Ice-Templating of Core/Shell Microgel Fibers through 'Bricks-and-Mortar' Assembly

A ‘bricks‐and‐mortar’ assembly approach can be used to create well‐ defined fibers on the microscale with alternating organic‐inorganic arrangement through a simple ice‐templating strategy. The fibers are constructed from closely packed monodisperse inorganic nanoparticles@PNIPAm core/shell microgels. A series of functional ‘bricks’, such as core/shell and hollow nanoparticles are prepared.
