It is well known that polymeric and composite materials are finding various applications in some critical areas of human endeavors, such as medicine, medical appliances, energy and the environment. This edition will, hopefully, evoke interest from scientists working in the fields of chemistry, polymer chemistry, electrochemistry and material science. Its applications and uses include: polymer electrolyte membrane fuel cells, sensors, actuators, coatings, electrochromic and electroluminescent materials, magnetic polymers, organo-metallic polymers, tissue engineering, methods of the immobilization of biological molecules, and dental and orthopedic applications. This edition is a highly valuable source for scientists, researchers, upper-level undergraduate and graduate students, as well as college and university professors, because it provides the most up-to-date reference work summarizing the pioneering research work in the field of polymeric and composite materials.
