By using the positive charged polystyrene (PS) microsphere as template, mono-disperse amino-(-NH(2)) functionalized hollow silica microspheres (HSMS-NH(2)) with ~1310 nm in diameter and uniform shells were successfully prepared with a modified sol-gel process. The amino functionalized silica were coated on the PS microspheres via ammonia catalysis, co-hydrolysis and condensation of TEOS and APTES, and then the PS templates were selectively dissolved in THF solution to form the functional hollow… CONTINUE READING
