Development of new materials

In recent years, researchers have beenresistor pasteExtensive exploration has been conducted in the selection of materials. Traditional resistor pastes mainly use conductive materials such as carbon black and silver powder, but these materials have certain limitations in performance. In order to improve the performance of resistor paste, researchers have begun to focus on the development of new materials.

Graphene, as an emerging two-dimensional material, has attracted much attention due to its ultra-high conductivity and mechanical properties. The introduction of graphene not only improves the conductivity of the resistive paste, but also enhances its durability and stability. Research has shown that graphene films prepared by chemical vapor deposition (CVD) can significantly improve the performance of resistance slurries after appropriate treatment and dispersion.

Innovation in preparation process

The selection of process has a crucial impact on the performance of the final product in the preparation of resistance paste. Traditional preparation methods mainly include ball milling, sol - gel, etc., but these methods have some challenges in uniformity and stability.

The spray drying method is a new preparation process. By atomizing the slurry into tiny droplets and drying rapidly at high temperature, the powder with uniform particle size distribution and good fluidity can be obtained. This method not only improves the uniformity of the slurry, but also shortens the production cycle and reduces costs.

In addition, plasma treatment technology has also been applied in the preparation process of resistance slurries. Plasma treatment can change the chemical properties of the material surface, improve the dispersion and adhesion of the slurry, and thus improve the comprehensive performance of the resistance slurry.

Expansion of application fields

Flexible electronics is a rapidly developing field in recent years, with very high requirements for resistive pastes. Flexible electronics require stable resistance performance under bending, folding, and other conditions, which places higher demands on the flexibility and conductivity of the paste. By introducing high molecular weight polymers and nanomaterials, researchers have developed a series of high-performance resistive slurries suitable for flexible electronics.

Wearable devices are also one of the important application areas of resistive materials. Wearable devices require resistive paste to have good skin compatibility and comfort, as well as high conductivity and stability. Researchers have developed various resistive pastes suitable for wearable devices by optimizing formulas and processes, promoting the development of this field.
