<br/>In this study, we focused on the crosslink structure in the soft microsphere, and we made microsphere crosslinked with rotaxane structure.<br/>In the soft and deformable elastomer microspheres case, it can be used to generate colorless transparent films by upon evaporating the solvent from dispersions of colloidal microspheres. We discovered that tough elastomer microspheres that are crosslinked with rotaxanes can form tough and stretch bulk films upon evaporating of water from microsphere dispersions, without post-polymerization reactions (Figure).<br/>In the soft gel microspheres (microgels) case, it dual-responsive smart microgels, where thermo-responsive polymers are cross-linked by rotaxane networks, were developed. Although charged monomers, which usually afforded the pH-responsiveness for such material, were not used, the rotaxane cross-linked microgels respond to change in pH value and temperature.
