Abstract

Metal/polymer composites are evident in sub-micron electronic components. Though they do not have the structural visibility of composites of metals and polymers described in the two previous chapters, they are major factors in the economy of the United States. For example, virtually all magnetic recording media now in use consists of magnetizable particles dispersed in an organic polymer. The total United States market for magnetic particles in 1985 was approximately $285 million, and the market for tapes and disks was $8 billion. There are many developments taking place for which theoretical analyses are incomplete, as will be observed in this chapter. The physical and electrical properties of materials developed at a macro-level are not always applicable at sub-micron dimensions. The interactions of energy levels of unpaired electrons, the influence of the broad spectrum of radiation, and hostile environments become the focus of attention at sub-micron distances. Semiconductors, magnetic devices, storage batteries, and capacitors are, in many instances, examples of micro-metal/polymer composites. Magnetic recording devices and magnetic components comprise important segments of the electronic industry and will be examined in this chapter. The roles of polymer enamels used with magnetic wires will be summarized. Chapter 9 will concentrate upon the semiconductor devices and energy storage accessories.
