Chem. Commun., 2014, Advance Article
DOI: 10.1039/C4CC03740E, CommunicationT. Suzuki, A. Osumi, H. Minami
Multiple particles in a polymer shell, i.e. "rattle-like" capsules, have the potential to be used in electric ink or vibro-isolating and sound absorption materials because the encapsulated small particles are movable independently. Here, we demonstrate one-step preparation of the capsules containing small particles. In the final products, encapsulated particles were movable inside the capsule.
