Interaction between Polymer Brush and Nanoparticle: Brownian Dynamics Investigation
نویسندگان
چکیده
We use Brownian dynamics simulations to study the adsorption behavior of a nanosized particle on polymer brushes. The adsorption process, the dynamic behavior of the nanoparticle in brush, the penetration depth, and the di usion coe cient of the nanoparticle in di erent depths of the brush are all investigated for di erent grafting densities. We provide an area density Γ , which is the area average of the monomer number above the embedded nanoparticle in brush. We nd that this area density explains well qualitatively the experimental phenomenon that the nanoparticles exhibit a maximum in the adsorbed amount as a function of the grafting density of brush.

Rheology of Polymer Brushes: A Brownian Dynamics Study
We present results of Brownian dynamics simulations of polymer brushes under steady and oscillatory shear. The brush is sheared by a bare surface and the resulting solvent velocity and polymer dynamics are solved self-consistently. Under steady shear the deformation of the brush proceeds in two steps: chains tilt in the flow direction followed by a physical thinning of the brush. The brusheffec...
متن کاملA molecular dynamics simulation study of nanoparticle interactions in a model polymer-nanoparticle composite
Molecular dynamics (MD) simulations were performed on a model polymer–nanoparticle composite (PNPC) consisting of spherical nanoparticles in a bead-spring polymer melt. The polymer-mediated effective interaction (potential of mean force) between nanoparticles was determined as a function of polymer molecular weight and strength of the polymer–nanoparticle interaction. For all polymer–nanopartic...

In this research, an in-house code which uses the molecular dynamics method to study the flow of different nanofluids in the copper nanochannel and computes the thermo-physicals properties has been developed. The flow of nanofluids has been studied from hydro-thermally viewpoint and temperature jump at the wall has been applied. Parametric study to consider the effect of different parametric su...
متن کاملResponsive polymer brushes for controlled nanoparticle exposure.
We propose the design of a novel mixed polymer brush system that could act as a selective sensor with a distinct on-off switch. In the proposed system, a (single) nanoparticle (such as an antibody) is end-attached to a responsive chain, which is surrounded by a brush of nonresponsive chains. The collapse of the responsive chain leads to a protected state, where the nanoparticle is hidden in the...
متن کاملShear of polymer brushes
We have measured the normal, lateral and hydrodynamic forces that act between polymer-brush-bearing surfaces immersed in a good-solvent medium, both when stationary and when in motion with respect to each other. At low sliding velocities we find a very marked decrease in the frictional force between the surfaces, an effect interpreted in terms of a fluid interfacial layer resulting from the non...
