“…10,14 However, no nanofiber has been reported from a single polymeric material having no polar group, especially of common polyolefins (PP and PE). 12 Recently, our research team have been introduced polyvinyl butyral as a polar assistance and manufacture PP 24 and lowdensity polyethylene (LDPE) 25 nanofibers with a few hundred nanometers in diameter.…”

The ultimate functionality and applicability of polymeric nanofibers are mainly to subject on its diameter. This study explores the influence of melt flow rates (MFRs) of low-density polyethylene (LDPE) on the diameter of laser melt electrospun nanofibers. Ethylene-vinyl alcohol (EVOH) copolymer was added to the nonpolar LDPE as a spinning aid. After electrospinning, the EVOH was removed from LDPE/EVOH blend fiber by treating with isopropanol/water solution and LDPE nanofiber was obtained with a diameter of only 190 ± 85 nm for the highest MFR. A linear diameter reduction was observed for pure LDPE and EVOH removed LDPE fiber with the increase of MFR. However, a slight diameter increment was reported for the LDPE/EVOH blend fiber with higher MFR due to the improved melt viscosity of the component. A massive diameter decrement was found after EVOH removal from the blended fiber, resulting in the renovation of microfiber to a stable nanoscale dimension.

“…Our recent works have observed a similar effect of matrix materials (polyvinyl butyral and EVOH) on the electrospun fiber diameter and its underlying reasons, weight ratios as well as polymer melt flow rate have been discussed in details. [17][18][19] We observed the two-step fiber diameter reduction; first, due to the addition of matrix during electrospinning, second, for its removal after electrospinning. Normally, for EVOH removal from PP/EVOH blend fiber resulted in the multiple splitting of PP fiber, ensuring a massive drop in fiber diameter.…”

“…However, the electrospun polyolefin fiber on a nanoscale level is really difficult due to its high melt viscosity and nonpolarity. The recent techniques such as the addition of viscosity reducing additives, 13 the inclusion of conductive salts, 14,15 and preparation of in-situ fibrillar composites using polar matrix [16][17][18][19] have made it more successful to manufacture electrospun polyolefin fiber on a nanoscale level. The immiscible blends having dispersed phases in fibrillar morphology are called in situ fibrillar composites, are more promising to prepare polyolefin microor nanofibers followed by selective removal of the matrix.…”

A fibrous membrane being prepared from nanofiber is of great demand for super‐efficient filtration of industrial wastewater. This study reported a highly efficient noanofibrous membrane made of superfine polypropylene (PP) nanofiber with an average diameter of only 228 nm and that had also demonstrated a direct influence of fiber diameter on its properties and performance for textile wastewater purification. The PP nanofibers were prepared with a varying content of PP/ethylene‐co‐vinyl alcohol (EVOH) blends from which the EVOH matrix was removed after electrospinning. Subsequently, the PP nanofibrous membranes were manufactured using the prepared PP nanofibers via a simple wet‐laid process. The fiber diameter turned out to be an important factor in the surface properties and pore characteristics of the PP nanofibrous membrane. The finer PP nanofiber constructed a compact fibrous mesh structure of the membrane leading to an optimum porosity, a high hydrophobicity, and a smaller mean pore size with a narrower distribution. The filtration performance of the nanofibrous membrane for dyeing wastewater has also evidenced the potentiality of the finer PP nanofiber. Moreover, in comparison with the commercial PP fibrous membrane, the developed PP membrane was found to be more promising.

“…The stretching frequency of C–H appeared at 2750–3000 cm −1 , while bending at 1300–1500 cm −1 . Typical bonds of PVB were presented at 1132 cm −1 and 999 cm −1 , respectively corresponding to the butyral ring (C–O–C) and C–O stretching [ 29 , 37 ]. FTIR spectra analysis confirms urea presence in all PVB patches.…”

Skin diseases such as atopic dermatitis (AD) are widespread and affect people all over the world. Current treatments for dry and itchy skin are mostly focused on pharmaceutical solutions, while supportive therapies such as ointments bring immediate relief. Electrospun membranes are commonly used as a drug delivery system, as they have a high surface to volume area, resulting in high loading capacity. Within this study we present the manufacturing strategies of skin patches using polymer membranes with active substances for treating various skin problems. Here, we manufactured the skin patches using electrospun poly(vinyl butyral-co-vinyl alcohol-co-vinyl acetate) (PVB) fibers blended and electrosprayed with urea. The highest cumulative release of urea was obtained from the PVB patches manufactured via blend electrospinning with 5% of the urea incorporated in the fiber. The maximum concentration of released urea was acquired after 30 min, which was followed up by 6 h of constant release level. The simultaneous electrospinning and electrospraying limited the urea deposition and resulted in the lowest urea incorporation followed by the low release level. The urea-based patches, manufactured via blend electrospinning, exhibited a great potential as overnight treatment for various skin problems and their development can bring new trends to the textile-based therapies for AD.
