Hierarchical self‐assembly of Y‐shaped amphiphilic triblock polyurethane/poly(acrylic acid) complexes: Giant vesicles,vesicles, 3D network,and bulk structures

A simple and effective approach to induce hierarchical self‐assembly of Y‐shaped amphiphilic triblock polyurethane/poly(acrylic acid) complexes system in aqueous media is reported here. Hydrogen bonding interactions and electrostatic repulsive forces, which can be controlled by regulating the pH condition of complexes solution, were the main driving forces to induce morphological transitions. With the gradual decrease of pH value, a variety of micro‐/nanostructures including giant vesicles, small vesicles, multi‐layer three‐dimensional (3D) porous network structures and “bulk” structures were successively obtained. Among these structures, the micron‐scale multi‐layer 3D porous network structure formed from block copolymer/homopolymer complexes was rarely reported. Therefore, this research demonstrates that the hierarchical self‐assembly of polymers complexes in aqueous media is a viable approach to construct different interesting micro‐/nanostructure assemblies, and supplies a new clue for the fabrication of multi‐layer 3D porous network structures. © 2018 Wiley Periodicals, Inc.

An investigation of particle deposition mechanisms during impregnation of dual‐scale fabrics with micro particle image velocimetry

Injection moulding processing of composite materials most often includes infiltration of a thermoset resin into a multi‐scale porous fabric. Controlling the fluid flow within the multi‐scale fabric is essential for the quality of the final composite material, since the transport of fluid between regions with different scales is of importance for phenomena such as void formation and filtration of particle doped resins. Hence, the transient flow behaviour in dual scale porous media is investigated in detail with Micro Particle Image Velocimetry. These experiments show that the fluid transport between the two scales can be controlled by the injection velocity. Validation of the measured velocity fields furthermore shows excellent agreement with theory and that transport between the two scales can be substantial at the flow front but negligible up‐stream it.

Numerische Simulation von Mehrkomponenten‐Diffusion und Gleitströmung in mikroporösen Medien

A method is presented, which enables the locally resolved calculation of multi‐component gas transport in microporous media. The theoretical basis is formed by a fluid‐dynamic model that comprises separate mass and momentum balances of each component in the gas mixture. By introducing component‐specific slip boundary conditions, the model is made applicable to regimes of increased Knudsen numbers. After implementation into a commercial CFD‐program the motion of a binary gas mixture in a virtual microporous structure is simulated. Analysis of the calculated velocity fields makes it possible to determine structural parameters that can be used in relevant 1D‐models.     

RAFT (Reversible addition–fragmentation chain transfer) crosslinking (co)polymerization of multi‐olefinic monomers to form polymer networks

The use of reversible addition–fragmentation chain transfer (RAFT) crosslinking (co)polymerization of multi‐olefinic monomers to produce three‐dimensional polymer networks is reviewed. We give specific attention to differences between RAFT and conventional processes, differences between RAFT and other forms of reversible deactivation radical polymerization (such as atom transfer radical and nitroxide‐mediated polymerizations) and the dependence of the polymerization process and network properties on RAFT agent structure. This knowledge is important in network optimization for applications as dynamic covalent polymers (in self‐healing polymers), as porous polymer monoliths or gels (used as chromatographic media, flow reactors, controlled release media, drug delivery vehicles and in molecular imprinting) and as coatings. © 2014 Society of Chemical Industry     

Deep eutectic solvents: designer fluids for chemical processes

The increasing demand for multi‐task green solvents has spurred the development of next‐generation liquid media such as deep eutectic solvents (DESs), which have recently attracted increased attention. DESs are mixtures of salts and complexing agents, having freezing points lower than those of starting individual components. Similarly to ionic liquids, DESs exhibit distinctive properties such as chemical and thermal stability, biodegradability, non‐flammability, and cost effectiveness. These features account for their wide range of applications, e.g. as extractants, reactants, catalysts, reaction media, additives, and lubricants. This review summarizes the recent research efforts directed at exploring the potential applications of DESs in various chemical processes. With the rapid publication of reports on this new generation of solvents, other roles also are expected to be seen sooner or later. © 2017 Society of Chemical Industry
