Origami is an ancient Japanese art of paper folding, which enables fabrication of numerous 3D complex architectures by folding a 2D sheet of paper along prescribed crease-lines. The origami technique has been gaining a lot of attention in the scientific community due to its ability to fabricate 3D architectures of engineering interest. However, majority of the effort has been limited to only papers and few polymeric materials. Towards acknowledging and utilizing the potential of the origami technique, we have recently successfully pioneered the fabrication of carbon and metal carbide origami structures (see the figure below). Here, we aim to expand the materials library of the origami-inspired manufacturing to functional metal oxides. Furthermore, towards enhancing the structural properties of the origami structures, we plan to use electrospinning to generate a nanofibril mat, which can further be folded into the 3D origami shapes.
The specific tasks within the project will be: (i) electrospinning of a polymer precursor; (ii) fabrication of 3D complex shapes of metal oxides through origami techniques and high temperature processes; (iii) characterization of the metal oxide using different analytical techniques such as SEM, Raman, XRD and TEM; and (iv) characterization of the structural properties of the origami structures such as mechanical strength and stiffness.
The candidate will be using the facilities existent the Institute of Microstructure Technology (IMT), i.e., microfabrication facilities and micro-characterization equipment. Furthermore, the candidate will be given the opportunity to co-author in a conference/journal paper.
