A multifunctional polyurethane sponge based on functionalized graphene oxide and carbon nanotubes for highly sensitive and super durable fire alarming

The lightweight materials with good flame retardancy and early fire alarming function can play an effective role in reducing the potential loss caused by fire disasters, which will be highly demanded in the interior decoration of automobile and house. Herein, a multifunctional polyurethane sponge (PUS) was prepared by depositing the flame retardant-modified graphene oxide (FGO) and chitosan-functionalized carbon nanotubes (CNTs) through the...
