Synthesis from Molecule into 3D Polyamide 6 Microspheres Stacked Polyhedrons via Self‐Assembly

다국어 초록 (Multilingual Abstract)

Self‐assembly provides the basis for a procedure used to organize larger objects into regular, 3D microsphere stacked polyhedrons. A novel approach is described for the fabrication of 3D structured micrometer‐scale polyhedrons which are packed with nanosized spheres in the order of 400 nm by in situ polymerization using phase inversion technology. The extended polyhedrons can assemble into decimeter‐level ordered materials. The side length of an individual polyhedron can be effectively tuned from 10 to 100 µm through several ways. This method realizes directly self‐assembly from molecule to regular extended polyhedrons materials. The process is primarily based on in situ anion polymerization of lactam in two‐phase system whose self‐assembly is driven by hydrogen bonds' force and polyethylene glycol stepwise crystallization synergistically. The results suggest that this strategy for self‐assembly can be applied to design nonplanar complex geometric structure materials. In the future, polyhedrons packed with microspheres may be possible to build more complex 3D, self‐assembly device modules for advanced materials.
