poly(vinylidene fluoride) (pvdf) fibers with two molecular weights were prepared via electrospinning process. in this process, the concentration of spinning depended drastically on the gelation process. also, it was experimentally smaller than obtained concentration in the solution entanglement number approach (sena). proof of this incompatibility was explained by the properties of pvdf and its...

Abstract Silk fibre mechanical properties are attributed to the development of a multi-scale hierarchical structure during spinning. By careful ex vivo processing B. mori silkworm silk solution we arrest spinning process, freezing-in mesoscale structures corresponding three distinctive stages; gelation, fibrilization and consolidation phase identified in this work, process highlighted by emerge...
