摘　　要：研究了几种表面活性剂的物化性能(平衡表面张力、动态表面张力等)与润湿性能之间的相关性。结果表明:良好的动态表面张力是优异润湿性能的必要条件,而非充要条件;适当提高疏水基的支链化度可改善动态表面张力,进而提高润湿性能。The relationship between physicochemical properties (equilibrium surface tension,dynamic surface tension,etc.) and wettability of several surfactants was studied.The results showed that good dynamic surface tension was a necessary condition for excellent wettability,but not a necessary and sufficient condition.Proper improvement of branching degree of hydrophobic groups could improve dynamic surface tension and wettability.
