Structural Control of Microemulsion Droplets by Multiple-bridging Amphiphilic Copolymers

DOI

Microemulsions are thermodynamically stable, low-viscous liquid mixtures of oil and water stabilised by the presence of surfactant, structurally composed of oil-in-water (O/W) or water-in-oil (W/O) droplets, or bi-continuous. Their low viscosity is an essential drawback preventing many applications. Better control over their viscosity has consequently a high potential. For the case of droplet microemulsions, an intuitive option is to bridge droplets by amphiphilic polymers. This concept works well for the case of O/W microemulsion droplets and end-capped PEO [Gradzielski 1993]. Interconnecting droplets leads to a substantial increase in viscosity when exceeding an effective percolation concentration of droplets and polymer [Gradzielski 1993, Filali 2001]. The effect of polymers offering multiple arms for highly bridged systems, so far unreported, shall be studied by SANS in detail.
