Description
ここで、「Comp.Seg.」は、表面修飾剤の相溶化セグメントを指す。
概して、表面修飾剤は、樹脂中にナノ粒子を分散させることを補助する相溶化基と、相溶化基をナノ粒子と会合させるための結合基とを含む。密度汎関数理論計算を用いて、種々の一般的及び潜在的結合基のカルサイトに対する結合エネルギーを決定することができる。そのような計算に関する詳細は、Pendrew,J.P.;Burke,K.J.;Ernzerhof,M.;Phys.Rev.Lett.1996,3865,77から得られる。
BE=E(スラブ)+E(分子)−E(スラブ+分子) (1)
式中、E(スラブ+分子)、E(スラブ)、及びE(分子)はそれぞれ、錯体、孤立スラブ、及び孤立分子の電子エネルギーである。全ての場合において、形状をそれらのそれぞれの最小値に最適化した。
BE=E(スラブ)+E(分子)+E(水)−E(スラブ+分子) (2)
式中、E(スラブ+分子)、E(スラブ)、及びE(分子)は上で定義されており、E(水)は、単離された水分子の電子エネルギーである。
式中、「Rx.基」は反応基である。いくつかの実施形態において、反応基は、相溶化セグメントの主鎖に沿って、又は主鎖にぶら下がって位置してもよい。いくつかの実施形態では、反応基は、相溶化セグメントと結合基との間に位置してもよい。
いくつかの実施形態では、連結基が存在し、相溶化セグメントを結合基と結びつける。
例えば、いくつかの実施形態では、表面修飾剤は、ポリエーテルアミンを含む。代表的なポリエーテルアミンとしては、Huntsman Corporation,The Woodlands,Texasから商品名JEFFAMINE(登録商標)で入手可能なものが挙げられる。ポリエーテルが相溶化セグメントとしての役割を果たす一方で、アミンは、相溶化セグメントを結合基と連結する連結基である。
スルホン酸配位子を以下の通りに調製した。100g(0.167モル)のポリエーテルアミン(JEFFAMINE M−600、Mn=600、Huntsman International,LLC,Salt Lake City,Utahより入手)に、17.88g(0.146モル)の溶融したプロパンスルトン(TCI America(Portland,Oregon)より購入)を加えた。混合物を80℃に加熱し、16時間撹拌した。1H NMRスペクトルは、プロパンスルトンの完全な消費を示す。スルホン酸配位子(「JAS」)を赤茶色の液体として単離し、更なる精製なしで使用した。JAS配位子の構造は次の通りであった。
