Thick electrophoretically deposited (EPD) films of ligand-capped colloidal nanocrystals (NCs) typically crack when removed from the deposition solvent due to the loss of residual solvent. We report the suppression of fracture in several micrometers thick EPD films of CdSe NCs by treating the wet, as-deposited films with solutions of polymer precursor monomers, followed by UV-initiated polymerization. The monomers diffuse into voids and, for several monomers, dissolve the NCs to form a uniform dispersion in the film.
厚的电泳沉积（EPD）薄膜通常会在从沉积溶剂中去除时由于残留溶剂的损失而破裂。我们通过用聚合物前体单体的溶液处理湿的、沉积的薄膜，然后进行 UV 引发聚合，来抑制几微米厚的 CdSe NCs 的 EPD 薄膜的断裂。单体扩散到空隙中，对于几种单体，它们会溶解 NCs，从而在薄膜中形成均匀的分散体。
