文摘

The aggregation and confined crystallization of semicrystalline diblock copolymers (PM-b-PAA) in the presence of polyethylene polyamine (PPA) was studied. Dual confinements collectively affected the self-assembly and crystallization behavior of crystalline micelles. ‘Chemical confinement’ from hydrogen bonds or ionic bonds and ‘physical confinement’ of the network structure which developed by hydrogen bonds among PPA, PM-b-PAA and H2O.
