Abstract
The conformational properties of a polymer chain adsorbed on an attractive spherical nanoparticle are studied by using Monte Carlo simulations. The adsorption degree of polymer is described by the number of adsorbed monomers n a and the length of adsorbed block l a . The configuration of the adsorbed polymer on a nanoparticle is described by trains, loops, and tails. We find three different structures for the adsorbed polymer: a structure with trains, loops, and tails at small polymer-nanoparticle interaction strength ε pn , a structure with a train and a tail at large ε pn , and a structure with trains and loops at large n a . In addition, we find that the mean number of adsorbed monomers <n a > is scaled with l a as <n a > ~ l a α at ε pn ≥ 1, and the exponent α increases with ε pn . Our results indicate that both the adsorption degree and the configuration of the adsorbed polymer are dependent on the polymer-nanoparticle interaction strength, the number of adsorbed monomers, and the length of adsorbed block.
