A new package, including polyurethane foam wrapped with superhydrophobic ZnO microrods/carbon cloth with long-life elasticity, was fabricated and was utilized for oil spill clean-up. First, the carbon cloth (CC) was coated with ZnO microrods, which were modified with stearic acid (SA) to obtain superhydrophobic and superoleophilic properties. The coating process was conducted in mild conditions, involving the hydrothermal growth of ZnO microrods on the surface of the carbon cloth. The obtained hydrophobic sample was modified to a superhydrophobic one by adsorption of stearic acid (SA) on its surface. The prepared sample (CC/ZnO/SA) was characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectra (FTIR), attenuated total reflectance Fourier-transform infrared spectroscopy (ATR-FTIR), and contact angle measurements. The prepared sample shows a water contact angle (WCA) of 160°. A piece of polyurethane foam was wrapped with the prepared superhydrophobic CC/ZnO/SA making an oil collecting package, which can float on the water surface and absorb various oils from the water surface in both static and turbulent conditions very quickly. The prepared package exhibits excellent mechanical robustness and can be used several times for oil/water separation without capacity decrease. The kinetics of oil spill absorption by the prepared package were studied, too.

使用包裹有超疏水性ZnO微棒/碳布的聚氨酯泡沫制造溢油收集器组件。

制造了一种新包装，其中包括包裹有具有超长寿命弹性的超疏水ZnO微棒/碳布包裹的聚氨酯泡沫，并用于溢油清理。首先，在碳布（CC）上涂以ZnO微棒，然后将其用硬脂酸（SA）改性以获得超疏水和超亲油性。涂覆过程在温和的条件下进行，包括在碳布表面上水热生长ZnO微棒。通过将硬脂酸（SA）吸附在其表面上，将获得的疏水性样品改性为超疏水性样品。通过扫描电子显微镜（SEM），X射线衍射（XRD），傅立叶变换红外光谱（FTIR），衰减全反射傅里叶变换红外光谱（ATR-FTIR）对制备的样品（CC / ZnO / SA）进行表征，和接触角测量。制备的样品的水接触角（WCA）为160°。用制备的超疏水CC / ZnO / SA包裹一块聚氨酯泡沫，制成集油包装，该包装可以漂浮在水表面上，并且可以在静态和湍流条件下迅速吸收水表面的各种油。所制备的包装具有优异的机械强度，可多次用于油/水分离而不会降低容量。还研究了所制备的包装物吸收溢油的动力学。它可以漂浮在水面上，并能在静态和湍流条件下迅速吸收水面上的各种油脂。所制备的包装具有优异的机械强度，可多次用于油/水分离而不会降低容量。还研究了所制备的包装物吸收溢油的动力学。它可以漂浮在水面上，并能在静态和湍流条件下迅速吸收水面上的各种油脂。所制备的包装具有优异的机械强度，可多次用于油/水分离而不会降低容量。还研究了所制备的包装物吸收溢油的动力学。
