采用伏安法和恒电位极化法研究了不同离子类型的全氟表面活性剂（包括烃链表面活性剂CTAB）对锌电化学行为的影响。结果表明，这些表面活性剂可作为汞的替代品，用于降低锌电池的腐蚀。实验还表明，在这些表面活性剂存在下，锌酸盐电解液中锌的沉积可得到一定程度的改善。电沉积锌的形态表明，这些表面活性剂可以使沉积物更加均匀、致密，从而减少枝晶生长。FC-170 C和CTAB被发现是最有效的抑制剂。
The effects of different ionic types of perfluorosurfactants (including hydrocarbon chain surfactant CTAB) on the electrochemistry behavior of zinc have been examined using voltammetric and potentiostatic polarization techniques. The results show that these surfactants can be used as substitute of mercury for decreasing the corrosion in zinc batteries. It is also shown that the deposition of zinc from zincate electrolyte in the presence of these surfactants can be improved to some extent. The morphology of the electrodeposited zinc shows that these surfactants can bring about more uniform and compact deposits and, thereby, reduce dendritic growth. FC-170C and CTAB are found to be the most effective inhibitors.
