摘要: Abstract The foam properties of Tween 20 and BSA systems in Tris–HCl buffer solution were investigated by nitrogen-blowing method on a Foamscan. foamability 20/BSA is obviously better than that individual system. foams stabilized drained slower with or without BSA. stability enhanced an addition optimal ratio to determined for the most stable foams. Surface dilational rheological results indicate surface elasticity dominates adsorbed layer it increased presence variation accords increase concentration. It can be concluded corresponding stability.
