Electrolysis of Water and Fuel Cell Coating 1. Electrolysis of Water Coating The importance of electrode material spraying: In the process of electrolysis of water, the performance of the electrode plays a key role in the efficiency of electrolysis. By spraying the catalyst on the surface of the electrode, the reaction activity of the electrode can be greatly improved. For example, for hydrogen evolution reaction (HER) and oxygen [...]
Applications of Photosensitive Polyimide Photosensitive polyimide (PSPI) is a type of polymer material that has both heat resistance and photosensitive properties. It is a very important semiconductor material and a very stuck material. Due to its electrical insulating properties, it protects semiconductor circuits from physical and chemical conditions. Photosensitive polyimide mainly plays two major roles in the electronic field: photoresist and electronic packaging. 1. As photoresist As a [...]
Classification of Photosensitive Polyimide Classification of Photosensitive Polyimide - Photoresist & Polyimide Films Coating Systems - Cheersonic According to the different photolithography patterns, photosensitive polyimide (PSPI) can be divided into positive photosensitive polyimide (p-PSPI) and negative photosensitive polyimide (n-PSPI). Positive PSPI is that the ultraviolet irradiation area dissolves in the developer, and negative PSPI is that the irradiation area is cross-linked and solidified and no longer dissolves in [...]
Advantages of Ultrasonic Spray Pyrolysis of Perovskite Ultrasonic spray pyrolysis of perovskite has the following advantages: 1. High film quality Good uniformity: Spray pyrolysis can evenly disperse the precursor solution into tiny droplets, and the thin film formed by these droplets on the substrate has a high degree of uniformity. Compared with some traditional preparation methods, such as spin coating, which may cause uneven film thickness due to [...]
Difficulties of Photosensitive Polyimide The production of PSPI photoresist is in the middle of the industrial chain structure. It is an ideal insulating material in the field of electronics and microelectronics. It is one of the most important electronic chemical materials in the fields of optoelectronics and microelectronics such as display panels, LED packaging, semiconductors, etc. It is widely used as interlayer insulation, surface passivation, stress buffering, and [...]
The Difference Between Energy Storage Batteries and Power Batteries At present, energy storage batteries generally refer to lithium-ion energy storage batteries. Of course, due to the particularity of energy storage batteries, they are different from power batteries in many aspects, mainly including the following points: 1. Different application scenarios • Energy storage batteries: small household energy storage and large base station energy storage. Large base station energy storage [...]
Advantages of Guidewire Spray Medical Coating As an auxiliary tool in medical surgery, guide wires play an important role in the fields of vascular interventional therapy, endoscopic surgery, neurointerventional therapy and other fields. In order to improve the performance and safety of guide wires, coatings with specific functions are often sprayed on the surface of guide wires in the medical field. The benefits of spraying medical coatings on [...]
Application of Thermally Conductive Insulating PI Film In the era of highly thin, multifunctional and integrated electronic devices, it will inevitably lead to heat accumulation inside the composite material, seriously affecting the stable operation and service life of the equipment. How to achieve fast and efficient thermal conductivity and heat dissipation of dielectric materials has become a key issue affecting the development of electronic equipment. The low intrinsic [...]
Spray Pyrolysis Powder Making 1. The role of nitrogen as a guide gas Protective role: In the spray pyrolysis process, nitrogen as a guide gas mainly plays a protective role. Since many metal compounds are easily oxidized with oxygen in the air at high temperatures, nitrogen can create a relatively inert atmosphere to prevent the metal ions in the precursor solution from being over-oxidized. For example, when preparing [...]
Ultrasonic Coating of Electrocatalyst on Membrane for Electrolysers The ultrasonic coating technology has emerged as a crucial and highly effective method for the deposition of electrocatalyst on membrane or electrodes specifically designed for electrolysers. Ultrasonic coating offers a unique and precise approach to uniformly distribute the electrocatalyst material. Through the utilization of ultrasonic waves, the electrocatalyst particles can be dispersed and propelled onto the surface of the membrane [...]
