Mechanical Properties of Carbon Nanofiber-Reinforced PBI Composites
1 Introduction Polybenzimidazole (PBI) commercialized by the Celanese Corporation in 1983 is an aromatic heterocyclic polymer that is resistant to strong acids,bases,and high temperatures1.PBI fibers are widely used in firefighter protective clothing,high-temperature gloves,and astronaut flight suits due to its excellent thermal and chemical stability2.Recently,phosphoric acid doped PBI membrane has emerged as a promising candidate for polymer electrolyte in high temperature proton exchange membrane fuel cell (PEMFC)3,4.Because of excellent film forming capability,PBI has been used as coating material since the 1990s5,6.Development of thchnologies leads unavoidably to increasingly large demands on PBI materials with higher mechanical performance.It is well known that the mechanical performance of polymer materials can be effectively improved by introducing a suitable amount of inorganic reinforcement such as carbon nanofiber to form composite materials7,8.Therefore,research on the preparation and mechanical properties of PBI nanocomposites is of great importance.
