Description
本発明の特定の実施形態は、ソジオスルホン酸化ポリエステル樹脂粒子を水中で自己集合させる間に、同時に銀(I)イオンを還元することによる、銀ナノ粒子(AgNP)を合成する方法を提供する。バルク溶媒として水を使用するこの方法は、環境に優しく、有機溶媒を含まない(すなわち、有機物を含まない溶媒)。この方法は、ポリマー金属ナノコンポジットを調製するのに最低限しか時間を必要とせず、効率的である。理論に束縛されないが、同時にAgNPに還元しつつ、ソジオスルホン酸化ポリエステルの自己集合中に、ポリマーマトリックス内に銀イオンが捕捉されると考えられる。スルホン酸化ポリエステル-銀ナノ粒子(SPE-AgNP)は、自己集合中または図1に示されるようにポリマーを水に分散させている間に、同時に合成される。従って、ソジオスルホン酸化ポリエステルは、銀イオンの担体としても、銀ナノコンポジットの系中での合成のための有機マトリックスとしても働く。硝酸銀から銀ナノ粒子(AgNP)へと還元するために、ソジオスルホン酸化ポリエステルの自己集合中に還元剤を加え、十分に分散した粒子を得る。ポリエステルマトリックスは、AgNPの凝集を抑制すると考えられるため、重要な役割を果たす。一方、スルホン酸化ポリエステルの多孔性によって、銀イオンがポリマーマトリックス全体に拡散し、および/または吸収され、ポリエステルのスルホネート官能基との遮られていない相互作用が可能になる。銀イオンの還元に使用される還元剤も、ポリエステルマトリックス全体に自由に拡散し、ポリエステル粒子の表面および内部に十分に分散したAgNPの生成を促進する。有利なことに、このプロセスは、あらかじめ作成しておいたナノ粒子を用いる従来の方法では起こってしまうナノ粒子の凝集を最低限にする。スルホン酸化ポリマーマトリックスは、AgNPの分散を維持し、コンポジットの全体的な化学安定性および機械安定性を維持するのに重要な役割を有する。
まず、本明細書に記載されるコンポジット粉末を、スルホン酸化ポリエステル-銀ナノ粒子(SPE-AgNP)から調製し、次いで、フィラメント製造によって、コンポジット粉末をコンポジットフィラメントに変換する。
