文摘
A dynamics density functional theory approach was presented to investigate the polymer-mediated nanoparticle deposits on a solid surface. The equilibrium and nonequilibrium behaviors of nanoparticles in the flexible linear, flexible star, semiflexible linear, and semiflexible star polymer solutions were investigated to evaluate the polymer-induced entropic effects and solvent-mediated hydrodynamic interactions. The theoretical results are in remarkable agreement with the Brownian dynamic simulation data, providing the quantitative verification of particle agglomeration and polymer depletion. The description at the microscopic level reveals new insight into the structure鈥揻unction relationship of semidilute polymer鈥損article suspensions under confinement.
