Description
本出願は、2008年、11月25日に出願された「ボロン酸−リン酸錯化に基づく自己ドープ型ポリアニリンナノ粒子分散液(SELF−DOPED POLYANILINE NANOPARTICLE DISPERSIONS BASED ON BORONIC ACID−PHOSPHATE COMPLEXATION)」と題する米国特許仮出願第61/117,841号の利益を主張し、その全体を参照により本明細書に援用する。
原料。3−アミノフェニルボロン酸塩酸塩(3−APBA)及び過硫酸アンモニウムを、Aldrich Chemical Inc.から購入した。フッ化ナトリウム、塩化カリウム、リン酸ナトリウム及びリン酸(85%)を、Fisher Scientificから購入した。バルク蒸留水を濾過し、次いで、Milli−Q−Academic A10(Millipore Corporation)を使用してイオン交換して18.2MΩcmの品質の水を得た。インジウムドープ酸化錫コートガラススライド(ITO、6±2Ω/スクエア)をDelta Technologies Ltd.から購入した。金の櫛形アレイ微小電極(IDA)を、North Carolina State UniversityにおけるBiomedical Microsensors Laboratoryから入手した。これらのアレイの各々は、0.069mm2の総露出部を有する20μmの空隙幅を有する2.8mm×0.075mmの金電極を含んだ。TEM formvar−炭素被覆銅格子(400メッシュ)を、CANEMCO−MARIVACから購入した。
フッ化物及びリン酸の存在下の3−APBAの重合は、安定なPABA分散液をもたらす。0.1MのHCl及びフッ化物を使用して2−15nmの粒径からなるPABA分散液を得ることは、報告されているが、わずか1日間しか懸濁された状態に留まらない。28対照的に、リン酸及びフッ化物の存在下で調製されたより大きなサイズのPABA粒子分散液は、無限に安定であり、5mg/mLの濃度で2カ月間にわたり沈殿は観察されなかった。これらの結果は、塩酸に対するリン酸中の分散液の安定性は、リン酸のボロン酸置換基との相互作用に起因することを示唆している。
材料。3−アミノフェニルボロン酸塩酸塩(3−APBA)、シュア/シール(Sure/Seal)(商標)無水メタノール及び1−プロパノール、及び過硫酸アンモニウムをAldrich Chemical Inc.から購入した。フッ化ナトリウムをFisher Scientificから購入した。無水エタノールをCommercial Alcohols Inc.から購入した。バルク蒸留水を濾過し、次いで、Milli−Q−Academic A10(Millipore Corporation)を使用してイオン交換して18.2MΩ.cmの品質の水を得た。
熱処理された及び熱処理されていないPABAフィルムコート鋼サンプルの動電位分極及び開路電位測定が、それぞれ図15及び16に示されている。リン酸を含むメタノール中の分散液で調製されたフィルムを真空下で一晩中120℃に維持した。熱処理され架橋されたフィルムは、腐蝕へのより高い抵抗性を示した。
