In this work we explore the micellar phase behavior of three smart polymeric<br />

materials: PMAA-b-PDEA, PSBMA-b-PMEMA and PMEMA-b-PSVBP and their<br />

response to external stimuli such as: pH, ionic strength and temperature<br />

employing the dissipative particle dynamics (DPD) simulations and coarsegrained<br />

models. Our simulations reveal that polymeric systems can generate<br />

stable spherical micelles in a watery environment. When the polymeric micelles<br />

are subjected to external stimuli such as temperature, pH, and ionic strength<br />

they exhibit structural inversion. The micellar inversion stages on each case are<br />

described and analyzed in this document. The results obtained from these DPD<br />

simulations can contribute to elucidate the structural inversion mechanisms of<br />

stimuli- responsive polymeric micelles and are consistent with available<br />

experimental outcomes.<br />
