摘要: Surface dilational rheological behavior and foam stability of starch/surfactant mixed solutions were studied at different starch concentrations and constant surfactant concentration. The results show that dilational viscoelasticity modulus, dilational elasticity modulus and dilational viscosity modulus increase with the concentration of starch particles. Foam stability increaseswith dilational viscoelasticity. Foamstrength also increases with starch concentration. Starch particles play a positive effect on foamstability and dilational viscoelasticity and the effect becomesmore significant as drainage proceeds. Film pictures indicate that the film with 20% (by mass) starch particles is thicker than that without starch. Starch particles gather in Plateau border and resist drainage, making the foammore stable.
