pH responsive Janus polymeric nanosheets

Ion-triggered calcium hydroxide microcapsules for enhanced corrosion resistance of steel bars

“…MA is preferentially absorbed onto the calcium hydroxide particle surface via hydrogen bonding between MA and hydroxyl group of calcium hydroxide. Since MA is not self-polymerizable, and MA can be copolymerized with DVB, 31 the shell composed of crosslinked PILs and MA is generated onto the surface of the calcium hydroxide particle by free radical polymerization. After being encapsulated with polymer shell, the surface of the microcapsules became smooth ( Fig.…”

Design, Synthesis, and Application of Anisotropic Janus Particles

“…Further, we proposed a similar facile method to prepare pH-responsive Janus sheets by polymerization at the oil-water interface. The stability of emulsions stabilized by such Janus sheets can be easily achieved by maintaining the pH value [47]. The other important strategy of preparing Janus sheets/disks is to dismantle the self-assembled copolymer bulk (Fig.…”

“Indanonalkene” Photoluminescence Platform: Application in Real-Time Tracking the Synthesis, Remodeling, and Degradation of Soft Materials

“…7−12 There are still many challenges for the exploration of new stimuliresponsive polymers, as the regulation of their mechanical properties has been constrained by certain chemical functional group interchanges or limited structural/morphological changes. 13−15 Moreover, synthesis, fabrication, or the reforming for stimuli-responsive materials usually results in macroscopic changes but are optically invisible, 16−18 e.g., a pH, 19 photo, 14 thermal, 20 or chemical trigger, 21 due to the nonluminescent indicator generated. Consequently, the precise control or accurate information delivery through changing the properties of the material remains underexplored.…”
