Biomimetic morphogenesis of micropottery: helical coiling of mesostructured silica nanofibers†
نویسندگان
چکیده
Biomimetic morphogenesis of sophisticated mesostructured silica micropottery with a novel 3D hierarchically ordered structure and diverse morphologies was realized by hydrolyzing tetraethylsiloxane (TEOS) in concentrated HNO3 solutions containing cetyltrimethylammonium bromide (CTAB). It was proposed that the unique micropottery was self-organized by helical coiling of hexagonally ordered mesostructured silica nanofibers with the assistance of the NO3 counterion, which is amazingly reminiscent of the manufacture of pottery vessels by wheel shaping in ancient Oriental Asia. The observed self-organization of the mesostructured silica micropottery may open new avenues towards the microfabrication of advanced materials with hierarchical 3D architectures.

Seeding-growth of helical mesoporous silica nanofibers templated by achiral cationic surfactant.
Helical mesoporous silica nanofibers with parallel nanochannels were synthesized in high yield via a novel seeding-growth method by using the achiral cationic surfactant cetyltrimethylammonium bromide (CTAB) as template without auxiliary additives. A general entropy-driven model taking into account the icelike structure water due to the hydrophobic effect was proposed to explain the formation o...
متن کاملRapid synthesis of polymer-silica hybrid nanofibers by biomimetic mineralization
Biomimetic formation of silica from polyamines such as poly(ethylene imine) (PEI), inspired by the proteins found in diatoms and sponges, has been actively investigated recently as a potential route to silica formation compared to the conventional sol–gel process. We report silica formation onto nanofibers of PEI blended with poly(vinyl pyrrolidone) (PVP) obtained via electrospinning of their 5...
متن کاملSyntheses of Mesostructured Silica Films Containing Conjugated Polymers from Tetrahydrofuran-Water Solutions
Co-self-assembly of mesostructured silica films from solutions of tetrahydrofuran (THF) and water, silica precursor species, and structure-directing Pluronic P123 block-copolymer molecules is reported with and without conjugated polymer guest species. The solution-phase behavior of the ternary THF-water-P123 system guided the selection of nonequilibrium synthesis conditions that allowed highly ...
متن کاملComposite mesostructures by nano-confinement.
In a physically confined environment, interfacial interactions, symmetry breaking, structural frustration and confinement-induced entropy loss can play dominant roles in determining molecular organization. Here we present a systematic study of the confined assembly of silica-surfactant composite mesostructures within cylindrical nanochannels of varying diameters. Using exactly the same precurso...
متن کاملChirality control of self-assembled achiral nanofibers using amines in their solid state.
Although there are numerous examples of helical and spiral conformations in nature, including plant tendrils, snail shells, and even collagen, the occurrence of supramolecular systems that are able to reversibly undergo solid-to-solid helical transformation based on environmental chiral triggers is rare. In this work, we present a supramolecular, non-helical nanofiber which shows a distinct hel...
