/l 0 )(l'/l 0 ') wherein l 0 Is the initial length of the first stretch,/, is the terminal length of the first stretch,/ 0 'is the initial length of the second stretch, and l' is the terminal length of the second stretch.
First, a small piece of gel (m =0.15 g) was clamped at both ends with two forceps (initial length l) 0 1 mm) and after stretching to 200mm, the middle section (l) is cut 0 '=30 mm) and stretching is continued until break (l' =1000 mm). The tensile ratio of the nickel polyphosphate inorganic hydrogel prepared in this example was calculated>6000。
In addition, the self-repairing performance test of the nickel polyphosphate inorganic hydrogel prepared in the embodiment includes the following steps:
the nickel polyphosphate inorganic hydrogel prepared in the example 2 is cut into two parts, then the sections are combined together, and the hydrogel is self-repaired for about 30 seconds at room temperature, so that a complete hydrogel can be obtained. The repaired nickel polyphosphate inorganic hydrogel is stretched within 100 times, and no fracture is observed, which shows that the nickel polyphosphate inorganic hydrogel prepared by the method has excellent self-repairing performance, and is beneficial to the dynamic crosslinking effect between nickel ions and phosphate ions.
The conductivity of the nickel polyphosphate inorganic hydrogel prepared in example 2 was tested, and the method steps were as follows:
two ends of the nickel polyphosphate inorganic hydrogel prepared in the example 2 are connected with leads and connected with an LED lamp to form an electric loop, and the normal work of the LED lamp can be observed, which shows that the nickel polyphosphate inorganic hydrogel prepared in the invention has conductivity. This is due to the presence of free mobile ions (e.g., ni) in the nickel polyphosphate inorganic hydrogel network 2+ ,Na + ,Cl - ). When the nickel polyphosphate inorganic hydrogel is stretched, the brightness of the LED lamp becomes dark, which indicates that the resistance of the nickel polyphosphate inorganic hydrogel is increased in the stretching process. This is because the ion channels in the hydrogel network become longer and the migration rate becomes slower during the stretching process. The result further shows that the nickel polyphosphate inorganic hydrogel prepared by the invention has strain response performance, which is super-response performanceThe development of stretched hydrogel sensors opens new ideas.
Example 3:
1. 0.49g of commercially available ammonium polyphosphate with a polymerization degree of more than 1000 was weighed by an analytical balance, added to 45mL of deionized water, and magnetically stirred at room temperature to obtain an ammonium polyphosphate suspension.
2. 0.33g of sodium chloride is weighed by an analytical balance, dissolved in 5mL of deionized water at room temperature with stirring, and then the sodium chloride solution is added to the ammonium polyphosphate suspension obtained in step 1 to promote the dissolution of ammonium polyphosphate.
3. 11.9g of nickel chloride hexahydrate is weighed by an analytical balance, dissolved in 500mL of deionized water at room temperature under magnetic stirring, and added to the solution obtained in the step 2 under stirring.
4. After the nickel chloride solution is added, green agglomerates are generated, the upper layer solution is poured, the agglomerates are collected and are placed in a sealed glass ware for standing for 8-12 hours, and the green nickel polyphosphate inorganic hydrogel is obtained.
