英文摘要	The poly(AM-AA)/MMT composites hydrogel particles coated alginate were successfully prepared by the method of microcapsule technology. The obtained particles were spherical, smooth-surfaced, hollow-structural and non-aggregated with a diameter of 1.5 similar to 2.0 mm. The diameters of particles can be controlled and depended on the size of initial drop on the concentration of Al(NO3)(3), SA(Sodium alginate) and their time of solidification, as well as on the concentration and size of core materials. The water-absorbent rate of coated plugging agent was remarkable in different conditions and fell based on the sequence of fax (f(a1): tap water at 25 degrees C; f(a2): physiological saline solution at 25 degrees C; f(a3): tap water at 45 degrees C; f(a4): physiological saline solution at 45 degrees C). The particles are stable for 15 days in the medium of pH ranged from 3 to 6, while the particles are degraded in simulated fluid with pH of 1, 2, 11 or 12.
