由2,2-bis(4-(2-(5-aminobenzimidazoly))phenyl)propane
(Bis/IM/NH2)、1-(4-aminophenoxy)-4-(4-aminophenyl)-2,6-di-tert-butyl-benzene
(p/DTBP/NH2)、m-tolidine (DMB)二胺單體與六環酸酐1,4,5,8-Naphthalenetetracarboxylic dianhydride (NTDA)合成含Benzimidazole側基之聚醯亞胺共聚物(PI),其固有黏度範圍介於1.13〜1.40 dL/g之間。再將isophthalic acid (m-COOH)與3,3'-diaminobenzidine (DAB)合成聚苯並咪唑(m-PBI),其固有黏度為1.25 dL/g。再將聚醯亞胺共聚物及聚苯並咪唑摻混作為質子傳導膜,這些摻混物均能塗佈成具有韌性的薄膜。這些膜具有良好的熱安定性,在氮氣及空氣的條件下10 %裂解的溫度都高於450 °C。未摻雜磷酸前它們的抗張強度皆大於97 MPa;然而,在摻雜磷酸之後,因膨潤使分子間作用力降低,因而抗張強度大幅下降。本研究藉由側甲基進行交聯反應,交聯後摻混薄膜因受交聯鍵結,造成分子鏈較緊密堆積,導致磷酸摻雜量減少,但仍能有足夠高的質子傳導度,並能維持好的機械性質,例如交聯後C15-PI6(Bis6DTBP2.5DMB1.5)PBI4濕膜的抗張強度由原本的10.3 MPa增加至13.9 MPa。 在質子傳導度方面,摻混薄膜PI4PBI6、PI5PBI5與PI6PBI4,在160°C時,它們的質子傳導度皆比m-PBI大,例如PI6PBI4及PI5PBI5,摻混薄膜在160°C時的質子傳導度分別為61.8 mS/cm與54 mS/cm,皆大於m-PBI的質子傳導度(43.1 mS/cm)。這結果顯示摻混含有Benzimidazole側基之PI的摻混薄膜,比起只有主鏈含Benzimidazole之m-PBI更容易傳導質子。這些結果顯示摻混薄膜有潛力應用於中溫型質子傳導薄膜。
A series of polyimides(PIs) were synthesized from 2,2-bis(4-(2-(5-aminobenzimidazoly))phenyl)propane (Bis/IM/NH2), 1-(4-aminophenoxy)-4-(4-aminophenyl)-2,6-di-tert-butyl-benzene (p/DTBP/NH2), m-tolidine (DMB) diamine and 1,4,5,8-Naphthalenetetracarboxylic dianhydride( NTDA). The PIs had inherent viscosities of 1.13〜1.40 dL/g. The blended polymers were prepared from the PIs and m-PBI. The blended polymers formed tough and transparent films. The blended polymers exhibited high thermal stability with 10%decomposition temperature more than 450°C. These films exhibited good mechanical properties with tensile stress exceeded 97 MPa. However, the mechanical properties of the blended polymers significantly decreased when phosphoric acid doping level increased. The mechancial properties of phosphoric acid doped blended polymers could be improved via crosslinking reaction of methyl group, crosslinked blended polymers would form close packing, and it led to decrease of phophoric acid doping level, but it could still maintain high mechanical properties. For example, the tensile strength of cross-linked C15-PI6(Bis6DTBP2.5DMB1.5)PBI4 in wet state enhanced from 10.3 to 13.9 MPa after crosslinking reaction. The blended polymers of PI4PBI6, PI5PBI5, and PI6PBI4 exhibited higher on proton conductivites at 160°C than m-PBI(43.1mS/cm). For example, the proton conductivities of PI6PBI4 and PI5PBI5 were 61.8 and 54 mS/cm, respectively. Thus, these blended polymers containing benzimidazole on main chain and on pendant could be the promising materials alternative to m-PBI membrane for medium temperature fuel cells applications because of their high proton conductivity and good oxidative stability
