Micromechanical model for isolated polymer-colloid clusters under tension.
Binary polymer-colloid (PC) composites form the majority of biological load-bearing materials. Due to the abundance of the polymer and particles, and their simple aggregation process, PC clusters are used broadly by nature to create biomaterials with a variety of functions. However, our understanding of the mechanical features of the clusters and their load transfer mechanism is limited. Our ma...
متن کاملEffect of polymer–polymer interactions on the surface tension of colloid–polymer mixtures
The density profile and surface tension for the interface of phase-separated colloid–polymer mixtures have been studied in the framework of the square gradient approximation for both ideal and interacting polymers in good solvent. The calculations show that in the presence of polymer– polymer excluded volume interactions the interfaces have lower widths and surface tensions compared to the case...
متن کاملPenetrability in model colloid–polymer mixtures
In order to study the effects of penetrability in mixtures of dissimilar particles we consider hard ~colloidal! spheres and penetrable spheres. The latter may be taken to represent ideal, noninteracting polymer coils. Polymers and colloids interact by means of a repulsive step-function pair potential, which allows for insertion of colloids into the polymer coil. The potential strength is obtain...
متن کاملGelation in Model Colloid-Polymer Mixtures
Mode coupling theory (MCT) is used to model gel formation in mixtures of colloidal particles and nonadsorbing polymer. The polymer induces an effective, short-range attraction among the colloids, which is modeled by a depletion attraction of the Asakura-Oosawa form. This enables the MCT to be solved analytically for dilute systems, leading to a prediction, free of adjustable parameters, of the ...
متن کاملUnwinding globules under tension and polymer collapse.
Polymer collapse is known to be mediated by the formation of pearls. These intermediate structures behave as small globules under tension. The globule size is studied by molecular dynamic simulations as a function of the strength of an external stretching force applied to its ends, for different values of the chain length. A very strong first-order-like transition from a compact globule state t...
