Abstract: Spherulite is an important crystal growth form in many organic and inorganic substances. In the sol-to-gel transition of the N-lauroyl-L-glutamic acid di-n-butylamide (GP-1)/propylene glycol (PG) system, the formation of spherulitic fiber network was observed in situ by optical microscopy. The growth mechanism of the spherulite in the gelation process was examined quantitatively. A constant growth rate along the radial direction of the spherulite was ascribed to the surface kinetics controlling mechanism, in which a constant supersaturation throughout the spherulitic growth may be induced by the topological structure of the densely branching morphology in this gel network. Our results also indicate that the engineering of a fiber gel network can be attained via crystallization strategies, since spherulitic growth is a typical example that construction of supramolecular structure occurs as a consequence of the crystallization from dilute solutions. © World Scientific Publishing Company.
