Journal ArticleDOI
Asymmetric superstructure formed in a block copolymer via phase separation
TL;DR: An innovative and simple method to prepare isoporous membranes with nanometre-sized pores and the creation of an integral asymmetric membrane of a block copolymer with a highly ordered thin layer on top of a non-ordered sponge-like layer is reported.
Journal ArticleDOI
Amphiphilic Janus Micelles with Polystyrene and Poly(methacrylic acid) Hemispheres
Rainer Erhardt,Mingfu Zhang,Alexander Böker,Heiko Zettl,Clarissa Abetz,Peter Frederik,Georg Krausch,Volker Abetz,Axel H. E. Müller +8 more
TL;DR: Results of fluorescence correlation spectroscopy and field flow fractionation indicate that above a critical aggregation concentration of about 0.03 g/L spherical supermicelles are formed from about 30 PS-PMAA micelles in aqueous solution in the presence of NaCl.
Journal Article
Phase behaviour and morphologies of block copolymers
Volker Abetz,Peter F. W. Simon +1 more
TL;DR: In this paper, an overview of the research on the self-assembly of amorphous block copolymers at different levels of hierarchy is presented, including the influence of composition and topology on the morphologies of block copolerant polymers with linear, cyclic and branched topologies.
Journal ArticleDOI
Multi-walled carbon nanotubes (MWCNTs) mixed polyacrylonitrile (PAN) ultrafiltration membranes
Shahid Majeed,Daniel Fierro,Kristian Buhr,Jan Wind,Bing Du,Adriana Boschetti-de-Fierro,Volker Abetz +6 more
TL;DR: In this article, three different concentrations of hydroxyl functionalized multi-walled carbon nanotubes (MWCNTs) were used in PAN, i.e., 0.5, 1 and 2.
Journal ArticleDOI
Structural Characterization of Graphene Oxide: Surface Functional Groups and Fractionated Oxidative Debris
Elvin Aliyev,Volkan Filiz,Muntazim Munir Khan,Young Joo Lee,Clarissa Abetz,Volker Abetz,Volker Abetz +6 more
TL;DR: A new structural model for GO layers is proposed, which covers all spectroscopic data and explains the presence of the other oxygen functionalities besides carboxyl, phenolic –OH and epoxy groups.
