    Definition and history. Fitted with a quick-release locking mechanism, an autoclave (Latin for “self-locking”) is a pressure vessel used for sterilizing instruments, liquids and other utensils. The contents of an autoclave are subjected to high pressure and heated with steam to temperatures of 121 degrees Celsius or higher for a defined period of time depending on the size and type of the materials involved.

    PEI is a high-performance polymer with a high Tg (215°C), excellent flame retardancy, low smoke generation, and good mechanical properties [128]. The melting temperature of PEI is as high as 340–360°C. Therefore, a water vapor–induced phase separation process was applied to prepare microcellular PEI/graphene composite foams.
