“…9 In addition, the properties of the metal complexes, such as electrochemical and photophysical properties, could provide additional features to the block copolymers4f,j, 8, 9c and may even lead to modification of the intrinsic properties of the polymers through their supramolecular chemistry, resulting in totally unique features that are not found in either the polymers or the metal complexes alone 8. 9d,e, 10a However, so far, only a few studies have reported the hybrid properties found in metallosupramolecular block copolymers, such as the effect of counter ions of the metal complexes on the nanostructure of the block copolymers 9d. 10a…”

ABSTRACT:The dynamic vulcanization of reclaimed-tire rubber (RTR) and homopolypropylene (PP) was performed by melt-mixing using either a sulfur crosslinking agent, maleic anhydride (MA), dicumyl peroxide (DCP), or the combination of MA and DCP, in two consecutive machines, first a two-roll mill and then a counterrotating twin-screw extruder. In the case of applying a sulfur crosslinking agent, it was demonstrated that the RTR/PP blend at the ratio of 30/70 had the highest impact strength. This could be attributed to the limitation of carbon black in the blend. When the combination of MA and DCP was applied, the result was higher impact strength of the blend at the same ratio. This could be attributed to not only the cohesion between the polymer chains in each phase, PP phase and rubber phase, but also the interfacial adhesion between PP and RTR chains in these two phases. For comparison, the GRT/PP blends with and without sulfur crosslinking agent were prepared as well. All these blends showed low impact strength, which was nearly the same as that of PP. The effects of different crosslinking agents on dispersion and distribution of rubber domain size, viscosity, and percentage crystallinity were also studied.

Terpyridylplatinum(II)-based metallosupramolecular triblock copolymers with hydrophilic alkynyl ligands have been synthesised and characterised. As a result of the intrinsic properties of Pluronics, reversible temperature-induced micellisation occurred at high temperature leading to aggregation of the platinum(II) complex moieties through Pt⋅⋅⋅Pt and π-π interactions, resulting in significant UV/Vis absorption and near-infrared (NIR) emission spectral changes. The critical micelle temperatures of the complexes were found to vary from 21 to 30 °C due to differences in the hydrophilicity of the alkynyl ligands and the electrostatic repulsions between the positively charged platinum(II) complex moieties. One of the complexes with pH-responsive CH2NMe2 groups on the alkynyl ligand was found to show NIR emission that is sensitive to both pH and temperature. Such dual-responsive behaviour has been ascribed to the modulation of the self-assembly of the complex moieties by temperature-induced micellisation and the changes in the hydrophilicity as well as electrostatic interactions upon protonation/deprotonation of the CH2NMe2 groups on the alkynyl ligand.

Classical dynamical density functional theory (DDFT) is one of the cornerstones of modern statistical mechanics. It is an extension of the highly successful method of classical density functional theory (DFT) to nonequilibrium systems. Originally developed for the treatment of simple and complex fluids, DDFT is now applied in fields as diverse as hydrodynamics, materials science, chemistry, biology, and plasma physics. In this review, we give a broad overview over classical DDFT. We explain its theoretical foundations and the ways in which it can be derived. The relations between the different forms of deterministic and stochastic DDFT as well as between DDFT and related theories, such as quantum-mechanical time-dependent DFT, mode coupling theory, and phase field crystal models, are clarified. Moreover, we discuss the wide spectrum of extensions of DDFT, which covers methods with additional order parameters (like extended DDFT), exact approaches (like power functional theory), and systems with more complex dynamics (like active matter). Finally, the large variety of applications, ranging from fluid mechanics and polymer physics to solidification, pattern formation, biophysics, and electrochemistry, is presented.
