HIGH-THERMAL RESISTIVITY AND ELECTRICAL CONDUCTIVITY COATING TECHNOLOGY

摘要

Electrically conductive polymers have attracted much interest in the last 20 years, largely because they simultaneously display the physical and chemical properties of organic polymers and the electrical characteristics of metals. Electrically conducting polymers have great potential to revolutionize a wide variety of fields. Conductive polymers are used in electronic packaging applications when constraints, such as process, temperature, stress levels, metallization options, contact pad pitch, or cost require an alternative to soldered interconnections. Numerous applications, including electrostatic materials, electromagnetic shielding, chemical/thermal/biochemical sensors, organic solar cells, and light- emitting diodes (LEDs) are some of the applications that will be greatly improved with conductive polymers. Recently, researchers from all over the world have investigated the electrical conductivity of composites that contain randomly dispersed conducting particles in an insulating polymer matrix. The introduction of electrically conductive fillers, such as graphite, carbon black, metal, and metal oxide powders into the polymeric matrix is a promising approach used to fabricate electrically conductive polymeric materials.
