Recyclable Oil-Absorption Foams via Secondary Phase Separation

The fabrication of micro- and nanostructures in polymers has attracted considerable attention. Here, a general method defined as secondary phase separation (SPS) is developed, which regulates the growth of polymers into multiple dimensions including one-dimensional (fiber-like), two-dimensional (flower-like), or three-dimensional (3D; sphere-like) structures. A theoretical understanding of the growth evolution in the polymer multidimensional...
