We demonstrated a facile strategy of producing superhydrophobic octadecylamine (ODA)-functionalized graphite oxide (GO) films. ODA was chemically grafted on GO sheets by the nucleophilic substitution reaction of amine groups with epoxy groups. The long hydrocarbon chain in ODA reduces the surface energy of the GO sheet. The fabricated ODA-functionalized GO film exhibited a high contact angle (163.2°) and low hysteresis (3.1°). This method is promising in terms of low-cost and large-scale superhydrophobic coatings and has potential applications for surface modification of GO paper or other GO-based composite materials.
我们展示了一种生产超疏水十八胺（ODA）功能化氧化石墨（GO）薄膜的简便策略。通过胺基与环氧基的亲核取代反应，ODA 被化学接枝到 GO 片上。ODA 中的长碳氢链降低了 GO 片的表面能。所制备的 ODA 功能化 GO 薄膜表现出高接触角（163.2°）和低滞后（3.1°）。就低成本和大规模超疏水涂料而言，这种方法具有广阔的应用前景，并且有可能应用于 GO 纸或其他基于 GO 的复合材料的表面改性。
