我们展示了一种生产超疏水十八胺（ODA）官能化氧化石墨（GO）薄膜的简单策略。ODA通过胺基与环氧基的亲核取代反应化学接枝到GO片上。ODA中的长烃链降低了GO片的表面能。所制造的ODA官能化的GO膜表现出高接触角（163.2度）和低滞后（3.1度）。该方法在低成本和大规模超疏水涂层方面具有前景，并且在GO纸或其他GO基复合材料的表面改性方面具有潜在的应用前景。
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 degrees) and low hysteresis (3.1 degrees). 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.
