  • Method to produce colorless, high porosity, transparent polymer aerogels
    Patent number: 10836855
    Abstract: A method to produce a polymer gel includes dissolving precursors in a solvent to form a precursor solution, the precursors including polymer precursors, a stable free radical, one or more initiating radicals, and one or more stable free radical control agents, and heating the precursor solution to a temperature of polymerization to produce a cross-linked gel. A dried polymer aerogel has a Brunauer-Emmett Teller (BET) surface area over 100 m2/g, porosity of greater than 10%, visible transparency greater than 20%, color rendering index of over 20%, and average pore size of less than 100 nm.

  • ELECTROSTATIC DISCHARGE PROTECTION SHIELD DEVICE
    Publication number: 20040132325
    Abstract: An electrostatic discharge protection shield device, which may be used in bases or cradles for mobile electronic apparatus, among other uses. A grounded electrostatic discharge shield is movable between two positions, one which precludes contact with data/dc power contacts of a data/dc power connection and another, in which the contacts are exposed for normal operation in connection with the parent electronic apparatus.
