The giant structure, formed via self-assembly of the semi-rigid polyion complex, consists of millimetre-scale cubic packed concentric cylindrical domains that are sandwiched by two homeotropically aligned outer layers. A universal relationship between the diameter of the cylinders D and the thickness of the swollen gel T is observed, as D . 0.5T, regardless the change in the concentrations of the polyanion and precursor cationic monomer. This result permits us to induce the giant concentric structure into hydrogels with tunable cylindrical sizes.Royal Society of ChemistryJournal Articleapplication/pdfhttp://hdl.handle.net/2115/52752https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/52752/1/ATT00036.pdf1744-683XAA12068335Soft Matter75188418892011enginfo:doi/10.1039/C0SM01139Hauthor
