Abstract To synthesize colorless superheat‐resistant polyimide films, one of the valid approaches is incorporation asymmetric and warped structures in main chain. Applying this approach on 5(6)‐amino‐2‐(4‐aminobenzene)benzimidazole (PABZ) changing its linearity, 6, 5′‐diamine‐2′‐methyl‐1‐methyl‐2‐phenylbenzimidazole (5a) 3′‐diamine‐2′‐methyl‐1‐methyl‐2‐phenylbenzimidazole (5b) were devised synthesized successfully, then polymerized with 1,2,4,5‐cyclohexanetetracarboxylic dianhydride (HPMDA)....
Abstract To make the colorless polyimides (CPIs) suitable for application of flexible display technology, polyimide (PI) films need to have both good optical properties and thermal properties. get wanted properties, 2‐(2‐methyl‐4‐(2‐methyl‐4‐aminobenzamido)phenyl)‐5‐(2‐methyl‐4‐aminobenzamido)‐ N ‐phenylbenzimidazol (5a) 2‐(2‐methyl‐4‐(2‐trifluoromethyl‐4‐aminobenzamido)phenyl)‐5‐(2‐trifluoromethyl‐4‐aminobenzamido)‐ (5b) were synthesized, which contained benzimidazole bis‐amide structures....
Membrane fouling is a key challenge in the process of utilizing polyphenylene sulfone(PPSU) ultrafiltration (UF) membranes. To address this issue, an amino-functionalized poly(ionic liquid), poly(1-vinyl-3-propylamine imidazolium bis(trifluoromethane sulfonyl) imide) (PIL[TFSI]), was synthesized via free radical polymerization and incorporated into prepared UF membranes-based PPSU with nanochannels through nonsolvent induced phase separation method. 1H NMR, ATR-FTIR, XPS EDS spectra verified...
Abstract Polyimides (PIs) with super heat‐resistance and ultralow coefficient of thermal expansion (CTE) are required urgently to employ as plastic substrates in flexible‐display devices. To attain the target properties, we designed synthesized a novel bibenzimidazole diamine characterized having N ‐phenyl group, namely 1‐phenyl‐2,2′‐bibenzoimidazole‐5,5′‐diamine (PhDABZ), focused on an aromatic poly(benzimidazole imide) series derived from 1,2,4,5‐benzenetetracarboxylic (PMDA)....
A novel tight-ultrafiltration (t-UF) antifouling membrane employed for dye/salt separation is fabricated through the co-deposition of dopamine and zwitterionic copolymer Poly(2-aminoethyl methacrylate-Ethyl acrylate-sulfopropyl piperidine salt) [P(AE-EA)] onto polyphenylene sulfone (PPSU) substrate. The polydopamine (PDA) P(AE-EA) are connected by covalent bond formed via Michael addition Schiff base reactions. composition characteristics surface investigated using scanning electron...
