Description
イオン伝導性測定:自作測定用プローブ(ポリテトラフルオロエチレン製)上で短冊状膜試料の表面に白金線(直径:0.2mm)を押しあて、80℃95%RHの恒温・恒湿オーブン(株式会社ナガノ科学機械製作所、LH−20−01)中に試料を保持し、白金線間のインピーダンスをSOLARTRON社1250FREQUENCY RESPONSE ANALYSERにより測定した。極間距離を変化させて測定し、極間距離とC−Cプロットから見積もられる抵抗測定値をプロットした勾配から以下の式により膜と白金線間の接触抵抗をキャンセルした導電率を算出した。
導電率[S/cm]=1/膜幅[cm]x膜厚[cm]x抵抗極間勾配[Ω/cm]
メタノール透過速度:イオン交換膜の液体燃料透過速度はメタノールの透過速度として、以下の方法で測定した。25℃に調整した5M(モル/リットル)のメタノール水溶液に24時間浸漬した平均厚み50μmのイオン交換膜(平均厚みが48μmから52μmの範囲に入っているものを平均厚み50μmの膜とする)をH型セルに挟み込み、セルの片側に100mlの5Mメタノール水溶液を、他方のセルに100mlの超純水(18MΩ・cm)を注入し、25℃で両側のセルを撹拌しながら、イオン交換膜を通って超純水中に拡散してくるメタノール量をガスクロマトグラフを用いて測定することで算出した(イオン交換膜の面積は、2.0cm2)。
3,3’−ジスルホ−4,4’−ジクロロジフェニルスルホン2ナトリウム塩(略号:S−DCDPS)5.2335g(0.01065mole)、2,6−ジクロロベンゾニトリル(略号:DCBN)2.3323g(0.013559mole)、4,4’−ビフェノール4.5086g(0.02421mole)、炭酸カリウム3.8484g(0.02784mole)、モレキュラーシーブ2.61gを100ml四つ口フラスコに計り取り、窒素を流した。35mlのNMPを入れて、150℃で一時間撹拌した後、反応温度を195−200℃に上昇させて系の粘性が十分上がるのを目安に反応を続けた(約5時間)。放冷の後、沈降しているモレキュラーシーブを除いて水中にストランド状に沈殿させた。得られたポリマーは、沸騰水中で1時間洗浄した後、乾燥した。ポリマーの対数粘度は1.24を示した。
3,3’−ジスルホ−4,4’−ジクロロジフェニルスルホン2ナトリウム塩(略号:S−DCDPS)を3.9251g(0.00799mole)、2,6−ジクロロベンゾニトリル(略号:DCBN)を2.7904g(0.01622mole)とする以外は、実施例1と同様にして重合を行い、ポリマーを得た。ポリマーの対数粘度は、1.58を示した。
実施例2においてS−DCDPSとDCBNの比率を変えてポリマーを合成し、同様の評価を行った。結果を表1に示す。また、S−DCDPS:DCBN=38:62(モル比)から得られたポリマーフィルムのIRスペクトルとTGAチャートを図2、3に示す。
実施例1においてDCBNを用いずにポリマーを合成したところ、得られたポリマーは水溶性となり、イオン伝導膜としての評価をすることは出来なかった。
実施例1においてS−DCDPSを用いずにポリマーを合成したところ、反応時間2.5時間で対数粘度2.76のポリマーが得られた。フィルムのイオン伝導性は測定限界以下だった。
実施例1においてDCBNの代わりに4,4’−ジクロロジフェニルスルホン3.8934g(0.013559mole)を用いて重合したところ、対数粘度0.70のポリマーを得るのに、16時間を要した。
4,4‘−ビフェノールの代わりにビスフェノールA5.5199gを用いる以外は実施例2と同様にして重合を行い、ポリマーを得た。ポリマーの対数粘度は、1.31を示した。作製したフィルムのイオン伝導性を測定したところ、0.14S/cmの値を示した。本フィルムの熱重量測定による3%重量減少温度は362℃であった。滴定で求めたIECは1.52を示した。メタノール透過速度は、6.61mmol/m2・secを示した。得られたフィルムを沸騰水中5時間浸積しても、膜形態を良好に保持していた。
実施例2において、2,6−ジクロロベンゾニトリルの代わりに等モル量の2,4−ジフルオロベンゾニトリルを用いてポリマーを合成した。ポリマーの対数粘度は、0.61を示した。作製したフィルムのイオン伝導性を測定したところ、0.11S/cmの値を示した。本フィルムの熱重量測定による3%重量減少温度は371℃であった。滴定で求めたIECは1.59を示した。メタノール透過速度は、4.24mmol/m2・secを示した。得られたフィルムを沸騰水中5時間浸積しても、膜形態を良好に保持していた。
実施例3においてS−DCDPS:DCBN=38:62(モル比)で得られたポリマーから作製したフィルムを用いて、発電評価を実施した。得られた結果を図4に示す。デュポン社製ナフィオン112(R)フィルムを用いて、同様に評価したものに比べ、優れた発電特性を示していることが認められた。
