“…Process conditions such as applied voltage, flow rate and distance from needle to collector affect the morphology of fibers. Ding et al reported that average diameter of poly(vinyl alcohol) (PVA) fibers are slightly decreased with increasing the voltage, by study average diameter as a function of voltage at conditions (concentration = 11% and needle-collector distance = 8 cm) [61]. Rodoplu and Mutlu reported that when other parameters are kept constant and voltage increased, PVA nanofiber diameter decreases.…”

By electrospinning technique, nanofiber can be produced due to applied high potential voltage on polymer solution, leading to the formation of a jet from polymer solution that is collected on a collector in a nanofiber shape. In the last decade of the twentieth century with appearance of nanotechnology, work and publications on optimization of electrospinning and its applications increased exponentially. Morphology of produced nanofiber depends on three groups of parameters: 1- process conditions (applied voltage, flow rate and needle-to-collector distance) 2- solution conditions (concentration, molecular weight and degree of hydrolysis) 3- ambient conditions (temperature and humidity). Brief history from observation of change of the spherical shape of liquid droplet by the effect of the electrical force to conical shape, passing by Formhals patents to use portable electrospinning techniques will be mentioned. Because of various advantages of nanofiber such as high pore density and enormous surface area per volume ratio, there are vital applications based on nanofiber, for example water treatment, air filtration, sensors/biosensors, energy storage, tissue engineering, wound dressing and drug delivery system.

“…However, different ways for controlling the process temperature were reported. Temperature-controlled electrospinning can thus refer to heating only the syringe/polymer solution dispensing system [8,12], the collector [14] or the whole enclosure of the device [7,11,13]. This last approach is particularly relevant since it avoids the formation of temperature gradients which can interfere with the fiber formation process.…”

The introduction of highly volatile fragrances within polymeric nano-scaled fibers is a promising route for efficient and simple encapsulation of temperature-sensitive materials. This work describes the investigation of selected parameters influencing the electrospinning of emulsions of poly(vinyl alcohol) (PVA) and (R)-(?) limonene or hexadecane. Thereby the influence of environmental parameters such as temperature and relative humidity on the fiber structure and encapsulation efficiency (EE) of the fragrance is demonstrated. For that purpose, the electrospinning process was carried out in a climatic cabin in which temperature and relative humidity were controlled. Studied temperatures ranged from 8 to 24°C and relative humidity varied between 55 and 85 %. The influence of temperature was dependent on the PVA concentration in the emulsion. The relative humidity influenced both the obtained fiber morphology and fragrance EE to a higher extent than the temperature due to the hydrophilic nature of the PVA. This study is of importance when considering the use of emulsion electrospinning for encapsulation purposes.

The electrospun fibers can have applications in diverse fields, such as tissue scaffolds, optical electronics, nanocatalysis, and sound absorption. Nanoscale fibers with a higher surface area can provide superior mechanical, physical, and thermal properties. Therefore, investigation of the factors affecting the electrospinning process, for various materials, is required. In this study, the design of experiments issued for optimization of electrospinning of polyvinyl alcohol (PVA). Analysis of variance (ANOVA) and the Taguchi orthogonal array L27OA are employed to analyze the influence of process control parameters. The variables studied are the applied voltages, solution concentrations, rotational speeds, collecting distances, and flow rates.A mathematical model of the polymer fiber diameter as a function of significant process parameters has been built using response surface methodology (RSM). The concentration percentage and the flow rate were determined to be the most significant process variables at 99% and 90% confidence levels, respectively. The predictive model provides 84.34% average model accuracy, which is considered acceptable as this study deals only with 27 of 243 trials needed for a full study based on principles of design of experiments. An additional ANOVA test and corresponding mathematical model have been developed to obtain the interaction effects for processing parameters.
