On the shapes of lamellar droplets in sponge phase

We present a qualitative study of the macroscopic properties of the interfa ce between the lamellar and the sponge phase and a brief account of the sha pe of droplets of lamellar phase in sponge phase. Similar to G, Friedel's " batonnets", but much simpler, those droplets are the result of a competitio n between interfacial tension, smectic elasticity and growth mechanisms.
