PBI (polybenzimidazole) is a thermally stable high performace polymer. In a variety of forms, e.g. fibers, neat resin and composites, PBI finds use in a wide range of high temperature applications. The synthesis of PBI, and properties, and applications of fiber and molded resin are discussed. Also included are recent developments in composite fabrication technology and PBI composite applications in carbonlcarbon composites.

PEDOT:PSS-Coated Polybenzimidazole Electroconductive Nanofibers for Biomedical Applications
TLDR
These findings highlight the great potential of PEDOT:PSS-coated PBI electrospun scaffolds for a wide variety of biomedical applications, including their use as reliable in vitro models to study pathologies and the development of strategies for the regeneration of electroactive tissues or in the design of new electrodes for in vivo electrical stimulation protocols.
Outgassing behavior of different high-temperature resistant polymers
In vacuum applications, polymers often need to be used in spite of their relatively high outgassing rates, e.g., as sealing or spacer material. For some polymers—like Viton®, which is used for
Fiber Selection for Reinforced Additive Manufacturing
The purpose of this review is to survey, categorize, and compare the mechanical and thermal characteristics of fibers in order to assist designers with the selection of fibers for inclusion as
Novel homo- and co-poly(p-phenyene ether sulfone benzimidazole/sulfide sulfone benzimidazole)s: synthesis and properties
The homo- and co-poly(p-phenyene ether sulfone benzimidazole/sulfide sulfone benzimidazole)s (PESI/PPSSI) had been prepared by solution polycondensation of the mixtures of 4,4′-dicarboxydiphenyl
Carbonized Electrospun Nanofiber Sheets for Thermophones.
TLDR
Thermoacoustic performance of thin freestanding sheets of carbonized poly(acrylonitrile) and polybenzimidazole nanofibers are studied as promising candidates for thermophones and applications of thermoac acoustic projectors for loudspeakers, high power SONAR arrays, and sound cancellation are discussed.
Polybenzimidazole nano fi bers for neural stem cell culture
TLDR
This novel study assessed the biocompatibility of polybenzimidazole (PBI) as electrospun fibers and after being doped with different acids to find a promising PBI fibrous scaffold material to be used in neural cell engineering applications.
