1. A method for preparing a material comprising of a continuous aqueous phase and a dispersed phase, dispersed in the form of droplets containing a phospholipid and a surfactant having the following formula (I):
(L1-X1—H1—Y1)v-G-(Y2—H2—X2-L2)w   (I),wherein:
L1 and L2 independently represent lipophilic groups, X1, X2, Y1, Y2 and G independently represent a linking group, H1 and H2 independently represent hydrophilic groups including a polyalkoxylated chain, v and w are independently an integer from 1 to 8,the said method comprising bringing into contact:
an emulsion 1 comprising a continuous aqueous phase and a dispersed phase, dispersed in the form of droplets containing an phospholipid and a surfactant having the following formula (LI):
L1-X1—H1—Y1-G1   (LI),with an emulsion 2 comprising a continuous aqueous phase and a dispersed phase, dispersed in the form of droplets containing an phospholipid and a surfactant having the following formula (LII):
G2-Y2—H2—X2-L2   (LII)where G1 and G2 are groups that are capable of reacting in order to form the G group, under conditions that allow for the reaction of the surfactants having the formulas (LI) and (LII) in order to form the surfactant having the formula (I), whereby covalent bonds between the droplets of the dispersed phase are formed.
