Xiaobo Hu, Zhen Tong and L. Andrew Lyon One-Pot Synthesis of Microcapsules with Nanoscale Inclusions Macromolecular Rapid Communications 32
Temperature responsive microgel capsules containing poly(N-isopropylacrylamide) (pNIPAm) inclusions were prepared by one-pot synthesis. By preventing self-cross-linking during pNIPAm synthesis via low temperature, redox initiated synthesis, the majority of the encapsulated “core” polymer chains escape from the shell after decreasing the temperature. Remnant grafted/entrapped segments within the hollow particle then form thermoreversible, nanoscale inclusions within the hollow particle, providing a platform for a hierarchical nanocarrier design.
