Novel functional polymer/YBCO superconductor ceramic composites for thermistor, electromagnetic shielding effectiveness and electrostatic charge dissipation

摘要

The electromagnetic radiation is harmful to a man when its density is more than a certain value. It is very important to develop a new type of conductive polymer composites in order to prevent men from radiation. This paper presents the relationship between conductivity, shielding effectiveness (EMI) and electrostatic charge (ESD) of rubber filled with different contents of YBCO superconductor. The results showed that the good property of material, positive temperature coefficient of resistivity (PTC), temperature sensor and ESD applications. Furthermore, the shielding effect of the novel conductive composite to EMI and microwave radiation is well.
