The Self-Assembly of an Amphiphilic Block Copolymer: A Dissipative Particle Dynamics Study
-
S. G. Schulz
Abstract
The self-assembly of a poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethylene oxide) blockcopolymer (EO13PO30EO13) in the presence of water was investigated. The phases have been studied with the mesoscopic simulation technique Dissipative Particle Dynamics (DPD). The micellar, hexagonal, lamellar, bicontinuous and inverse micellar phase have been identified with this method and showed remarkable agreement with the experimental phase behavior. This work showed that the Dissipative Particle Dynamics simulations are also suitable for complicated polymer systems such as the EO13PO30EO13 triblock copolymer.
Kurzfassung
Die Selbstanordnung eines Poly(Ethylenoxid)-block-Poly(Propylenoxid)-block-Poly(Ethylenoxid) Copolymers (EO13PO30EO13) in Anwesenheit von Wasser wurde untersucht. Die Phasen sind mit der Dissipative Partikel Dynamik (DPD), einer mesoskopischen Simulationstechnik, untersucht worden. Die mizellare, hexagonale, lamellare, bikontinuierliche und inversmizellare Phase konnten mit dieser Methode identifiziert werden und zeigten bemerkenswerte Übereinstimmung mit dem experimentellen Phasenverhalten. Diese Arbeit zeigte, dass die Dissipative Partikel Dynamik Simulationen auch auf schwierige Polymer Systeme wie das Triblockcopolymer EO13PO30EO13 anwendbar sind.
