Fractal colloids, which find applications in the preparation of advanced materials, are currently synthesized by means of a multistep procedure that yields a low solids content dispersion. This is not well suited for certain applications such as superhydrophobic coatings. In this work, a one-step method for the synthesis of higher solids content waterborne fractal polymer dispersions is presented and it is shown that the surfaces obtained from the fractal dispersions are superhydrophobic (contact angle, θ > 150°) which is beyond the current waterborne coating technology (θ = 130°-137°). This opens the possibility for the large-scale production of waterborne superhydrophobic coatings.
分形胶体可用于先进材料的制备，目前通过多步程序合成，得到的是低固体含量的分散体。这对于某些应用（如超疏水涂层）不太适用。在这项工作中，提出了一种一步法合成更高固体含量的水性分形聚合物分散体的方法，结果表明，由分形分散体制得的表面具有超疏水性（接触角，θ>150°），这超出了目前水性涂层技术的水平（θ = 130°-137°）。这为大规模生产水性超疏水涂层开辟了可能性。
