摘要: The inclusion of a water-soluble polymer, poly(vinyl pyrrolidone) (PVP), into surface active film composition before application to the water leads formation dynamic duolayer; novel system. This duolayer shows improved viscosity over monolayer compound alone, while addition polymer maintains other properties such as evaporation control and equilibrium spreading pressure. Brewster Angle Microscopy that undergoes different mechanism upon compression, resultant pressure/area isotherm is at lower pressures indicating PVP present on these squeezed out subphase higher pressures. polymers form provides unique way produce defect-free tightly packed films associated with film. finding new knowledge for design potential applications in many areas.
