Anticorrosion Property Studies of Graphene Based Nanocomposites
摘要
本文簡介石墨烯及其高分子奈米複合材料在金屬防腐蝕應用，並研究一系列環氧樹脂、環氧樹脂/石墨烯氧化物、以及環氧樹脂/官能基化石墨烯奈米複合材料之金屬防腐蝕性質。結果顯示，化學官能基化改質之石墨烯，由於其官能基與高分子基材形成化學鍵結，可有助於提升石墨烯材料在高分子基材中之分散性，其分散性將優於單純物理混摻所製備之奈米複合材料。利用官能基化石墨烯擁有很高的視徑比與良好的分散，能有效抑制腐蝕因子接觸金屬基板，避免及延緩鐵片的腐蝕，因此大幅度提升材料抗腐蝕之性能。本研究以電化學量測來探討奈米複合材料的抗腐蝕性質，利用環氧樹脂及有優越的金屬防蝕特性，導入分散良好的石墨烯，成功製備出耐高溫型、長效型金屬防腐蝕材料。

In this manuscript, we introduce the anticorrosion applications of graphene and graphene based nanocomposites; and the anticorrosion properties of a series of epoxy resin, epoxy/graphene oxide and epoxy/functional graphene oxide nanocomposites were compared. As a result, the chemical bonding between the functional graphene oxide and polymer matrix could improve the dispersion of graphene materials in the polymer matrix, and its dispersion will be better than a simple physical blending method. The high aspect ratio and well-dispersed the functional graphene oxide in polymer matrix can effectively inhibit the corrosion factor diffusing onto the metal substrate, which preventing and delaying the corrosion of metal surface, and therefore enhance the performance of corrosion-resistance substantially. In this study, the electrochemical measurements for anticorrosive properties of nanocomposites were studied. In addition to the excellent anticorrosion properties of epoxy resin, we successful develop a series of durable anticorrosion coatings especially for high temperature and long-life resistance based on the epoxy/functional graphene oxide nanocomposites.
