On the Shapes of Lamellar Droplets in Sponge Phase
Résumé
We present a qualitative study of the macroscopic properties of the interface between the lamellar and the sponge phase and a brief account of the shape of droplets of lamellar phase in sponge phase. Similar to G. Friedel's “bǎtonnets”, but much simpler, those droplets are the result of a competition between interfacial tension, smectic elasticity and growth mechanisms.
