Multi-stimuli-responsive bottlebrush-colloid Janus nanoparticles toward emulsion interfacial manipulation and catalysis

Abstract

A general approach is proposed to large scale synthesize multi-stimuli responsive bottlebrush-colloid Janus nanoparticles (JNPs) by preferentially tuning the composition of a single chain nanoparticle (SCNP). The starting SCNP is...

Thermoresponsive Reversible Unimer Micelles of Amphiphilic Fluorinated Copolymers

“…Therefore, the field has experienced remarkable growth in the last two decades. [4][5][6] Practical application of such artificial single-chain nanostructures may be enormous, and several examples are already present in the scientific literature, especially in the fields of, but not limited to, catalytic nanoreactors, [7,8] nanoprobes, [9] environmental remediation, [10,11] vectors for contrast agents, [12][13][14] encapsulation and delivery carriers, [15][16][17][18] surfactants, [19,20] and anti(bio)fouling systems. [21] Recent advances in polymer chemistry resulted in considerable progress toward the synthesis of artificial polymers with reproducible self-folding ability via elective point folding methods and repeat unit folding routes.…”

Temperature-Sensitive Janus Particles PEG/SiO2/PNIPAM-PEA: Applications in Foam Stabilization and Defoaming

“…These materials possess the capability of autonomously recognizing changes in the surrounding environment, thereby enabling precise control and functional modulation. By incorporating stimuli-responsive materials into Janus particles, these particles acquire the ability to undergo reversible responses to specific stimuli such as variations in temperature, − pH levels, ,, light, − and magnetism. , This characteristic of intelligent regulation and targeted functionality has undeniably paved the way for novel applications of Janus particles across a wide range of fields.…”

Single Chain Nanoparticles in Catalysis

“…Only a few examples exist where catalytic properties are controlled via changes in the SCNP morphology. [39] Controllable SCNP catalysis via on demand reversible structural changes not only entails the possibility of varying catalytic rates, but also enables tuneable substrate selectivity by changing the morphology of the catalytic site, allowing certain substrates while excluding others. [40] It is therefore of critical importance to determine the internal morphology of SCNPs for catalysis in order to elucidate how the morphological changes in SCNPs affect their catalytic activity.…”
