  • Title: Porous self-supporting film of semi-flexible supracolloidal chains of diblock copolymer micelles.
    Author: Lee K, Kim JY, Kim K, Jeon J, Kang H, Sohn BH.
    Journal: J Colloid Interface Sci; 2021 Oct 15; 600():804-810. PubMed ID: 34052531.
    Abstract:
    Patchy micelles of diblock copolymers can be polymerized into a linear supracolloidal chain. We measure the persistence and contour lengths of supracolloidal chains coated on a solid substrate to evaluate their flexibility. Based on the analysis, the chain is semi-flexible, and the conformation is suitably explained by the worm-like chain model. In addition, utilizing a spin-coating technique with the semi-flexible nature of the chains, we produce a self-supporting film of supracolloidal chains having nanoscale pores essentially from colloidal constituents that tend to form dense packing if there is no prior organization of them into a semi-flexible chain.
