Abstract Polystyrene nanofibres reinforced with cellulose nanocrystals have been produced by electrospinning. Two different orientations of the were produced, namely aligned and random, these nanofibrous interleaves investigated both as-spun after thermal treatment. Aligned exhibited a 2500% increase in their Young’s modulus compared to randomly orientated materials, while ultimate tensile stre...
The centrifugal spinning method is a recently invented technique to extrude polymer melts/solutions into ultra-fine nanofibres. Here, we present superior integrated string-based mathematical model, quantify the nanofibre fabrication performance in process. Our model enables us analyse critical flow parameters covering an extensive range, by incorporating angular momentum equations, Giesekus vis...
Over the years, scientists have been continually striving to develop innovative solutions design and fabricate medicines with improved therapeutic potential. Conventional dosage forms, such as tablets, capsules, injections, are limited when exploited for advanced therapeutics, drug targeting. To cater these limitations, nanofibres emerged novel nanomaterials provide enhanced bioavailability, ta...
The actuation of a single hydrogel nanofibre is measured for the first time by AFM. The actuation stress generated was comparable to that produced by skeletal muscle and the actuation rate was significantly increased by the nanoscale dimensions of the fibre.
A simple supramolecular hydrogel based on 1,3:2,4-di(4-acylhydrazide)benzylidene sorbitol (DBS-CONHNH2), is able to extract acid-functionalised anti-inflammatory drugs via directed interactions with the self-assembled gel nanofibres. Two-component hydrogel-drug hybrid materials can be easily formed by mixing and exhibit pH-controlled drug release.
A novel high flux bright light-driven high temperature spinning disc processor operating at ∼720 °C can effectively synthesise carbon nanofibres from fructose, a natural feedstock, in polyethylene glycol-200, within minutes and with multiple reactor passes being a pivotal operating parameter in controlling the growth of the fibres.
