摘要: summary We have describe three experimental methods using drops for the measurement of different aspects interactions between emulsion drops. The LSFA allows measurements capillary force and drop deformation asized as it is pressed up to an oil-water interface. forces deformations are well described by theory no adjustable parameters. can also be used determine disjoining pressure isotherms film thickness 5 - 100 nm andvalues in range 2000 Pa. contact angle method developed Princen at al. interaction energy per unit area adhesive, non-coalescing drops.It has been successfully characterise a specific, salt induced but could extended quantify other forces. barrier rupture coalescence. techniques yield complementary information offer future promise gain increased quantitative detailed understanding their role determining stability.
