[seminar] Utorak, 5.XI.2013. Reitz, Mesostructured Metal Oxide Thin Films with Cubic Pore Symmetry and Ferroic Properties

[Damir Pajic]

Poštovane kolegice i kolege,

U utorak, 5.XI.2013. na Fizičkom odsjeku PMF-a u predavaonici F201 (II. 
kat) s početkom u 14h predavanje naslovljeno "Mesostructured Metal Oxide 
Thin Films with Cubic Pore Symmetry and Ferroic Properties" održat će 
Christian Reitz (Institute of Nanotechnology, Karlsruhe Institute of 
Technology, Germany).

Sažetak:

Metal oxide thin films with both a mesoporous morphology and a highly 
crystalline wall structure have received significant attention over the 
past several years. This is due, in part, to the fact that many such 
materials have been shown to be able to outperform their bulk 
counterparts, which is particularly evident in the forefront fields of 
energy storage, catalysis, and information technology.

Advances in polymer templating of inorganic materials have enabled the 
preparation of a variety of mesoporous metal oxides with different pore 
structures, including cubic and 2D-hexagonal. Their formation relies on 
the solution-phase coassembly of inorganic building blocks with an 
amphiphilic polymer structure-directing agent using an 
evaporation-induced self-assembly (EISA) process to achieve long-range 
periodicities reminiscent of lyotropic liquid crystal phases. However, 
despite the progress made, many polymer-templated materials described in 
the literature exhibit an ill-defined porosity after crystallization. 
Part of the reason for this is the difficulty of controlling the 
amorphous-to-crystalline conversion at elevated temperatures while 
retaining nanoscale structure.

In this talk, I specifically focus on ferroic metal oxide thin films - 
including LSMO and PZT - materials that can be readily produced with a 
cubic network of large pores by utilizing tailor-made 
poly(ethylene-co-butylene)-block-poly(ethylene oxide) and 
polyisobutylene-block-poly(ethylene oxide) diblock copolymers as 
structure-directing agents. Such materials might offer the possibility 
to develop novel “nano-enabled” device design.
