“…So far, polystyrene [83], poly(methyl methacrylate) [84], poly(ethylene terephthalate) [85], polyvinylpyrrolidone [86], polylactic acid [87,88], polyamide 6 [15], polyvinyl acetate [89,90], poly(ethylene oxide) [3,91], polycaprolactone [92,93], polyvinylidene fluoride [4], poly(3-hydroxybutyrate-co-3-hydroxyvalerate) [94] were centrifugally spun however studies reported so far had limited number of parameter with few data points and there is no comprehensive parameter study with detailed experimental design that shows effects of all solution and process parameters on fiber morphology. As reported in a recent review on centrifugally spun nanofibers [95], there were not a systematic parameter study that includes all solution and process parameters of centrifugal spinning including concentration, rotational speed, feeding rate, collector distance and nozzle diameter.…”

Centrifugal spinning is a fast and safe nanofiber production technique and polyacrylonitrile (PAN) nanofibers have been widely studied for many applications including energy storage, filtration, sensors, and biomedical applications. Nanofiber morphology, specific surface area, porosity and average fiber diameter are important to determine the performance of nanofibers in these fields. In centrifugal spinning, nanofiber morphology and average fiber diameter are influenced by solution properties and process parameters including rotational speed, feeding rate, collector distance, and nozzle diameter. In this study, the effect of solution concentration, rotational speed, feeding rate, collector distance and nozzle diameter on average fiber diameter and fiber morphology were studied and statistical analysis was performed to determine the main factors. Optimum solution and process parameters were determined as well. Increased average fiber diameter was seen with increasing polymer concentration and nanofibers produced at 4000 rpm with the feeding rate of 60 ml/h had the lowest average fiber diameter for all studied nozzle sizes (0.3 mm, 0.5 mm and 0.8 mm). 8 wt. % PAN solution was centrifugally spun with the rotational speed of 4000 rpm, feeding rate of 60 ml/h, collector distance of 20 cm and nozzle diameter of 0.3 mm and bead free nanofibers with the average fiber diameter of 680 ± 87 nm was observed.

“…Critical concentration refers to the concentration at which the fiber begins to exhibit homogeneous, continuous, bead-free fiber. By raising polymer concentration, the existence of beads along the fibers may be minimized [59]. The optimal concentration is the one that gives rise to the development of bead-free fiber with the most homogeneous morphology.…”

Over the last decade, researchers have investigated the potential of nano and microfiber scaffolds to promote wound healing, tissue regeneration, and skin protection. The centrifugal spinning technique is favored over others due to its relatively straightforward mechanism for producing large quantities of fiber. Many polymeric materials have yet to be investigated in search of those with multifunctional properties that would make them attractive in tissue applications. This literature presents the fundamental process of fiber generation, and the effects of fabrication parameters (machine, solution) on the morphologies such as fiber diameter, distribution, alignment, porous features, and mechanical properties. Additionally, a brief discussion is presented on the underlying physics of beaded morphology and continuous fiber formation. Consequently, the study provides an overview of the current advancements in centrifugally spun polymeric fiber-based materials and their morphological features, performance, and characteristics for tissue engineering applications.

Virgin coconut oil (VCO) has become a multifunctional material for biomedical applications due to its remarkable health benefits. The use of VCO for biomedical applications has seen tremendous growth over recent years, triggering researchers to develop various approaches for VCO utilization. Nanofibers‐based structure offers promising properties to encapsulate VCO, enhancing its performance and broadening its application in the medical field. Studies of VCO‐loaded polymeric nanofibers for biomedical applications are currently gradually rising. Recently, in nanofibers technology, centrifugal jet spinning (CJS) offers cost‐efficient and higher production rates to yield nanofibers compared to the other methods. This review summarizes recent advances of VCO for biomedical applications. Comprehensive suggestions for encapsulating VCO into nanofibers using the CJS technique are also provided. Highlights of future challenges in utilizing the CJS technique to produce VCO‐loaded nanofibers for biomedical applications are also elaborated.
