title: A cauliflower-like gold structure for superhydrophobicity.
abstract: 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.
