Problems solved by technology

However, this type of sensor mostly uses traditional linear polymer electrolytes as sensitive materials, which are prone to slip and loss in high-humidity environments. As the humidity increases, the polymer materials will absorb moisture and expand, resulting in their high-humidity resistance and long-term Poor stability hinders its further popularization and application to a certain extent

Description

technical field [0001] The invention relates to a polymer material, in particular to a polymer material with humidity sensitive resistance properties and a preparation method thereof. Background technique [0002] Currently commercialized humidity sensors mainly include inorganic ceramic semiconductor type and organic polymer type. The polymer humidity sensor has become the mainstream of the humidity sensor because of its good response characteristics, wide measurement range, good stability, room temperature detection, easy integration, miniaturized mass production, and low price. Among them, the polymer resistive humidity sensor is very simple to prepare, has good performance, and is easy to integrate into the system to realize the measurement and control of humidity. It is one of the research and development of humidity sensors. However, this type of sensor mostly uses traditional linear polymer electrolytes as sensitive materials, which are prone to slip and loss in high...
