Triblock-Copolymer-Directed Syntheses of Large-Pore Mesoporous Silica Fibers
Abstract
Mesoporous silica fibers with accessible, highly ordered large periodic pores are directly drawn from a highly viscous surfactant/silicate solution. Poly(ethylene oxide)-b-poly(propylene oxide)-b-poly(ethylene oxide) triblock copolymers are used as the structure-directing agents under acidic conditions during the syntheses. These fibers have uniform exterior diameters of submicron to several hundred micron and no apparent limit on aspect ratios. They are made up of either supercage arrays or 2-dimensional channel arrays with pore sizes as large as 63 Å.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
