  • ROOM TEMPERATURE THREE DIMENSIONAL PRINTING OF A SUPER-SOFT AND SOLVENT FREE ELASTOMER
    Publication number: 20230348649
    Abstract: A composition of matter including a yield stress fluid including self-assembled copolymers each including at least one first type of polymer covalently bonded to at least one second type of polymer, wherein the first type of polymer (“first block”) is microphase separated from the second type of polymer (“second block”), at least one of the first block or the second block has its glass transition temperature less than or equal to 20° C., and the yield stress fluid has a critical yield stress at room temperature or below room temperature, without addition of a solvent for the first block or the second block. Examples of the self-assembled copolymers include a diblock copolymer or bottlebrush copolymer including the first block covalently bonded to the second block.

  • Capacitive pressure sensor with bottlebrush elastomer dielectric layer for low pressure sensing
    Patent number: 11780969
    Abstract: A composition of matter including a crosslinked bottlebrush polymer, wherein the crosslinker units in the composition of matter are soluble with the bottlebrush polymer. In one example, the crosslinked bottlebrush polymer is tailored as a single phase (solvent free) elastomer useful in a capacitive pressure sensing device. A novel embodiment of the present invention further includes demonstration of a universal approach to form solvent-free bottlebrush polymer networks by photo-crosslinking mixtures of well-defined bottlebrush precursors and bis-benzophenone-based additives. This method has been proven effective with a wide variety of different side-chain chemistries.
