Synthesis and Characterization of pH-Responsive Organic–Inorganic Hybrid Material with Excellent Catalytic Activity

Palladium nanoparticles-anchored dual-responsive SBA-15-PNIPAM/PMAA nanoreactor: a novel heterogeneous catalyst for a green Suzuki–Miyaura cross-coupling reaction

“…When the pH exceeds the pKa value (pH 4), the COOH group in the methacrylic acid becomes protonated, which further creates a repulsive force between them, resulting in the swelling of catalyst. 26,34 These results highlight the dual-responsive behaviour of the PdNPs-SBA-15-PNIPAM/PMAA catalyst.…”

Fabrication of NIPMAM based polymer microgel network assisted rhodium nanoparticles for reductive degradation of toxic azo dyes

“…By adding a surfactant (SDS) the correct stability and monodispersity of microgel particles are achieved. When the polymerization process is completed, the reaction solution is cooled to ambient temperature to swell the microgel particles [ 25 ].…”

A review on Ag nanoparticles fabricated in microgels

“…HDD of increases owing to electrostatic repulsion between like-charged components within the microgel structure. For example, Ashraf et al 79 have synthesized Ag nanoparticles encapsulated poly( N -isopropylmethacrylamide-methacrylic acid) Ag–P(NIMA-MAcA) hybrid microgels. They studied the pH effects on both microgels and hybrid microgels by varying the pH from 2 to 12.…”
