Description
The technical field is as follows:
the invention belongs to the field of advanced material manufacturing, and particularly relates to a method for digitally controllable printing of Ag nanowires.
The background art comprises the following steps:
with the progress of science and technology, optoelectronic devices are developed towards miniaturization, lightness and foldability, and a new generation of flexible conductive materials is widely researched. Among them, Ag nanowires have excellent bending resistance, high mechanical strength, good reliability, and excellent chemical stability, have been widely studied, and are considered as one of the most promising flexible conductive materials. In addition, the Ag nanowire plays an important role in biosensing, optical fibers and solar cells, and is one of the research hotspots in the field of the current nano materials.
There are many methods for preparing Ag nanowires, which can be mainly classified into physical methods, chemical methods, and the like according to their types, and the common methods include: template method, hydrothermal method, polyol method, self-assembly method, electrochemical method, and the like. However, most of the Ag nanowires prepared by the method are short, discontinuous and uncontrollable in orientation, and continuous and orderly-arranged Ag nanowire arrays cannot be prepared, which seriously limits the further application of the Ag nanowires in the fields of flexible electronic devices, optical fibers and the like.
The invention content is as follows:
the invention aims to provide a method for digitally and controllably printing Ag nanowires, aiming at the defects in the current Ag nanowire preparation technology. The method comprises the steps of dissolving polyvinylpyrrolidone, copper trifluoroacetate and silver trifluoroacetate by using N, N-dimethylformamide and tetrahydrofuran as a mixed solvent to obtain a precursor solution, printing an Ag nanowire array by using an electro-fluidic spray printing device, and finally annealing at high temperature to prepare the Ag nanowire array which is long and continuous, is uniformly arranged and is digitally controllable. The method solves the problems of short size and disorder in the traditional Ag nanowire preparation, can obtain the Ag nanowire array which is orderly arranged and digitally controllable, opens up a new path for the preparation of the Ag nanowire, and has important significance for further application of large-scale controllable integration of the Ag nanowire and the like.
The technical scheme of the invention is as follows:
a method of digitally controllable printing of Ag nanowires, the method comprising the steps of:
(1) mixing N, N-dimethylformamide and tetrahydrofuran to prepare a mixed solvent;
wherein, N-dimethylformamide: the mass ratio of tetrahydrofuran is 1-2: 1;
(2) dissolving polyvinylpyrrolidone, copper trifluoroacetate and silver trifluoroacetate in the prepared mixed solvent, stirring and dissolving for 1-24 hours at normal temperature to obtain a precursor solution;
wherein, the mass ratio is that silver trifluoroacetate: copper trifluoroacetate ═ 3-4:1, silver trifluoroacetate: 1-2:1 of polyvinylpyrrolidone, wherein the mass fraction of polyvinylpyrrolidone in the precursor solution is 7-15%;
(3) printing the precursor solution into a nanowire array by utilizing an electro-fluidic spray printing device;
the electrostatic spinning parameters of the process are as follows: the electrostatic spinning voltage is 1-1.5kV, the distance from the syringe needle to the substrate is 1-5mm, the liquid outlet quantity of the syringe needle is 1-100nL/min, and the substrate moving speed is 250-1000 mm/s;
(4) heating the nanowire array in a muffle furnace, calcining for 30-60 minutes at the temperature of 300-400 ℃, and cooling to obtain the Ag nanowire;
the Ag nanowire has the diameter of 700-5000nm, the length of 1 mm-20 cm and the interval of 100 mu m-1 cm.
The heating speed of the nanowire is 2-10 ℃/min, and the cooling speed is 2-10 ℃/min.
The essential characteristics of the invention are as follows:
the invention realizes the preparation of the long, straight and continuous Ag nano-wire with the centimeter grade by a digital controllable printing technology. In the prior art, methods such as a polyol method, a hydrothermal method, an autonomous loading method and the like are generally adopted for preparing the Ag nanowires, the length of the Ag nanowires prepared by the methods is hundreds of microns or even lower, and the Ag nanowires obtained by the traditional spinning technology for preparing the Ag nano materials are disordered.
According to the invention, through a large amount of researches, the Ag nano material is successfully prepared by printing under the low voltage of 1-1.5 kV. In the preparation process, the substrate for receiving the nanowires runs at the speed of 250-1000mm/s, and the originally bent and disordered nanowires are straightened through high-speed motion; meanwhile, polyvinylpyrrolidone with enhanced viscosity and a copper component with higher boiling point and low content are added into the precursor solution, so that the phenomena of breakage and agglomeration of the nanowires in the printing process and the calcining process are avoided.
The invention has the beneficial effects that:
the invention can regulate and control parameters such as the movement speed of the substrate, the distance between the syringe needle and the substrate and the like under a smaller spinning voltage, and prepare continuous and orderly Ag nanowires and arrays thereof. The energy consumption of the electrostatic spinning process is reduced, the safety is improved, the digital controllable printing of the Ag nano wires is realized, and the length and the orientation of the Ag nano wires and the distance between the wires can be adjusted. The problems of shortness and disorder in the current Ag nanowire preparation process are effectively solved, and a new idea is provided for the preparation of the Ag nanowire. The concrete expression is as follows:
1. the voltage for printing the silver nanowires is only 1kV, which is far less than the spinning voltage (20kV) in the silver nanowire preparation process in the prior art, so that the energy consumption is greatly reduced;
2. the invention can obtain long, straight and continuous silver nanowires, the length of which can reach 20cm without breaking and bending (the length of the Ag nanowire reaches the centimeter level can be seen by combining with figure 6), while the silver nanowires obtained by the current technology such as a hydrothermal method and a glycol method are short and about hundred microns level, while the reported silver nanowires in the traditional electrostatic spinning are disordered although the silver nanowires are long in length; (see comparison of FIGS. 1 and 4.)
3. The method can prepare the silver nanowire array, which is not available in other technologies and provides support for large-scale integration and array. (As can be seen by combining the representation of FIG. 2, the three silver nanowires are arranged regularly, long and continuous, and the array is successfully realized)
