Preparation of high-value pitch-based carbon fibres (CFs) from mesophase pitch precursor is of great importance towards low-cost CFs. Herein, we developed a method to reduce the cost of CFs precursor through incorporating high loading of coal tar pitch (CTP) into polyacrylonitrile (PAN) polymer solution. The CTP with a loading of 25% and 50% was bl...

Electrically conductive scaffolds are of significant interest in tissue regeneration. However, the chemistry of the existing scaffolds usually lacks the bioactive features for effective interaction with cells. In this study, poly(ε-caprolactone) was electrospun into aligned nanofibers with 0.58 μm average diameter. Electrospinning was followed by p...

Low interface strength is a common challenge in taking full advantage of excellent physical performances of carbon fibre (CF) reinforced polymer composites. Herein, for the first time, we have used amino-functionalized nanoclay as a linkage between CF surface and epoxy matrix, which by a cation exchange process was grafted on the CF surface. Amino-...

Titanium oxide nanotube (TiO2 nanotube) arrays were produced by anodizing titanium foils in two different electrolytes. The first electrolyte consisted of ethylene glycol containing 0.5 wt% NH4F and 4 vol% of distilled water to produce pure TiO2 nanotube arrays and the second consisted of HF aqueous solution (0.5 wt%) containing 0.5% polyvinylalcoh...

Micro/nano electrodes employing nanotubes has attracted paramount attention in recent years due to their inherent superior mechanical and structural properties. Electrical interfaces with different geometries and sizes have been developed as electrodes for measuring action potentials and investigating neural information processing in neural network...

The electrical conductivity of biodegradable polymeric scaffolds has shown promising results in tissue engineering, particularly for electrically excitable tissues such as muscles and nerves. Herein, we demonstrate a novel processing approach to produce electroactive nanofibres. Electrically conducting, robust nanofibres comprising both a biodegrad...
Article
Development of new chemical approaches for preparation of engineered carbon-based fillers is critical for high-performance applications. Herein, an efficient method for covalent functionalization of polyacrylonitrile-based carbon fibre through azo radical addition under mild condition is demonstrated. In this way, isobutyronitrile radicals in situ...
