1 Jul 2004 | Journal: | Europhys. Lett. 66, pp888-894 (2004) DOI: 10.1209/epl/i2003-10260-6 | Subject: | Soft Condensed Matter | cond-mat.soft | Abstract: | We demonstrate the possibility of a stable equilibrium multi-lamellar (``onion’’) phase in pure lamellar systems (no excess solvent) due to a sufficiently negative Gaussian curvature modulus. The onion phase is stabilized by non-linear elastic moduli coupled to a polydisperse size distribution (Apollonian packing) to allow space-filling without appreciable elastic distortion. This model is compared to experiments on copolymer-decorated lamellar surfactant systems, with reasonable qualitative agreement. | Source: | arXiv, cond-mat/0407021 | Services: | Forum | Review | PDF | Favorites |
