Droplet assisted growth and shaping of alumina and mixed alumina-silicone 1-dimensional nanostructures


Saddiqi, Naeem-ul-Hasan; Seeger, Stefan (2020). Droplet assisted growth and shaping of alumina and mixed alumina-silicone 1-dimensional nanostructures. Journal of Colloid and Interface Science, 560:77-84.

Abstract

Since the discovery of silicone nanofilaments a decade ago, room temperature droplet assisted growth and shaping using silanes has been used to synthesize various silicone-based nanostructures. In the present work, we report an extension of this synthesis technique to synthesize nanostructures of new materials. We have successfully synthesized one-dimensional assemblies of beads or necklaces based on alumina (Al) and mixed alumina-silicone (Al Si) nanostructures exhibiting a similar structure as silicone nanofilaments. The characterization of the synthesized nanostructures was performed using different tools, including scanning and transmission electron microscopy, energy dispersive x-ray spectroscopy, and infrared and NMR spectroscopy. Selected area electron diffraction revealed that the nanostructures are amorphous in nature, and the growth behavior and thermal stability of nanostructures are also discussed
