Poly [cyclotriphosphazene-co-(4, 4-sulfonyldiphenol)] microspheres grafted by water-soluble chitosan (PZSMS-g-Cs) were successfully prepared via a facile strategy. The water-soluble chitosan, which has low polymerization degree and narrow molecular weight distribution, was prepared by degradation from common macromolecular chitosan. The morphology and structure of PZSMS-g-Cs were characterized by SEM and TEM. The successful fabrication of PZSMS-g-Cs was confirmed by FTIR. The product PZSMS-g-Cs was found to have good water soluble property. The paper presents a simple, economic and efficient route to preparing functional hybrid inorganic-organic microspheres with good water soluble property.
