Dr Sulley Li, A/Prof Minoo Naebe, Dr Weiwei Lei and team have a cover paper in Advanced Science. The paper, titled ‘Porous Fibers: Controlled Design of a Robust Hierarchically Porous and Hollow Carbon Fiber Textile for High‐Performance Freestanding Electrodes’, proposes an innovative dynamic template calcination strategy to construct a hierarchical macro–meso–microporous and hollow carbon fibre textile system without diminishing mechanical robustness. Such unique characteristics offer high surface area and minimized diffusive resistance to mass transport, resulting in a flexible and efficient freestanding electrode.
A/Prof Luke Henderson and team – Daniel Eyckens, Chantelle Arnold, James Randall,Filip Stojcevski, Andreas Hendlmeier and Melissa Stanfield, with collaborators from Deakin SEBE, CNRS and CSIRO have a new paper in ACS Appl. Mater. Interfaces on coloured and colour changing carbon fibre.
Their results show carbon fibres incorporating structural color, similar to that observed on the surface of soap bubbles and various insects and birds. When dry, the treated fibres exhibit a striking blue color, but when exposed to a volatile solvent, a cascade of colors across the visible light region is observed. The treated fibres can also be reversibly formed into complex shapes and bear significant loads even without being encased in a supporting polymer. The tensile strength of treated fibres shows a statistically significant increase (+12%), and evaluation of the fibre-to-matrix adhesion of these polymers to an epoxy resin shows more than 300% improvement over control fibres. This approach creates a new platform for the multifaceted advance of smart composites. Fiber with Butterfly Wings: Creating Colored Carbon Fibers with Increased Strength, Adhesion, and Reversible Malleability
Associate Professor Minoo Naebe and colleagues have published an invited review paper in the prestigious journal Progress in Materials Science, titled “PAN Precursor Fabrication, Applications and Thermal Stabilization Process in Carbon Fiber Production: Experimental and Mathematical Modelling”.
This paper is the first comprehensive review that provides a general understanding of the links between PAN fibre structure, properties, and its stabilization process along with the use of mathematical modelling as a powerful tool in prediction and optimisation of the processes involved. Read more
