In general, the volume ratio between the hydrophobic and hydrophilic parts of the amphiphile is important to show lyotropic phases with lamellar, micellar or vesicular structures. In the case of nonionic polyethylene glycol monoalkyl ether (CmEn: m is the alkyl carbon number, and n is the number of the oxyethylene units), the ratio m/n determines the phase transition behaviors; hyperswollen lyotropic lamellar phases appear when m/n is in a certain range (2.4〜4). We examined whether aqueous C12E6 solution, which does not show hyperswollen lamellar phases intrinsically, added toluene shows a hyperswollen lamellar phase. Instead of toluene, the addition of styrene to a C12E6 solution also induces a hyperswollen lamellar phase. Thus, polymer and carbon nanosheets from the styrene can be synthesized in the hyperswollen lamellar phase. Furthermore, we found that the temperature range of the hyperswollen lamellar phase can be controlled by the addition of glycerol.
