PRECISELY-SHAPED POROUS PARTICLES |
摘要 |
<p>Precisely-shaped composites and methods for making these composites are disclosed. The method of this disclosure comprises introducing a precursor composition onto a production tool having at least one continuous surface and a plurality of cavities so as to fill at least a portion of the cavities with the precursor composition and wherein the precursor composition, upon curing, forms a composition having a shape corresponding to the cavities thereby resulting in a plurality of discrete, precisely-shaped particles having a porosity comprising one of the following: (a) 10 m2/g or greater or (b) 5 kdalton or greater. The precisely-shaped particles have at least one essentially flat side. The precisely-shaped particles can be confined in a vessel and used for chromatographic applications.</p> |
