“…The porosity of the fibrous materials after production and surface modification was determined based on the following relation: P(%) = (1 − d s /d p ) × 100%, where d s —sample density, d p —polymer density (1.12 g∙cm −3 ). Disc samples were weighed, and sample density was calculated: d s = m/(δ∙A), where m—sample mass (g), δ—sample thickness (cm), A—sample area (cm 2 ) [ 57 ]. The sample thickness was measured using SEM.…”

The use of nanofibrous materials in the field of tissue engineering requires a fast, efficient, scalable production method and excellent wettability of the obtained materials, leading to enhanced cell adhesion. We proposed the production method of superhydrophilic nanofibrous materials in a two-step process. The process is designed to increase the wettability of resulting scaffolds and to enhance the rate of fibroblast cell adhesion. Polyurethane (PU) nanofibrous material was produced in the solution blow spinning process. Then the PU fibers surface was modified by dopamine polymerization in water solution. Two variants of the modification were examined: dopamine polymerization under atmospheric oxygen (V-I) and using sodium periodate as an oxidative agent (V-II). Hydrophobic PU materials after the treatment became highly hydrophilic, regardless of the modification variant. This effect originates from polydopamine (PDA) coating properties and nanoscale surface structures. The modification improved the mechanical properties of the materials. Materials obtained in the V-II process exhibit superior properties over those from the V-I, and require shorter modification time (less than 30 min). Modifications significantly improved fibroblasts adhesion. The cells spread after 2 h on both PDA-modified PU nanofibrous materials, which was not observed for unmodified PU. Proposed technology could be beneficial in applications like scaffolds for tissue engineering.

“…According to Zhang et al, it is viable for a large-scale industrial production of oil sorbents and oil spill clean-up for the protection of the environment [81]. The SBS-spun nanofibrous polystyrene membranes (NPS) could separate oil from water surface in a matter of seconds [82]. A composite membrane of SBS poly (methyl methacrylate) nanofibres wrapped with reduced graphene oxide (PMMA-rGO) was fabricated to adsorb the typical dye called methylene blue (MB) [83].…”

Submicron/nanofibres possess great potential for application in different areas because of their amazingly high surface area-to-weight ratio. The demand for fabrication of such fibres on a huge scale is increasing with the fast improvement of nanotechnology. Traditionally, nanofibre fabrication methods have intrinsic faults, limiting their application in industry. Solution blow spinning (SBS) is a viable option for producing adaptable and conformable submicron/nanofibre mats on a variety of surfaces. The technique can be employed to produce submicron/ nanofibres with only a simple commercial airbrush, a concentrated polymer solution, and a compressed gas source. It depends on the high velocity of decompressed air that allows the rapid stretching and evaporation of the solvent from a polymeric solution jet at the outlet of the concentric nozzles system. Along with recent advancements, the importance and drawbacks of the solution blow spinning system in comparison to other methods, such as electrospinning and melt blowing, are briefly discussed. Furthermore, the mechanisms of co-axial SBS spinning and micro SBS spinning system for submicron/nanofibre fabrication are also described. Drawbacks and research challenges of SBS are also addressed in this paper.

“…After the evaporation of the solvent, the prepared fibers deposit on the collector. The fibrous membranes prepared by SBS have been used in various fields, including tissue engineering, drug carrier, oil adsorption, etc, because of their large pore size and rough fiber surface . SBS can also be used to adsorb oil in situ through spraying the fibers directly onto the oil/water mixture, which is quite highly efficient and easy to operate.…”

In this paper, biodegradable polycaprolactone (PCL) was used as the raw material to prepare micro/nanofibrous polycaprolactone membrane (PCLM) through solution blow spinning (SBS) technology. The effects of spinning conditions (distance, gas pressure, and spinning solution concentration) on PCLM structures were investigated. The obtained membranes were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy, water contact angle, and thermogravimetric analysis instrument. The oil adsorbency and reusability of PCLM were measured. The oil adsorption capacity of PCLM for motor oil, peanut oil, and diesel oil was 15.93, 14.81, and 12.86 g·g−1, respectively. After 10 times of reuse, the adsorption capacity for motor oil, peanut oil, and diesel oil could still remain at about 80% of the first cycle. The kinetic and thermodynamic studies showed that the adsorption conformed to the first‐order kinetic model and Freundlich model. Thermodynamic parameters for oil adsorption ΔGθ, ΔHθ, and ΔSθ indicated the oil adsorption of PCLM was a spontaneous and physisorption process.
