Different Levels

The preparation and morphological characterization of a so-called composite membrane based on a 3-miktoarm star terpolymer on a support layer is reported. It is demonstrated that different levels of order and different morphological orientations can be obtained by directly casting the star terpolymer solution on the support, depending on the prior treatment of the support layer and the casting conditions.

In recent years, block copolymer lithography has emerged as a viable alternative technology for advanced lithography. In chemical-epitaxy-directed self-assembly, the interfacial energy between the substrate and each block copolymer domain plays a key role on the final ordering. Here, we focus on the experimental characterization of the chemical interactions that occur at the interface built between different chemical guiding patterns and the domains of the block copolymers. We have chosen hard X-ray high kinetic energy photoelectron spectroscopy as an exploration technique because it provides information on the electronic structure of buried interfaces. The outcome of the characterization sheds light onto key aspects of directed self-assembly: grafted brush layer, chemical pattern creation and brush/block co-polymer interface.
