Preparation of Composite Hollow Microspheres on Gelatin Spheres as Templates
Source abstract
Abstract
The gelatin/SiO2/PAH composite microspheres using gelatin spheres as templates were fabricated by layer-by-layer self-assembly. Templates were removed by dissolving in hot water and the hollow SiO2/PAH microspheres were produced. Samples were characterized by ζ- potential, TEM, IR, TG, etc. measurements. The results showed that SiO2/PAH was assembled effectively on gelatin spheres and formed core-shell structure, and hollow structure was obtained by removing gelatin. In the process of dissolving templates, slow-releasing effect of hollow microspheres was found by the determination of amino acids from the hydrolyzed gelatin.
