Colloidal particles can be utilized as an effective building block for a variety of superstructures such as colloidal molecules and lattices through self-assembling processes. In particular, they can assemble into a linear colloidal chain by directional attraction with orthogonal repulsion between the particles. A colloidal chain can be considered as a nanoscale polymer consisting of colloidal monomers. In this study, we first polymerized patchy micelles of block copolymers into a linear colloidal chain and then coated them onto a solid substrate. We evaluated their persistence and contour lengths, which allowed the assessment on the flexibility of colloidal chains. According to the analysis, we can describe the colloidal chains semi-flexible and explain their conformations by the worm-like chain model for conventional polymers. In addition, we were able to produce a self-supporting film of the colloidal chains, which has microscopic pores due to the semi-flexible nature of the chains. |
