Marina Turalina, B.sc. is employed at the Faculty of Textile Technology since 1st of September 2009 as the researcher on the T-Pot project. From the very first day she started her research work at the premises of EMPA, where she will stay for 6 months.
The measure of mobilisation of human resources is promoting knowledge exchange and strengthening of the relationship between particular textile departments and further contributing to the broadening of ERA. Only highly-educated and trained researchers can apply modern technologies that stimulate productivity, competitiveness and can create the knowledge-based society, mentioned in the Lisbon Declaration of the European Union.
EMPA (Swiss Federal laboratories for materials Testing and Research) is hosting institution of TTF-s researcher under the task T.2.4 Researchers secondments up to 6 months
EMPA was founded in 1880 in the cellars of Zurich Polytechnic University, the forerunner of ETH Zurich. Over more than 100 years development, today EMPA become an interdisciplinary research and services institution for material an interdisciplinary research and services institution for material sciences and technology development. Their research activities cover the following domain: Advanced Materials and Surfaces, Civil and Mechanical Engineering, Materials and Systems for the Protection & Wellbeing of the Body – Information, Reliability & Simulation Technology, Mobility, Energy and Environment.

The department Materials and Systems for the Protection & Wellbeing of the Body covers the following activities: Protection and Physiology, Advanced Fibers, Materials-Biology Interactions and Biomaterials. The laboratory of ADVANCED FIBERS, combines know-how and competences from various disciplines such as Chemistry, Physics, Biomaterials, Surface and Materials Science as well as Plasma- and Nanotechnology. This combination of expertise is an ideal prerequisite for the development of advanced fibers with novel properties.
ADVANCED FIBERS research activities:
1. Polymers & Processing
They develop advanced synthetic fibers using new combinations of materials to achieve improved or novel properties. Therefore, they make use of their pilot melt spinning plant or other spinning techniques. The resulting multi-component or (nano-) composite fibers are produced in quantities that allow industrial testing and prototyping. The fibers’ geometrical shape can be modified during spinning; alternatively, microstructures can be imprinted onto the fiber surface in post-processing.
2. Plasma & Coating
Low pressure plasma technology is used to modify fiber and textile surfaces. Processes like activation, cleaning, cross-linking, plasma-polymerization, plasma-metallization and combinations thereof can be far better controlled in low pressure plasmas. As a clear-cut advantage of plasma coatings, the original textile properties (i.e., flexibility, processability, haptics) are not altered. With their plasma reactors and pilot plants they can address a wide range of issues from research all the way to industrial applications.
3. Additives & Chemistry
They focus on the synthesis of new additives that can be used in polymer processing or surface coatings. Therefore, they maintain a synthesis laboratory and work with comprehensive chemical analytics that are also available to their external clients.
4. Surfaces & Interfaces
This research activity is a collaborative effort between different institutions within the ETH domain. With very sensitive instruments we study the molecular order, dynamics and interactions near surfaces. Their main partners are at the ETH Zürich and at the PSI Villingen.

The group of Additives & Chemisty is working on the following topics:
Synthesis of novel chemical compounds for additives, polymers or coatings, which bestow new properties upon synthetic fibers or textiles. Properties of particular interest include flame retardance, UV protection, photocatalysis, crystallization during spinning or the release of substances. Operation and development of high-standard chemical and instrumental analytics as used in their research activities and for external bodies from industry or public authorities. During the research secondment in EMPA - St. Gallen, in group of Additives & Chemisty, supervisor of Marinas research work is Dr. Sabyasachi Gann.
