| Abstract Scope |
Pressure spinning (pressurised gyration), invented about a decade ago is a simple scalable process of spinning fibrous morphologies from functional soft materials to allow high yield low energy manufacturing for healthcare, e.g. pharmaceutics, antimicrobial filtration, tissue engineering. Here simultaneous rotation under pressure is facilitated in a vessel containing numerous surface orifices but other process control parameters such as flow rate of solutions and alloying can also be added to generate core-sheath and tubular scaffolds. Versions of nozzle pressurised gyration have allowed the use of sustainable, green and environmentally friendly manifestations of the process so that value-added manufacturing of a new generation of oriented biomaterials is possible. Recently vessel design has been investigated to optimize manufacturing with focus on automated industrial adaption of the process. Examples of these developments using both traditional and newer biomaterials will be qualitatively and quantitatively analysed, and comparison with other forming technologies will be discussed. |
