“…As a final comparison, the properties of our microchannel polymers are plotted alongside the reported compressive moduli of other low‐density polymer foams As previously mentioned, literature reports typically contain data across only a very limited density range, and generally only the compressive moduli are reported. The data we gathered are shown collectively in Figure , and the density and compressive moduli are not normalized to neat material values because these values were not provided in the literature.…”

This cover by Eric Schmid, David Salem and colleagues shows an SEM of a microvascular epoxy produced by sacrificial removal of PLA fibers. In this example, the microchannel volume fraction is 0.6, and the (18 μm diameter) channels are primarily oriented longitudinally, with fewer microchannels in the transverse direction. Tensile, flexure, and compression properties were characterized and modeled over a wide range of microchannel fractions and different microchannel orientations, demonstrating the ability to engineer the properties of these materials for structural thermal insulation applications, and for applications requiring liquid transport through the polymer for thermal management, self-healing and various biomimetic functions.

We summarize statistical thermodynamics of two typical polymerization systems to relate thermodynamic quantities to the properties of hyperbranched polymers(HBPs) such as average degree of polymerization(DP), radius of gyration, and branching density. An attempt is made to obtain the regulation mechanism of structure and properties of HBPs. Starting from the physical viewpoint, the isothermal compressibility has been associated with the weight average DP of polymers that is interpreted as the spatial correlation of monomers due to polymerization. The subchain is employed to derive the mean square radius of gyration and hydrodynamics radius, and a calculation is implemented in terms of the adjacent matrix of an HBP. Furthermore, the scaling behavior of the system is studied to give the generalized scaling law. The average properties of HBPs under the semi-batch mode are also presented by means of the generation function method. In addition, a Monte Carlo simulation method based on the growth generation is proposed, by which the spatial structure of an HBP can be easily analyzed in detail. As an application, the effect of cyclization, nonequal reactivity, and solvent quality on the polymerization is also carried out.

Amine‐functionalized natural zeolites prepared through plasma polymerization for enhanced carbon dioxide adsorption

Solution‐based amine absorption technologies have been widely applied for CO2 capture, but they have several drawbacks. This paper reports on the synthesis of the first solid‐state amine adsorbent prepared through a simple plasma polymerization and deposition on physicochemically modified natural mordenite–clinoptilolite zeolite. The plasma deposition of amine polymer under certain conditions resulted in a significant increase in surface area‐weighted CO2 adsorption capacity as the natural zeolite. The strength of the interaction between CO2 and the adsorbent was weaker for the plasma polymer‐modified zeolite than without the plasma coating, which may facilitate regeneration. Both indications make the amine plasma polymer‐based zeolite adsorbent a good candidate for CO2 adsorption and separation.
