Description
Technical Field
The invention relates to the technical field of preparation of nano materials, in particular to a preparation method and application of silver nanowires.
Background
The silver nanowire is a typical one-dimensional noble metal nanowire which has excellent optical, electrical, flexibility and thermal properties, and is a noble metal nano material mainly researched at present with the copper nanowire and the gold nanowire. Compared with copper nanowires, silver nanowires have good stability, are not easily oxidized by air, and are beneficial to wide application; compared with gold nanowires, gold nanowires are not prepared on a large scale as silver nanowires or copper nanowires at present because the preparation process of gold nanowires is complex and the yield is always low. Therefore, silver nanowires are a novel functional material most likely to be practical in noble metal nanowires.
At present, the application research of silver nanowires mainly focuses on the field of optoelectronics, such as the preparation of transparent conductive electrodes; the field of intelligent wearable equipment, such as electronic skin, ultrasensitive physiological detectors and the like; the electric heating field, such as heating film, defogging film, etc. and fuel cell catalyst.
The preparation method of silver nano-wire mainly includes hydrothermal method, microwave auxiliary method, ultraviolet reduction method, hard template method and electrochemical deposition method, among them, the polyol method proposed by professor of summer boy of university of california rational engineering is a method which is currently very widely applied, this method mainly uses polyol (such as ethylene glycol, glycerol, etc.) as solvent, through adding metal salt (such as silver nitrate), depending on the reducibility of polyol to reduce it into elementary substance nano-particles, the precipitation process of these nano-particles will produce super-symmetrical cubic structure unit cells, these unit cells as the seeds of growing nano-wire are dispersed in the solution, then by the action of surfactant, and further grow along a certain specific direction, thus get oriented growth nano-material, for example, polyvinylpyrrolidone is often added as surfactant in the above-mentioned reaction, the silver nanoparticle has a selective passivation effect, has a strong coating effect on the { 100 } crystal face group of the silver nanoparticle, and has a weak coating effect on the { 111 } crystal face group, so that the silver nanoparticle added with polyvinylpyrrolidone can continue to grow along the { 111 } crystal face group.
In the above method, the general process flow is as described above, but the inventor found a serious problem in using the method, that is, after the reaction is finished, the silver nanowires are washed from the mother liquor by centrifugation and then the mother liquor is directly poured out. In the process, the reaction mother liquor is greatly wasted, meanwhile, the poured reaction mother liquor also contains a large amount of available substances, and if the method is used for scale production, the pressure on subsequent wastewater treatment is also high, and the requirement of current recyclable development is not met.
Therefore, the invention aims to solve the problems, realize the emission reduction of the mother solution in the preparation process of the silver nanowires and reduce the cost for preparing the silver nanowires, and particularly provides the patent application of the invention.
