“…2 Schematic illustration of the radial electron scattering length density distribution of a microemulsion droplet. The respective densities are r w ¼ 9.4 Â 10 À6 ÅÀ2 , r d ¼ 7.15 Â 10 À6 ÅÀ2 and r polar ¼ 2.39 Â 10 À5 ÅÀ2 (polar head group 31,38 ). The polar radius R polar ¼ R c + d is given by the radius of the water core R c and the polar shell thickness d ¼ 2.1 Å.…”

“…Both shrinking and growing of droplet sizes with increasing temperature have been found and discussed in terms of repulsive forces among the AOT head groups, clustering of droplets and concentration effects. 9,18,38,47,48 However, it is not simple to predict the droplet sizes since in eqn (3) the AOT surface area A AOT , the volume of the AOT head group n SO À 3 and Fits done with combined structure factor S(q) ¼ S(q) HS + S(q) L .…”

“…The interaction of polymers with micelles or microemulsions has been widely studied in the past, but these studies usually refer to soluble or partially soluble macromolecules as block copolymers. [76][77][78][79][80] Conversely, very few studies have addressed the action of o/w microemulsions on hydrophobic polymeric coatings.…”

Smart cleaning of cultural heritage: a new challenge for soft nanoscience

The search for innovative, smart and performing cleaning agents is one of the main issues of modern conservation science. Nanosciences do not only provide solutions to this scientific field in terms of new materials but also change radically the approach to problems and challenges. In this feature article we review the most innovative nanostructured systems developed in the last decade for the cleaning of artworks together with some noteworthy case studies. Micelles, microemulsions, thickened complex fluids, and responsive gels that constitute the new "cleaning palette" for modern conservators are here presented and critically analyzed. The development of these smart nanostructured systems requires the comprehension of their behavior and interactions with other materials down to the nanoscale. In the last section of this manuscript we report on the most recent results from a study about the mechanism of polymer removal from porous artifacts using nanofluids, such as micelles or microemulsions. The rules of classical detergency do not fully address the polymer removal mechanism and a schematic model of the process is proposed.

“…when amphiphilic triblock copolymers are used as cosurfactant. When the triblock copolymer is mainly dissolved in the internal phase, namely it is confined in a droplet, a droplet deformation may appear [19] which can lead to nematic microemulsion droplet phases [99]. Upon addition of a triblock copolymer which is mainly dissolved in the external phase, either decoration of single droplets (loops) or bridging into a transient network (arcs) may occur.…”

This contribution deals with a special class of soft matter systems called microemulsions. They are mixtures of oil and water stabilized with a surfactant. The stabilisation is achieved through the reduction of interfacial tension by the amphiphilic surfactant. They thus consist of oil and water phases separated by a surfactant layer. The nanoscopic structure of these phases, in particular that of spherical nano droplets, is analysed in this chapter. The impact of temperature and mixing ratio of the constituents is shown. The fascinating phenomenon of dynamic droplet percolation and aggregation near a temperature induced phase separation are discussed. Microemulsions provide an excellent model system for the investigation of confinement effects on molecules. Conversely these guest molecules modify structural and dynamical properties of the microemulsion. This may even lead to the formation of transient networks with short time gel-like and long time self-diffusion dynamics of droplets.
