The formation of micelles from surface-active molecules and polymers with different hydrophilic and hydrophobic parts has always been one of the important research topics. In this study, the micelle formation process for a ternary copolymer of polyethylene glycol-polycaprolactone-polyethyleneimine has been investigated by molecular dynamics simulation at coarse grain scale by Martini force field. The effectiveness of the coarse-grained model has been proven in previous studies to investigate such processes. For this purpose, several concentrations of the copolymer were prepared at body temperature and investigated by simulating the micelle formation process, such as electrostatic and van der Waals interactions. Several analyzes were used to investigate the micelle formation process. After ensuring the stability of the formed micelle, the critical concentration for the studied copolymer was obtained through coarse-grained molecular dynamics simulation, which is within the range of previous laboratory works. Also, the mechanism and driving forces of micelle formation were evaluated.
