Aromatic Polysulfones Used in Sensor Applications

摘要

Aromatic poly(ether sulfone)s are a family of amorphous thermoplastics that possess unique high performance properties as engineering materials: high strength, the highest service temperature of all melt-processable thermoplastics, low creep, good electrical characteristics, transparency, self-extinguishing properties and resistance to greases, many solvents and chemicals. They may be processed by extrusion and injection molding. Since the chemical and physical properties of polymers may be tailored by the chemist for particular needs, they gained importance in the construction of sensor devices. The knowledge of new materials, such as polysulfone allows to expand the possibilities of constructing potentiometric and amperometric sensors. Recently polysulfones have been used in the fabrication of sensors in various fields such as: humidity sensor, gas sensors, biosensors, immobilization of enzyme, enzyme membrane reactor, etc.
