Development of recoverable and recyclable Fe3O4‐supported organocatalysts for ring‐opening polymerization

“…Clearly, this Fe 3 O 4 encapsulation occurred during the copolymerization of hexachlorocyclotriphosphazene and 4,4′‐sulfonyldiphenol. It might be worth noting that Ning et al recently reported that polymeric or inorganic nanoparticles with proper surface functionality could also be efficiently incorporated into inorganic crystal hosts 53–57 . X‐ray diffraction (XRD) results showed that Fe 3 O 4 nanoparticles and Fe 3 O 4 @PZS@HMP 1 exhibited same pattern (ESI†, Figure S1d).…”

“…It might be worth noting that Ning et al recently reported that polymeric or inorganic nanoparticles with proper surface functionality could also be efficiently incorporated into inorganic crystal hosts. [53][54][55][56][57] X-ray diffraction (XRD) results showed that Fe 3 O 4 nanoparticles and Fe 3 O 4 @PZS@HMP 1 exhibited same pattern (ESI †, Figure S1d). The synthesized Fe 3 O 4 @PZS@HMP 1 particles can be dispersed well in tetrahydrofuran, toluene, dichloromethane, and chloroform.…”

Polymerizations by RAFT: Developments of the Technique and Its Application in the Synthesis of Tailored (Co)polymers

“…Up to the moment of preparing this article there have been more than 20 review articles published on RAFT‐mediated PISA, looking into different aspects of the technique. [ 72,76–85 ] Only in 2020 (by September) there have been more than 100 papers published on the topic. Here we focus mainly on the latest and the most outstanding reports on RAFT‐PISA prepared nano‐objects.…”

“…Polymers prepared by RAFT have been used in many different fields, notably in preparation of biomaterials (implants, scaffolds, coatings, drug, gene delivery, etc. ), [ 226–230 ] sensing and detection, [ 231,232 ] coatings and patterning, [ 233–235 ] electronics, [236] nanocomposite, [ 235,237–240 ] and vitrimers. [ 241 ] One of the most recent and emerging applications of polymers and nanoparticles prepared by RAFT is membranes for separation.…”

Exerting Spatial Control During Nanoparticle Occlusion within Calcite Crystals

“…At first sight, nanoparticle occlusion within inorganic crystals appears to be highly counter-intuitive because crystallization is normally considered to involve expulsion of impurities,r ather than their incorporation. Nevertheless, efficient nanoparticle occlusion can occur under optimized conditions, [1] producing nanocomposite crystals that differ significantly from those hybrid materials produced via conventional chemical or mechanical mixing. [2] In some cases, such nanocomposite crystals can exhibit enhanced hardness and toughness compared to their geological counterparts.…”
