A numerical model, implemented using smoothed particle hydrodynamics within the LAMMPS framework, integrates Butler-Volmer kinetics and Stokes-Einstein equation-based approximation for polymer diffusion. The model, applied to both planar and pore electrode geometries, exhibits a distinct two-phase growth mechanism: an initial rapid deposition phase followed by a diffusion-limited regime which is continuously hindered by the forming polymer network and leads to self-limiting film growth. Complementary ex-situ and in-situ atomic force microscopy experiments corroborate the simulation results and are consistent with the two growth phases theory. These findings not only enhance the fundamental understanding of the electrodeposition process but have also laid the groundwork for future in-situ experiments and computational models.en-USPolymer chemistryComputational chemistryComputational physicsComputational modellingPolymer electrodepositionPolymer thin filmsSelf-limiting film growthThesis/Dissertation2025-05-220009-0002-1228-2618
