“…These polymers actually showed excellent fiber‐forming abilities and high mechanical and thermal resistance. Poly(benzimidazole‐imide)s were also reported as early as 1967,11 and some other papers on this class of polymers have appeared during the last two decades 12, 13…”

“…Because of these unique properties, PBI are widely applied to fire-resistant protective gears, firemen's turnout coats, astronaut's space suits, industrial workers' suits, and circuit boards [21]. Although PBIs suffer the low processability which may diminishes their applications, but it may be improved through several structural modifications such as the incorporation of flexible bridging linkages and the introduction of bulky substituents as pendent groups along with the rigid polymer backbone [22][23][24][25][26][27]. In order to improve thermal and mechanical properties of PBI, several kinds of inorganic fillers such as silica [28,29], clay [30,31], ZnO [32], graphene oxide (GO) [33], carbon nanotube (CNT) [34,35], and polyhedral oligomeric silsesquioxane (POSS) [36] have been incorporated into the PBI matrix.…”

In the present study, novel poly(benzimidazole-amide)/titania (PBIA/TiO 2 ) nanocomposites containing phthalimide and benzimidazole pendent groups with different amounts of modified titania nanoparticles (TiO 2 NPs) were successfully fabricated through ultrasonic irradiation technique. Due to the high surface energy and tendency for agglomeration, the surface TiO 2 NPs was modified by a coupling agent as (3-methacryloxypropyl)trimethoxysilane (MPS) to form MPS-TiO 2 nanoparticles. FTIR spectroscopy confirmed that MPS was successfully grafted onto the TiO 2 nanoparticles surface through Ti-O-Si chemical bonds. Thermogravimetric analysis (TGA) revealed a surface coverage of the coupling molecule of 2.8 wt.%. The resulting nanocomposites were fully characterized by FTIR spectra, X-ray diffraction (XRD) patterns, scanning electron microscopy (SEM), and TGA. SEM analyses of nanocomposites were performed in order to investigate the dispersion of nanofillers in the PBIA matrix. The TGA results of PBIA/TiO 2 nanocomposites showed that the thermal stability is obviously improved the presence of MPS-TiO 2 NPs in comparison with the pure PBIA and that this increase is higher when the NP content increases.

“…Despite their extensive use, most of the aromatic PBIs have high melting point temperatures and poor solubility in conventional organic solvents due to their highly rigid backbones and strong intra‐interchain hydrogen bonding interactions may restrict their potential applications in some fields . To overcome these limitations, much of research efforts have been focused on the modification of PBI properties by incorporating flexibilizing groups or other bulky units in main or side chain to enhance the solubility and therefore make such polymers more easily processable . One of the simplest approaches to improve both the solubility and processability of PBI polymers is the structure modification by copolymerizing their monomers.…”

Fabrication, characterization, and properties of novel poly(benzimidazole‐amide)/functionalized ZnO nanocomposites (PBIA/APS‐ZnO NCs) were investigated. At first, an aromatic PBA containing 3 imidazole units per repeat unit was synthesized by direct polycondensation of 1,3‐bis(5‐carboxylic acid‐2‐benzimidazole)benzene (BCAB) with 5‐(2‐benzimidazole)‐1,3‐phenylenediamine (DAMI) with good yield as a polymeric matrix. The periphery of zinc oxide nanoparticles (ZnO NPs) was modified with 3‐aminopropyltriethoxysilane (APS) to have a better dispersion NPs and enhancing interactions between nanoparticles and PBIA matrix. Different percentages of functionalized NPs (0, 4, 8, and 12 wt.%) were then embedded in PBA matrix through ultrasonic irradiation technique. Fourier transform infrared and thermo‐gravimetric analysis (TGA) confirmed that APS was successfully attached on the ZnO NP surface. The obtained NCs were characterized by means of Fourier transform infrared, X‐ray diffraction, scanning electron microscopy, and TGA. The TGA of the PBIA/APS‐ZnO NCs showed the enhancement in the thermal stability in comparison with the neat PBIA and that this increase is higher when the NP content increases. Scanning electron microscopy analyses of NCs revealed that the dispersion of APS‐ZnO NPs was uniformly done in the PBIA matrix.
