Multilayer films composed of azide-functional polymer and polyphenylene dendrimer-stabilized gold nanoparticles with alkynes in their peripheries have been fabricated using a layer-by-layer (LBL) approach via “click” chemistry. This method permits facile covalent linking of the polymer/nanoparticle interlayers in the mixture of DMF and water, which provides a general and powerful technique for preparing uniform nanoparticle (NP) thin films. The deposition process is linearly related to the number of bilayers as monitored by UV–vis spectroscopy. The multilayer structure and morphology have been characterized by X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), and contact angle.

通过“点击”化学与聚苯撑树枝状聚合物/金纳米颗粒构建金属纳米颗粒多层

多层膜由叠氮化物官能化聚合物和聚苯撑树枝状聚合物稳定的金纳米颗粒组成，其外围具有炔烃，已通过“点击”化学方法采用逐层（LBL）方法制备。该方法允许DMF和水的混合物中的聚合物/纳米粒子中间层轻松共价连接，这为制备均匀的纳米粒子（NP）薄膜提供了一种通用而强大的技术。沉积过程与通过紫外可见光谱法监测的双层数成线性关系。多层结构和形态已通过X射线光电子能谱（XPS），原子力显微镜（AFM）和接触角进行了表征。
