Study on preparation and analytical engineering theory of nanocomposites based on conductive polymer

This experiment aims to study the electrochemical properties of polypyrrole and γ-ferric oxide complex, through the cyclic voltammetry, UV spectrophotometry, infrared spectrophotometer, and other electrochemical characterization instruments to understand the performance of the complex formed under different conditions. By comparing the performance of composite products under different conditions, we can find alternative or manufacture new battery or capacitor materials. 1. Traditional batteries At present, mobile electronic devices are the forefront of application technology. However, with the rapid development of hardware and software of mobile devices, as well as the industrialization of electric vehicles, the disadvantages of traditional batteries have gradually emerged.The battery is designed to be smaller and have greater storage capacity, meaning that a smaller size can store more power.The more important point is that it has a more stable and secure nature.Existing battery improvements are mainly in the structure of the improvement.Common lead batteries are large, thick, cheap and easy to manufacture, making them widely available in the low-end electric car market.However, due to the increase of battery use time, unreasonable use, the crystal in the battery punctures the battery structure and forms an internal short circuit, which is easy to cause battery explosion or other problems during use (charging or discharging process). 2. The strategic significance of battery industry From the perspective of environmental status, traditional fossil energy vehicles rely on non-renewable fossil energy - petroleum. Fossil energy is produced by natural activities, and the time dimension is too long to make up for the huge consumption of human beings today. And using fossil fuels produces large amounts of carbon dioxide, a greenhouse gas. However, under the political environment, the US dollar settlement system makes China's oil import under the control of the US. Since China's reform and opening up, the automobile industry has been the key development industry in China, and the control of the US on oil has affected China's economic development. The research on new batteries is of great strategic importance, both environmentally and politically.Only new types of batteries that are safe, efficient and capable of storing enough energy can effectively win market share and replace petroleum energy completely. 3. Conductive polymer research Conductive polymer is also known as conductive polymer. The polymer synthesized in a certain way has excellent conductivity, because the large conjugated Π system formed by the conductive polymer allows electrons to move freely on this system, thus conducting electricity. Pure polypyrrole has poor electrical conductivity, because the polymer band gap is large, the free movement of electrons is blocked, and the performance is poor electrical conductivity. Different types of doping produce polypyrrole with different electrical conductivity and morphology
