We present a two-step route to produce a hierarchical cauliflower-like gold structure that involves the adsorption of gold nanoparticles described by the random sequential adsorption (RSA) model, followed by the electrochemical growth on the surfaces of the primary gold nanoparicles. The structure was confirmed using scanning electron microscopy (SEM), energy dispersive spectrometer analysis (EDS), and X-ray diffraction (XRD). After fluoroalkylsilane modification, the cauliflower-like structured surface exhibits a high contact angle and a low sliding angle.
我们提出了一种两步法来制备分级菜花状金结构，该方法包括通过随机顺序吸附（RSA）模型描述的金纳米颗粒吸附，然后在初级金纳米颗粒表面进行电化学生长。使用扫描电子显微镜（SEM）、能量色散光谱分析（EDS）和X射线衍射（XRD）对该结构进行了确认。经过氟代烷基硅烷修饰后，菜花状结构表面呈现出高接触角和低滑动角。
