Abstract

The high amount of surfactant needed to formulate a bicontinuous microemulsion is a limiting factor for industrial usage of these systems. Commercially available triblock copolymers can be obtained in high amounts. Here, we show the influence of size and composition of different poly(ethyleneoxide)-poly(propyleneoxide)-poly(ethyleneoxide) triblock copolymer surfactants (Pluronics) on a technical grade sugar surfactant microemulsion. The so-called efficiency boosting can also be realized in such technical grade systems. The resulting efficiency boosting is studied systematically with regard to the impact of the polymer size and the composition of the system.

Kurzfassung

Häufig steht der industriellen Nutzung von Mikroemulsionen der hohe Bedarf an Tensid im Wege, der zur Ausbildung stabiler bikontinuierlicher Mikroemulsionen notwendig ist. Kommerziell erhältliche Triblockcopolymere stehen in großen Mengen zur Verfügung. In dieser Arbeit wird der Einfluss verschiedener Pluronic Triblockcopolymere auf das Phasenverhalten einer auf technischen Zuckertensiden basierenden Mikroemulsion gezeigt. In solchen technischen Systemen kann eine sog. Effizienzsteigerung erzielt werden. Die auftretende Effizienzsteigerung der Tenside wird systematisch auf den Einfluss der Polymergröße und Zusammensetzung des Systems hin untersucht.

Sebastian Hoehn studied chemistry and received his diploma from Friedrich Alexander University Erlangen-Nürnberg in 2009. Also in 2009 he started to work on his PhD thesis in the Hellweg group at Bayreuth University.

Christoph Schulreich studied chemistry and biology to become a teacher for secondary schools and received his first degree from Bayreuth University in 2011. In 2011 he started to work on his PhD thesis in the Hellweg group at Bielefeld University.

Thomas Hellweg received his diploma in chemistry from Bielefeld University in 1991 and finished his PhD in 1995 at the same university in the group of T. Dorfmüller. From 1996 to 1998 he was a postdoctoral fellow at the CRPP in Bordeaux in the groups of D. Langevin and D. Roux. In 1998 he started his habilitation at the TU Chemnitz in the physics department. In 2001 he moved to the Technical University of Berlin, where he finished his habilitation in 2005 at the Iwan-N.-Stranski-Laboratory. From 2007 to 2010 he has been professor for physical and colloid chemistry at the University of Bayreuth. Since October 2010 he has the chair for physical and biophysical chemistry at Bielefeld University. He is elected member and vice-chairman of the German committee for neutron research.
