dc.description.abstract | Shape-tunable block copolymer (BCP) particles have attracted significant attention due to their applications as smart materials. Herein, we report iodine (I2)-mediated doping of polystyrene-block-polybutadiene (PS-b-PB) particles as a facile strategy to transform spherical BCP particles into nonspherical shaped particles. Upon introducing the I2 molecules to internally phase-separated spherical PS-b-PB particles, I2 selectively reacts with the double bonds in PB blocks while leaving the PS block unaffected. Monitoring the shape-transformation process reveals a gradual structural transition from spheres to oblates and ellipsoids as a function of reaction time, consistent with the increasing conversion of the double bonds into I2-doped cation radicals. Consequently, the interfacial tension of I2-doped PB blocks decreases, neutralizing the interfacial interaction of BCP and its surroundings, thereby restructuring the spherical particles into shape-anisotropic forms. Furthermore, the versatility of I2-mediated shape transition is demonstrated by applying the same chemistry to polystyrene-block-poly(4-vinylpyridine) BCP particles. Finally, spheroidal particles doped with I2 exhibit photothermal heating behavior, highlighting their potential application as photothermal agents.,Iodine-mediated chemical modification approach was developed for the facile shape transformation of block copolymer colloidal particles., | - |
