SHORT DESCRIPTION Development of a graphene-polyurethane elastomer composite that is resistant to UVGI irradiation, enabling the sterilization and reuse of personal protective equipment (PPE).
BACKGROUND The COVID-19 pandemic highlighted the critical shortage of PPE and the need for materials that can withstand sterilization without degradation. This invention addresses the urgent need for durable, UVGI-resistant elastomeric materials for the effective long-term use and reusability of PPE, aiming to improve sustainability and reduce waste.
ABSTRACT This technology encompasses the integration of graphene into polyurethane elastomers to create a composite material that is resistant to UVGI sterilization, enhancing the durability and reusability of PPE such as masks and gloves. Employing a scalable and environmentally friendly process for graphene production, this composite demonstrates significant improvements in mechanical properties, including elasticity and toughness, which are maintained even after multiple sterilization cycles.
APPLICATIONS
PPE including masks and gloves
Medical equipment
Textiles
Reinforcement in cyclic wear, outdoor applications including the automotive industry
ADVANTAGES
Scalable and sustainable production of graphene/EC powders
Significant improvement in mechanical properties with low graphene/EC loading
Enhanced durability and reusability after UVGI sterilization
Overcomes commercialization barriers for graphene-polymer composites
