This study reveals how the polystyrene-<i>block</i>-poly(2-vinylpyridine) (PS-<i>b</i>-P2VP) asymmetry governs the chain adsorption conformations (<i>trains</i>, <i>loops</i>, and <i>tails</i>) on PbBr₂ surfaces and its complexation outcome. Under static conditions, the process is kinetically limited by micellar diffusion. Upon reaching the PbBr₂ surface, the strong pyridine-Pb²⁺ coordination induces a restructuring of the micelle core. For asymmetric PS-<i>b</i>-P2VP with long P2VP blocks, a thin PS shell allows the P2VP core to deform and spLangmuir : the ACS journal of surfaces and colloidsMicelle-Mediated PbBr&lt;sub&gt;2&lt;/sub&gt; Complexation: Influence of Block Copolymer Architecture and Mixing Conditions.PMC12713784NSTC 112-2811-E-006 -042 -MY2NSTC 111-2221-E-006-232-MY3Junisu BASun YSfalseMicelle-Mediated PbBr&lt;sub&gt;2&lt;/sub&gt; Complexation: Influence of Block Copolymer Architecture and Mixing Conditions.Block copolymer micelles mediate PbBr₂ complexation through two distinct pathways: an architecture-dependent interfacial process under static conditions and a shear-dominated mechanism under dynamic mixing.
