Huake Chuangzhi nano silver wire technology has made another major breakthrough, and Wiley authoritatively released the first index
On May 26, 2022, under the leadership of CTO Zeng Xiping (Dr.), Huake Chuangzhi nanosilver technology made another major breakthrough, quaternary ammonium salt was introduced as a control agent into the nanosilver wire synthesis research, and the research results were authoritatively included by Wiley Online Library.
The title of this inaugural document is "Controllable synthesis of silver nanowires via an organic cation-mediated polyol method and their application as transparent electrode for touch screen", Controllable synthesis of nano-silver wire by organic cationic synergistic polyol method and its application as transparent electrode of touch screen".
In this literature, quaternary ammonium salts are introduced as an organic cation as a control agent to synthesize nanosilver wires. The experimental results show that the growth of nanosilver wires can be successfully controlled by using quaternary ammonium salt as a control agent, and the diameter of the prepared nanosilver wires ranges from 35.06 ~ 46.60nm, and it becomes smaller with the growth of carbon chains. Its synthetic nano-silver wire made of transparent electrode also shows good optical properties, with 95.6% transmittance at a low resistance value of 18Ω/square - the introduction of quaternary ammonium salt will have great development potential in the practical application of touch display.
As we all know, nanosilver is the best alternative material for ITO, and the controllable and macro preparation of nanosilver wire is the key to its development and application. At present, the synthesis method of mainstream nanosilver wire is polyol method, generally using PVP as a protective agent, chlorine/bromide ion as a control agent, and few literature studies and reveals the synthesis mechanism and controllable preparation method of nano-silver wire from the perspective of cations, especially organic cations. This study by Huake Chuangzhi starts from the perspective of cations.
By investigating the effects of different inorganic and organic cations on silver wire synthesis, the growth law of nano-silver wire was revealed, and the length and diameter of nano-silver wire were further regulated.
In the field of nanosilver research and development, Huake Chuangzhi has always been at the forefront of the industry: in the era of polyol preparation, it took the lead in studying the effect of surfactants on the growth mechanism of nanosilver wire; Not long ago, the biomass hydrothermal method for synthesizing nano-silver wire was successfully developed, opening up a new track for nano-silver preparation; From the perspective of cations, this first publication of the literature to study and reveal the synthesis mechanism and controllable preparation method of nanosilver wire, which provides strong technical guidance for the production of controllable macro and provides new ideas and reference directions for the controllable preparation of nanosilver wire! Huake Chuangzhi may also be about to usher in another breakthrough in the performance of nanosilver!
