Peculiarities of NMR relaxation in micellar gels of Pluronic F-127

Based on the ¹H relaxation of transverse nuclear magnetization of triblock-copolymer Pluronic F-127 in D₂O, we proposed a model of the associated pluronic structure in which the polyethylene oxide of molecules in neighboring micelles are intertwined in regions of overlapping micellar coronas, while the polypropylene oxide cores of the micelles play a role of nodes in the 3D network.
