Summary: The use of cationic hyperbranched poly (amido-amine)s as macromonomers for nanofiltration membrane fabrication allows for modulation of outer voids between molecules to enhance permeability and selectivity. The resultant membrane demonstrates ultrahigh retention for molecules with high molecular weights or positive charges, achieving molecular-level selectivity for different types of molecules.

Summary: In this study, biogenic silica (BSi) was extracted from rice husks and functionalized using three different molecular structure amine groups. The functionalized silica was combined with Pebax-1657 to form mixed matrix membranes (MMMs), which showed significantly improved CO2 permeability and CO2/N2 selectivity compared to Robeson's upper bound 2008. Among them, Pebax/BSi-MAPS-10 was the most reliable membrane. These findings suggest that amine functionalized BSi has great potential for CO2/N2 separation in industrial applications.

Summary: In this study, a thermo-responsive microgel based on hyperbranched polysiloxane with aggregation induced emission (AIE) was reported for the first time. The microgel showed enhanced thermo-response and AIE-active fluorescence with increasing temperature. The drug loading and release properties of the microgel were investigated using Luteolin as a model drug. The results demonstrated that the fluorescence emission of the microgel could be adjusted by environmental temperature or the content of Luteolin, making it easy to detect the drug loading or release properties.

Summary: This study constructed light-responsive poly(aryl ether ketone) (PAEK) hybrid structures with enhanced strength and wavelength-selective responses. These structures exhibited programmable multistage deformations under light irradiations of different wavelengths. Additionally, man and flower smart structures were designed to demonstrate wavelength-selective responsive motions, which could be tuned by manipulating the arrangement of photosensitive components and light irradiation wavelengths. The wavelength-selective shape memory hybrid structures have potential applications in the fields of soft robots, smart actuators, and deformed devices.

Summary: Graphene oxide (GO) membranes can be used for water treatment to remove organic molecules. However, the effect of pH on GO's properties leads to poor removal of positively charged model compounds. In this study, pH-responsive polymers were used to modify GO membranes, resulting in improved removal performance, water permeance, and long-term stability.

Summary: This study describes a novel and facile approach to graft hyperbranched poly(thiol ether-ester) onto multi-walled carbon nanotubes (MWCNTs) using thiol-yne click chemistry. Through various techniques, the covalent grafting between the polymeric chains and the carbon nanotubes was confirmed. The grafting significantly improved the dispersion stability of the MWCNTs in water, and the resulting MWCNTs-HPTEE showed oxidation responsiveness due to the presence of oxidizable thioether groups.

Summary: This study reported the preparation and systematic investigation of cross-linked polyurethane-epoxy (PU-EP) polymer systems. The PU-EP polymers were synthesized by reacting NCO-terminated PU prepolymers with diglycidyl ether of bisphenol A (DGEBA)-amine cooligomers. The addition of furfurylamine (FA) or ethanolamine (EA) resulted in the oligomerization of DGEBA and the formation of DGEBA-amine cooligomers. The cross-linking was achieved by adding the DGEBA-amine cooligomer to the PU prepolymers, forming urethane bonds as netpoints. The presence of furfurylamine allowed for the formation of additional thermoreversible bonds, leading to shape memory behavior in the PU-EP networks.
