Fibril crystal growth of diblock copolymers is meaningful in the fields of nanotechnology [1] and neurodegenerative diseases [2].We report dynamic Monte Carlo simulations of a lattice model of diblock copolymers performing the crystallization-driven fibril-micelle growth under two circumstances of solutions: sporadic crystals with the feeding mode of constant polymer concentrations,and massive crystals with the depleting mode of decaying polymer concentrations [3].We found that anisotropic driving forces arc a prerequisite condition of steady growth of fibril crystals.In addition,lamellar crystal width is confined by the non-crystalline block below a critical concentration that shifts down with the decrease of the non-crystallizable block fractions.
