Abstract

We studied a mixture of C12E5 microemulsion with an end-capped hydrophobically modified polymer (C12–PEO–C12). The end-capped polymer adsorbed on the core of the microemulsion, changed the bending properties of the interface and connected two nearby droplets. The core size and width of the structure factor of the microemulsion decreased upon adding the end-capped polymer. For all polymer concentrations, two relaxational modes corresponding to different diffusion coefficients were observed. The fast and slow diffusion coefficients showed a repulsive and an attractive interaction, respectively. The results of both small-angle x-ray scattering and dynamic light scattering suggested that fast relaxation is affected by size reduction and increasing the repulsive interaction between droplets.
