“…Among various polymers utilized for corrosive gas partition, the polyvinyl amine (PVAm) has the most promising potential. Because of the presence of large amine gathering and high level of hydrophilicity, it provides high permeability and selectivity for CO 2 [104]. ermodynamic properties of polymers assume a crucial part in the separation performance of membranes.…”

“…Methods for reducing membrane wettability include using hydrophobic membranes, a dense surface layer composite membrane, selecting high surface tension liquids, and operating at a pressure lower than the liquid inlet pressure [126]. Saeed et al [104] in their research improve the water affinity and mechanical properties of PVAm membranes to enhance CO 2 separation at pressures that are moderately high. A PVAm matrix was incorporated with CNC in order to get results that are beneficial.…”

The adoption of nanodoped membranes in the areas of gas stream separation, water, and wastewater treatments due to the physical and operational advantages of such membranes has significantly increased. The literature has shown that the surface structure and physicochemical properties of nanodoped membranes contribute significantly to the interaction and rejection characteristics when compared to bare membranes. This study reviews the recent developments on nanodoped membranes, and their hybrids for carbon capture and gas separation operations. Features such as the nanoparticles/materials and hybrids used for membrane doping and the effect of physicochemical properties and water vapour in nanodoped membrane performance for carbon capture are discussed. The highlights of this review show that nanodoped membrane is a facile modification technique which improves the membrane performance in most cases and holds a great potential for carbon capture. Membrane module design and material, thickness, structure, and configuration were identified as key factors that contribute directly, to nanodoped membrane performance. This study also affirms that the three core parameters satisfied before turning a microporous material into a membrane are as follows: high permeability and selectivity, ease of fabrication, and robust structure. From the findings, it is also observed that the application of smart models and knowledge-based systems have not been extensively studied in nanoparticle-/material-doped membranes. More studies are encouraged because technical improvements are needed in order to achieve high performance of carbon capture using nanodoped membranes, as well as improving their durability, permeability, and selectivity of the membrane.

Despite polylactide (PLA) representing one of the most promising biodegradable materials, its applications lag far behind owing to the disadvantages of inherent brittleness and flammability, which is challengeable to simultaneously overcome.In this work, a phosphorus-containing core-shell starch nanoparticle (FR-CSS) was synthesized via soap-free emulsion polymerization for concurrent improvement of toughness and flame retardancy of PLA. The results revealed that with the incorporation of 10 wt% FR-CSS, the elongation at break of PLA/10FR-CSS was prominently improved to 308% while the tensile strength was about 40.0 MPa. Particularly, the toughness of PLA/FR-CSS was as high as 108.2 MJ/m 3 , which was 48 times higher than that of neat PLA. Besides, the PLA/10FR-CSS exhibited improved flame retardancy with a UL-94 V-2 rating and a LOI value of 24.5%. These results established an integrated design strategy of incorporating phosphorus-containing core-shell nanoparticles to prepare PLA composites combined excellent toughness with enhanced flame retardancy, therefore broadening the application gallery of PLAs.

In this article, a novel method of microcapsule preparation was provided, that is, ethyl cellulose-glycerol tribenzoate microcapsule (EGM) was prepared using CO 2 /N 2 switchable hydrophilicity solvent(N, N-dimethylcyclohexylamine) combined with an emulsion method. Microcapsules were prepared and solvents were recovered by changing the properties of the solvent. The optimum preparation conditions of EGM were the materials ratio of 20%, the oil-water ratio of 4.5:5.5, emulsifier content of 2%, the Span80-Tween80 ratio of 1:3, and the core-shell ratio of 1. The morphology of EGM is spherical, and the particle size can be adjusted from 0.01 μm to 90 μm by controlling the agitation speed in the synthesis process. Surprisingly, the average yield(Y[%]) reached 95.36%, the effective content(W[%]) reached 41%, and the encapsulation rate(E[%]) reached 90.66% of EGM. The solvent recovery rate(SR[%]) of the first recovered is 96.37%. Significantly, this method not only provides a new idea for the preparation of microcapsules but also expands the application field of switchable hydrophilicity solvents, which makes it has great potential application value in the field of microcapsule preparation in the future.
