Star Polymers: An Overview
This review article describes the synthesis, properties and some applications of star-shaped polymers. The arms constituted of homoor co-polymers of different polymers are also reviewed. Methods of synthesis of various types of starshaped polymers, including “arm first” and “core first” procedures, is given as an introduction along with some details. Then, the synthesis of star polymers (includ...
متن کاملMultiarm star polymers dynamics
Multiarm star polymers, consisting of a high number of linear homopolymer arms joined covalently to a central core, represent model soft ‘hybrid’ spheres encompassing both polymeric (arm) and colloidal (core) character. Due to this topology, the single star has a nonuniform monomer density distribution. In nondilute solutions, a liquid-like ordering occurs as a consequence of the enhanced osmot...
متن کاملAdsorption of star polymers
The adsorption of star polymers on a flat solid surface is analyzed by means of scaling arguments based on the Daoud-Cotton blob model For the adsorption of a single star, consisting of f arms compnsing each N monomers, we distinguish three regimes determined by the
متن کاملStar polymers in shear flow.
Linear and star polymers in solution are studied in the presence of shear flow. The solvent is described by a particle-based mesoscopic simulation technique, which accounts for hydrodynamic interactions. The scaling properties of the average gyration tensor, the orientation angle, and the rotation frequency are investigated for various arm lengths and arm numbers. With increasing functionality ...
متن کاملEffective interaction between star polymers
The distance-resolved effective interaction between two star polymers in a good solvent is calculated by Molecular Dynamics computer simulations. The results are compared with a pair potential proposed recently by Likos et al. [Phys. Rev. Lett. 1998, 80, 4450] which is exponentially decaying for large distances and crosses over, at the corona diameter of the star, to an ultrasoft logarithmic re...
