Modern Materials

  12-1 Recount the ways in which a liquid crystalline phase differs
from ordinary (isotropic) liquid phase.
  12-2

Distinguish among the major classes of liquid- crystalline
phases.

 

12-3 Describe what is meant by the terms monomer and polymer,
and give some examples.
  12-4 Explain how a polymer is formed from monomers via
(a) addition polymerization or (b) condensation
polymerization.
  12-5 Describe how liquid-crystalline materials are employed
in liquid crystal displays for electronics equipment.
  12-6 Explain how processing affects the properties of synthetic
polymer fibers and how it relates to molecular orientations
in the fiber.
  12-7  Explain what is meant by the term "crystallinity" in polymers,
and indicate how polymer properties generally vary with
degree of crystallinity.
12-8 Describe the process of crosslinking in polymers, and explain
how it affects polymer properties.
12-9 Describe the vulcanization of rubber and its effect on the
properties of the material.
  12-10 Define the term "ceramic" and give several examples of
ceramic materials.
  12-11 Indicate the advantages and disadvantages of engineering
ceramic as compared with other materials in various
applications.
  12-12 Describe the sol-gel process for forming ceramic materials.
  12-13 Give examples of ceramic composites and indicate their
potentialadvantages over noncomposite ceramic materials.
  12-14 Define the term superconductivity and give an example of a
super conducting ceramic oxide.
  12-15 Explain what is meant by the term "thin film" and provide
several illustrations of applications of thin films.
  12-16 Explain how thin films are formed via vacuum deposition,
sputtering, and chemical vapor deposition.
