Substrate-directed formation of calcium carbonate fibres

Polymerization-induced self-assembly of block copolymer nanoparticles via RAFT non-aqueous dispersion polymerization

“…This is because strong lateral electrostatic repulsion between neighboring polyelectrolytic chains impedes in situ self-assembly [24,72]. In collaboration with Meldrum and co-workers, we have recently shown that anionic PMAA x -PBzMA y nano-objects can be efficiently occluded within single crystals of calcite, leading to a series of novel organic-inorganic nanocomposites that exhibit superior mechanical properties to that of calcite alone [73,74]. Additionally, anionic PMAA 71 -PBzMA 200 vesicles were successfully coated with cationic 12 nm alumina-coated silica particles (Ludox CL) to form 'armoured' vesicles [67].…”

“…More recently, Zhang et al [57] reported the formation of 'multi-shelled' vesicles when targeting highly asymmetric (e.g. P4VP 73 -PS 9400 ) diblock copolymers in methanol (Figure 4e). These formulations indicate the complexity of block copolymer morphologies that can be achieved when utilizing PISA formulations in methanol.…”

PMA‐b‐PAA‐controlled synthesis of one‐dimensional CaCO3 superstructures

“…To the best of our knowledge, only one report exists of a DHBC supporting the formation of onedimensional CaCO 3 fibres comprised of nanoscale units or building blocks [17]. In the paper, one-dimensional CaCO 3 crystals with morphological complexity were prepared by a simple gas-liquid diffusion approach using PMA-b-PAA copolymer as an effective template.…”

Anisotropic nanowire growth via a self-confined amorphous template process: A reconsideration on the role of amorphous calcium carbonate

“…Moreover, ACC emerges frequently in the formation of CaCO 3 fibers [24,28,34,38,39]. Accordingly, in immature nanowires, we found an ACC layer (Figs.…”

“…The stabilization and transformation of the ACC phase has been studied [31][32][33][34][35][36][37][38][39][40][41]. Gower et al proposed a so-called polymer induced liquid precursor (PILP) process which has been found in many mineralization processes where polymers were used as stabilizers [10,31].…”
