  • Phase-inversion polymer composite material, fabricating methods and applications of same
    Patent number: 11932752
    Abstract: A composite film usable as a separator of an electrochemical device includes hBN nanosheets and at least one polymer. The hBN nanosheets are uniformly dispersed within a matrix of said least one polymer to achieve a highly porous microstructure. Said at least one polymer comprises one or more electrically insulating and electrochemically inert polymers.
    Type: Grant

  • STERILIZABLE AND REUSABLE ULTRAVIOLET-RESISTANT ELASTOMER COMPOSITES, FABRICATING METHODS, AND APPLICATIONS OF SAME
    Publication number: 20240052134
    Abstract: The invention relates to a sterilizable and reusable ultraviolet-resistant elastomer composites including an elastomeric matrix comprising at least one elastomer; and an UV-resistant additive incorporated into the elastomeric matrix. The ultraviolet-resistant elastomer composite remains mechanically robust over at least 150 sterilization cycles, enabling safe reuse following ultraviolet germicidal irradiation (UVGI). Beyond N95 masks, these UVGI-compatible ultraviolet-resistant elastomer composites have potential utility in other PPE applications to address the broader issue of single-use waste.

  • TWO-DIMENSIONAL INSULATOR BASED PRINTABLE ION-CONDUCTIVE AND VISCOSITY-TUNABLE INKS, FABRICATING METHODS AND APPLICATIONS OF SAME
    Publication number: 20220145104
    Abstract: The invention relates to printable ion-conductive and viscosity-tunable inks based on two-dimensional (2D) insulators, forming methods and applications of the inks. The 2D insulating material based printable ink includes at least one solvent; and an exfoliated composition dispersed in the at least one solvent. The exfoliated composition includes a 2D insulating material and a dispersant and stabilizing agent. The printed structures of the 2D insulating material based printable ink possess high ionic conductivity, chemical and thermal stability, and electrically insulating character, which are an ideal set of characteristics for printable battery components such as separators and solid electrolytes.
