Effect of Polyacrylamide Hydrogels on Synthesis of Hollow Sodalite Spheres

Abstract:

Hollow sodalite spheres were prepared in water-soluble polymer polyacrylamide hydrogels (PAM) which were used as "soft template". The samples were characterized by XRD and SEM. The influence of the contents of initiator (ammonium persulfate) and crosslinker (N,N’-methylene-bis-acrylamide) on the size and morphology of hollow sodalite spheres was investigated. The results showed that the pore sizes of hollow sodalite spheres significantly decreased and the shell thicknesses thickened as the amount of initiator increased. The amount of MBAM affected the crystallization of sodalite, stacked arrangement and hollow structure. When the amounts range of MBAM was 0.8%-1.6%, hollow sodalite spheres were non-friable and smaller than the others, and their arrangement was uniform and orderly.
