  • Method of preparing thin film polymeric gel electrolytes
    Patent number: 5691080
    Abstract: Novel hybrid thin film electrolyte, based on an organonitrile solvent system, which are compositionally stable, environmentally safe, can be produced efficiently in large quantity and which, because of their high conductivities .apprxeq.10.sup.-3 .OMEGA..sup.-1 cm.sup.-1 are useful as electrolytes for rechargeable lithium batteries.
    Type: Grant
    Filed: July 16, 1996
    Date of Patent: November 25, 1997
    Assignee: Sandia Corporation
    Inventors: Dora K. Derzon, Charles Arnold, Jr.

  • Method of preparation of removable syntactic foam
    Patent number: 5432205
    Abstract: Easily removable, environmentally safe, low-density, syntactic foams are disclosed which are prepared by mixing insoluble microballoons with a solution of water and/or alcohol-soluble polymer to produce a pourable slurry, optionally vacuum filtering the slurry in varying degrees to remove unwanted solvent and solute polymer, and drying to remove residual solvent. The properties of the foams can be controlled by the concentration and physical properties of the polymer, and by the size and properties of the microballoons. The suggested solute polymers are non-toxic and soluble in environmentally safe solvents such as water or low-molecular weight alcohols.
