How to prevent flocculation is a universal problem in synthesis and application of nanoparticles. Because of high surface activity, nanoparticles tend to form large di-mension of aggregates with some loose contact interface. When solid particles are suspended in polyelectrolyte so-lution, polymer chains are adsorbed on the surface of par-ticles and they render to stabilize the corresponding parti-cles. The stabilizing property of polyelectrolytes is the reason for wide application in many fiel… 相似文献
