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