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.
