We report on the assembly of gold nanorods functionalized with poly(ethylene glycol) in aqueous suspensions by electrostatic control and hydrogen bonds provided by polyelectrolyte linkers (.., interpolymer complexation processes). Small-angle X-ray scattering reveals that the quality and stability of the assemblies into the hexagonal columnar phases increase with temperature. Our study shows that the lattice constant of the ordered structures is tunable over a wide range of values by the interplay between electrostatic and hydrophobic effects.
我们报道了通过静电控制和聚电解质连接体提供的氢键（即聚合物间络合过程），在水悬浮液中组装聚乙二醇功能化的金纳米棒。小角X射线散射表明，组装成六方柱状相的质量和稳定性随温度升高而增加。我们的研究表明，通过静电和疏水效应之间的相互作用，有序结构的晶格常数可在很宽的值范围内调节。
