A transmission electron microscope for use in investigations of               complex fluid and polymer systems will be acquired.  Novel                      freeze-fracture techniques used will directly examine                           polyacrylamide gels, rod-coil transitions of polydiacetylene                    solutions, and surfactant-oil-water microemulsions using electron               microscopy.  Rapid freezing of these systems can preserve the                   microstructure without artifact. The solidified fluid is                        fractured and coated with layers of platinum and carbon to                      replicate the fracture surfaces. These replicas are then examined               in the electron microscope with molecular resolution.  The                      replicas can also be examined with the scanning tunneling                       microscope to assess three dimensional contours with high                       resolu1tion.  Individual polymer chains can be visualized with                  unprecedented resolution and the distribution of interstitial                   fluid in gels can be measured.  For the first time, direct                      feedback about the influence of external perturbations on the gel               structure is possible.  The three dimensional structure of mid-                 range microemulsions consisting of equal volumes of oil and water               cosolubilized by surfactant can also be examined with molecular                 resolution.  Solution cast films of conducting polymer                          composites can be examined to determine the nature of the                       composite and the morphology of the conducting fraction.                        Biological and other non-conducting materials can be imaged                     simultaneously with scanning tunneling and transmission electron                microscopy.
