Research on Creep Resistance of Flexible Pressure Sensor Based on Anhydride Curing Agent

In this article, the resistance value of the flexible pressure sensor was measured at the constant temperature and pressure, and combined with anhydride curing agent, a comparative experiment was carried out to investigate the effect of anhydride curing agent on the creep resistance of flexible pressure sensor. The result of experiment showed that the epoxy resin and the anhydride proceed the crosslinking reaction after the flexible pressure sensor was added to the anhydride curing agent. The network structure was formed, the volume of the polymer was reduced, the hardness was increased, and the resistance creep performance was increased. In addition, the result of creep test showed that the content of curing agent and curing temperature had a significant influence on the creep resistance of the sensor.
