Toward the Highly Ordered Lamellar Hybrid Membrane for Molecular Sieving by One-Pot Self-Assembly of Hybrid Hyperbranched Polymer

Ordered lamellar hybrid membranes are of great interest,due to their application as functional materials,including molecular sieving,biosensors,optical devices,and drug,as well as gene deliveries,but their fabrication remains challenging because three critical issues regarding synthesis of regular nanosheets,interfacing,and their spatial distribution in a polymer matrix are difficult to address simultaneously.Here,we fabricated a well-defined hybrid lamellar membrane through one-pot self-assembly,whose structure consisted of alternating layers of hydrophilic hyperbranched poly(ether amine)(hPEA)and polyhedral oligomeric silsesquioxane(POSS).
