Abstract: Nanoflake silver powder is synthesized with silver nitrate solution as the precursor by chemical reduction method in two steps.The influence of dodecyl trimethyl ammonium bromide dosage,silver nitrate solution dosage and adsorbent types on nanoflake silver powder is investigated in experiments.The results show that when the dodecyl trimethyl ammonium bromide dosage is 0.000 5 g,low-concentration silver nitrate solution dosage is 2 mL,and with the synergy of CTAB,PVP and citric acid adsorbents,the nanoflake silver powder synthesized has evenly distributed particles and better dispersity.
