ACMIN Seminar: „Polymer Derived Ceramics – modern materials for energy industry, aviation, catalysis, biomaterials and…”
It is our pleasure to invite you to attend the ACMiN Seminar which will be held on Thursday, October 13 at 2.00 p.m. in the ACMiN auditorium no.: 1.02A, on the second floor, bldg. D-16 (Kawiory Street 30).
The lecture entitled: „Polymer Derived Ceramics – modern materials for energy industry, aviation, catalysis, biomaterials and …” will be given by Dr Maciej Bik (AGH, Faculty of Materials Science and Ceramics, Cracow, Poland)
Polymer Derived Ceramics (PDCs) drew scientists’ attention already 50 years ago due to an outstanding chance to tailor their properties during all steps of material’s formation process. These are typically Si-based materials of prominent characteristics including thermomechanical stability, oxidation and chemical resistance, high mechanical strength, as well as electrical conductivity and piezorestivity. The key factor leading to such properties is possibility to control:
A) the chemical composition and/or structure via application of single-source precursors approach, hydrosililation, sol-gel method,
B) geometry and/or shape of materials via application of plastic forming, casting, 3D printing or coating deposition (dip-, spin-, spray coating) of polymeric precursors,
C) final microstructure and properties by means of oven pyrolysis, plasma or UV treatment, vapor deposition, SPS.
Therefore, PDCs have already found abundant applications in all kind of forms (bulk – anode material for Li-ion batteries, coatings – oxidation protection for metallic substrates, porous – catalysis, fibers – Polymer Matrix Composites).
Main aim of this talk is to provide an overview of studies on SiOC glasses as one of the most intriguing representative of PDCs – protective coatings for Solid Oxide Fuel Cells interconnects and TiAl-based turbine blades, bulk and coatings for tissue engineering and 3D structures with predesigned architecture for catalysis.
