Computer simulation of three-arm star polymers
Polymeric liquids have unique dynamical properties that distinguish them from small molecule fluids . One of the most important examples is the strong dependence of the transport properties on the degree of polymerization N. For linear polymer chains (the most extensively studied architecture) one finds two different regimes. For chains shorter than a crossover chain length Nc the selfdiffusion...
متن کاملCollapse of telechelic star polymers to watermelon structures.
Conformational properties of star-shaped polymer aggregates that carry attractive end groups, called telechelic star polymers, are investigated by simulation and analytical variational theory. We focus on the case of low telechelic star polymer functionalities, f < or = 5, a condition which allows aggregation of all attractive monomers on one site. We establish the functionality- and polymeriza...
متن کاملHierarchical self-assembly of telechelic star polymers: from soft patchy particles to gels and diamond crystals
The design of self-assembling materials in the nanometer scale focuses on the fabrication of a class of organic and inorganic subcomponents that can be reliably produced on a large scale and tailored according to their vast applications for, e.g. electronics, therapeutic vectors and diagnostic imaging agent carriers, or photonics. In a recent publication (Capone et al 2012 Phys. Rev. Lett. 109 ...
متن کاملShear banding in simulated telechelic polymers
The response of simulated telechelic polymers to shear is investigated. End groups of short polymeric chains form temporary junctions that are continuously broken and formed over time. As in experiments, two shear bands coexist for some shear rates. This allows us to study the microscopic differences between these shear bands. We find that the lifetime of a junction is lower in the high shear r...
متن کاملTelechelic star polymers as self-assembling units from the molecular to the macroscopic scale.
By means of multiscale molecular simulations, we show that telechelic-star polymers are a simple, robust, and tunable system, which hierarchically self-assembles into soft-patchy particles and mechanically stabilizes selected, open crystalline structures. The self-aggregating patchy behavior can be fully controlled by the number of arms per star and by the fraction of attractive monomeric units...
