Dispersion Polymerization of Polystyrene Particles Using Alcohol as Reaction Medium
In this study, monodisperse polystyrene nanospheres were prepared by dispersion polymerization using alcohol as reaction medium to prepare colloidal clusters of the latex beads. Polyvinylpyrrolidone (PVP) and 2-(methacryloyloxy)ethyltrimethylammonium chloride (MTC) were used as dispersion stabilizer and comonomer, respectively. The particle size could be controlled by adjusting the reactant com...
متن کاملParticle?Stabilized Materials: Dry Oils and (Polymerized) Non?Aqueous Foams
Oil (liquids with low surface tension and practically immiscible with water) drops can be dispersed in air if relatively oleophobic particles are available. However, such particles with oil-repellent surfaces cannot simply be prepared by controlling the particle surface chemistry alone. Herein the preparation of oil-in-air materials (oil marbles, dry oils) by changing the wetting behavior of pa...
متن کاملNon-equilibrium pattern selection in particle sedimentation
In this paper, we explain some well known experimental observations in fluid solid interaction from a thermodynamic perspective. In particular we use the extremum of the rate of entropy production to establish the stability of specific patterns observed in single and multiparticle sedimentation in an infinite fluid and the sedimentation of spheres in the presence of walls. While these phenomena...
متن کاملParticle-Dynamics Approach to Non-Equilibrium Phenomena
A particle-dynamics simulation is a tool for investigating nonequilibrium phenomena accompanied with hydrodynamic, thermodynamic motions, and even with phase transitions. In this article, several applications of the particledynamics simulation and a new computational method of particle dynamics are reported.
متن کاملDispersion in Heterogeneous Porous Media: One-Equation Non-equilibrium Model
Abstract. In this paper, the method of large-scale averaging is used to develop two different oneequation models describing dispersion in heterogeneous porous media. The first model represents the case of large-scale mass equilibrium, while the second represents the asymptotic behavior of a twoequation model obtained by large-scale averaging. It is shown that a one-equation, non-equilibrium mod...
