Nanostructured poly(benzimidazole) membranes by N-alkylation

eXPRESS Polymer Letters, 2014
Modification of poly(benzimidazole) (PBI) by N-alkylation leads to polymers capable of undergoing microphase separation. Polymers with different amounts of C18 alkyl chains have been prepared. The polymers were analyzed by spectroscopy, thermal analysis,

Green Synthesized Composite AB-Polybenzimidazole/TiO₂ Membranes with Photocatalytic and Antibacterial Activity

Crystals
Novel AB-Polybenzimidazole (AB-PBI)/TiO2 nanocomposite membranes have been prepared using a synthetic green chemistry approach. Modified Eaton’s reagent (methansulfonic acid/P2O5) was used as both reaction media for microwave-assisted synthesis of AB-PBI

Polybenzimidazole (PBI) fibers

, 2014
Polybenzimidazole (PBI) fibers are produced from polybenzimidazole polymer which has a high thermal and chemical strength with a long chain aromatic structure. These fibers are first used in protective technical textile products due to their good moisture regain and textile performance properties like good hand and drape.
