Controllable synthesis of CuS–P(AM-co-MAA) composite microspheres with patterned surface structures

Synthesis and properties of silver nanoparticles in chitosan‐based thermosensitive semi‐interpenetrating hydrogels

“…Generally, metal nanoparticles tend to agglomerate due to high active surface area. To stabilize the nanoparticles, various polymeric agents including polymeric micelles, dendrimers, latex particles, microgels, and hydrogels are used 6–8. Among of these supports, hydrogels are extensively used in situ synthesis of smaller size metal nanoparticles due to their three‐dimensional networks and good biocompatibility.…”

Formation mechanism of zigzag patterned P(NIPAM-co-AA)/CuS composite microspheres by in situ biomimetic mineralization for morphology modulation

“…Additionally, the unswollen core constrains the swelling region, and thus leads to pattern formation in the wetted region. Although the composition of our composite microspheres with pattern is different from the hydrogel mentioned above, based on the results we reported, [21][22][23][24][25][26][27]32,33 the patterned structures of the composite microspheres made by in situ deposition of inorganic ingredients on the microgel were seemingly related to network distortion of the microgel surface instead of the crystal appearance of the inorganic components. So, in this paper, the formation mechanism on the patterned surface of the P(NIPAMco-AA)/CuS composite microspheres was mainly concentrated to research on factors related to the deformation of the P(NIPAMco-AA) gel networks as CuS in situ formed.…”

“…Recently, our group proposed a microgel template mineralization approach and developed innovated studies in the preparation of different composite microspheres by using the microgel template technique. Previous studies reported [21][22][23][24][25][26][27] the different pattern morphologies formed by the deposition of different metal suldes or metallic oxide on the microgel template. It was found that the surface morphology is affected by varying the composition of the template, 21,22 the deposited inorganic ingredient, 23,24 structure of surfactants, 25 the kinds of inorganic-salts 22,26 and sulde source.…”

“…It was found that the surface morphology is affected by varying the composition of the template, 21,22 the deposited inorganic ingredient, 23,24 structure of surfactants, 25 the kinds of inorganic-salts 22,26 and sulde source. 27 The previous papers mainly focused on the interesting results of various patterned surface structures of metal sulde deposition on the hydrogel surface, 21,22 whereas the formation mechanism is only a speculation, and these speculations are not reasonable to some extent. For example, as described in the literature, 21 the isopropyl groups of the copolymer, P(NIPAM-co-AA) near the interface might extend to the continuous phase due to their hydrophobic nature.…”

Synthetic Strategies for Polymer Particles with Surface Concavities

“…Surface‐wrinkled (or crumpled) particles that have significantly enlarged surface areas widely exist in the nature (e.g., pollens, plant seeds, microorganisms, etc.). [ 177–180 ] Inspired by them, surface‐wrinkled polymer particles have been investigated both theoretically [ 181,182 ] and experimentally [ 56,57,139,183–226 ] in recent years. The synthesis of surface‐wrinkled polymer particles can also be conducted by polymerization or post‐treatment methods, as discussed below.…”
