NANOMATERIALS, TEXTILES, AND ADVANCED COMPOSITES RESEARCH GROUP

"Nanomaterials, Textiles, and Advanced Composites Research Group" is an association of research groups within the Department of Aeronautical Engineering at Istanbul Technical University and Royal College of Art, School of Design, Textiles, which is led by Assoc. Prof. Hülya Cebeci and Assoc. Prof. Elif Özden Yenigün. The major themes at the moment are those of Assoc. Prof. Hülya Cebeci and Assoc. Prof. Elif Özden Yenigün, which embrace polymeric systems, carbon nanomaterials including carbon nanotubes, graphene, as well as boron nitride nanotubes, nanofibers, their assembly into composite materials and the resultant properties. The research focus is on carbon and boron based functional nanomaterials starting from the synthesis to final applications including nano-engineered structural materials, sensors and energy storage through experimental approaches while benefiting from computational techniques. 

Other areas that interest us stem from goal of developing functional nanomaterials and using them in composite applications including, fuel cell applications, sensing and 3D printing and filtration. The aim of this multidisciplinary group’s research is to transfer the outstanding mechanical, thermal, and electrical properties of nanomaterials, as can be in the form of tubes, films, mats and yarns into innovative, functional materials. Recent research projects are classified under three main focus:

  • Nano-Engineered Composite Structures & Polymer Nanocomposites

  • Additive Manufacturing

  • 3D Woven Composites

  • Wearable Electronics
