Synthesis of hybrid colloidal particles with complex and hierarchical structures is attracting much interest theoretically and technically in recent years, but still remains a tremendous challenge. Here, we present a mild and controllable wet-chemical method for the synthesis of silver nanocube (Ag NC)-organosilica hybrid particles with finely tuned numbers (with one, two, three, four, five, or six) and sizes of organosilica petals, by simply controlling the affinity with Ag NC/nature, amount, and prehydrolysis process of alkoxysilanes. The morphologies of hybrid colloidal particles have an obvious influence on the surface wettability of the hybrid particle-based films. More and larger organosilica petals can increase the surface hydrophobicity of the hybrid particle-based films.
近年来，具有复杂和分级结构的杂化胶体粒子的合成在理论和技术上引起了极大的兴趣，但仍然是一个巨大的挑战。在这里，我们提出了一种温和可控的湿化学方法，用于合成具有精细调控数量（一个、两个、三个、四个、五个或六个）和尺寸的银纳米立方体（Ag NC）-有机硅杂化粒子，通过简单地控制 Ag NC/天然物、烷氧基硅烷的用量和预水解过程的亲和力。杂化胶体粒子的形态对基于杂化胶体粒子的薄膜的表面润湿性有明显的影响。更多和更大的有机硅花瓣可以增加基于杂化胶体粒子的薄膜的表面疏水性。
