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...
