Method & Evidence

AimTo investigate the impact of graphene addition on the thermal and mechanical properties of polyurethane-coated meta-aramid fabrics for personal protective equipment.

MethodExperimental analysis

ProcedurePolyurethane coatings were modified with varying weight percentages of graphene (0.25% and 0.5%). These modified coatings were then applied to a meta-aramid fabric. The thermal stability of the coated materials was assessed using thermogravimetric analysis, and mechanical properties, specifically tear resistance, were evaluated. The results were compared against performance requirements for firefighter protective clothing.
