Coarsed-grain Modeling of HEUR Polymers in Colloidal Suspensions: Transient Networks, Rheology, and Colloid Interactions
I am a Physics Engineer from the University of Cauca, Colombia, currently working as a Project Researcher in the Computational Soft Matter Group at the University of Turku, under the supervision of Prof. Alberto Scacchi. My passion for materials science began during a research exchange in Mexico, where I synthesized calcium aluminate materials with thermoluminescent properties. I then pursued a master’s degree in Materials Science and Egineering at Queen’s University Belfast, UK, focusing my thesis on neural networks for clays. Later, during a one-year internship at the Centre for Process Innovation (CPI) in Sedgefield, UK, I gained hands-on experience in materials synthesis and characterization, working with nanomaterials such as dielectric inks and graphene oxide, as well as conducting molecular dynamics simulations of modified graphene oxide structures. I am currently applying for the Doctoral Programme in Technology at the University of Turku, where I plan to focus on simulating HEUR polymers to investigate their linking behavior and rheological properties.
My research focuses on developing a coarse-grained molecular dynamics (CG-MD) model of hydrophobically modified ethoxylated urethane (HEUR) polymers in water and colloidal suspensions to explore their sel-assembly behavior and their influence in the rheological properties of the system. Using LAMMPS simulations with Langevin dynamics, I analyze the influence of polymer concentration and transient networks in the viscosity and relaxation times of the system, aiming to optimize HEUR formulations for more stable, high-performance, and eco-friendly materials.
