Abstract
Abstract
This paper reviews different methodologies for the fabrication of various ceramic one-dimensional (1D) nanostructures (nanotubes/fibres/wires/belts, etc.) produced by using preceramic polymers. Diverse processing approaches together with a wide range of precursor types enable the fabrication of 1D nanostructures with varied morphology, composition, purity as well as yield. The strategies used are based on three different methods; starting with the utilisation of decomposition gases which are released upon pyrolysing the preceramic polymer precursors at high temperatures, with the absence or presence of a catalytic metal source. The second is the template modulated synthesis routes (i.e. infiltration of the polymeric precursor melt or solution inside a template porosity, polymer to ceramic conversion followed by the removal of the template), and the last strategy discussed is electrospinning.
Some parts of the present paper were derived from the PhD thesis of C. Vakifahmetoglu which was recently completed under the supervision of Professor Ing. Paolo Colombo. The author wishes to express deepest gratitude to him for his endless support, feedback and encouragements.
This article is dedicated to the memory of Onur Yaser Can, a lovely dear friend who recently passed away but will always be in the heart.
