    Project supported by the Key Project of the Ministry of Education of China (No.02128) and the National Natural Science Foundation of China (No.20043002).

摘要: The chemical composition, morphology of the particles of positively charged layered double hydroxides (LDHs) were studied by ICP, Mastersizer, TEM.The preliminary results indicated that with adding LDHs to 1% laponite dispersion the yield stress oflaponite/LDHs mixed dispersions increased at first, then decreased dramatically to a minimum, and the yield stress rose again when LDHs increased further.
