Witrynaspherulites formed under all conditions, with a higher content of intermolecular beta-sheets in the 12 presence of the surfactant above its critical micelle concentration. In addition, a denser packing was 13 observed, leading to a more stable aggregate. Molecular dynamics simulations suggested a tendency 14 WitrynaFormation of spherulites affects many properties of the polymer material; in particular, crystallinity, density, tensile strength and Young's modulus of polymers increase during spherulization. This increase is due to the lamellae fraction within the spherulites, where the molecules are more densely packed than in the amorphous phase.
