Abstract
We study the confinement of polysoaps in lyotropic smectic ( ${L}_{\ensuremath{\alpha}}$) and sponge ( ${L}_{3}$) solutions of the nonionic surfactant pentaethylene glycol dodecyl ether ( ${\mathrm{C}}_{12}{\mathrm{EO}}_{5}$). The polysoap is a hydrophobically modified polymer with $n$-tetradecyl sidegroups randomly grafted to a polyacrylate backbone. Without the hydrophobic side chains the backbone polymer cannot be embedded into the intermembrane space, but confinement is achieved for a polysoap with as low as 1% of grafted groups. We measure by small angle x-ray and neutron scattering an increase of the bending rigidity of the lamellar membranes as a function of polysoap concentration.
