“…Figure 3 presents the results of the mean contact angle values obtained for each membrane. The values of the contact angle measured for the control membranes, 78.4 • for the PES membrane and 92.3 • for the PVDF membrane, are in agreement with the ones found for hollow fiber membranes in the literature [22][23][24][25].…”

In this study, mixed matrix hollow fiber polymeric membranes were prepared using polyethersulfone (PES) and polyvinylidene fluoride (PVDF) as polymers in their composition. N-methyl-2-pyrrolidone (NMP) was used as a solvent and demineralized water with an electrical conductivity below 3 μS·cm−1 was used as a non-solvent. A new approach to producing enhanced polymeric hollow fiber membranes based on the preparation of a simple blend PVDF/PES solution, and on the conformation of the composite membranes through the extrusion technique followed by the phase inversion process in a non-solvent bath, was applied. The investigation focused on the preparation of polymeric membranes with different polymer ratios and further assessment of the effects of these proportions on the membrane performance and in specific physical properties. The amount of PVDF ranged from 10 to 90% with 10% steps. The presence of PVDF, although it increased the membranes’ plasticity, had a negative effect on the overall mechanical properties of the composite membranes. Scanning electron microscopy (SEM) results showed good dispersion of both polymers in the polymeric matrix. Furthermore, the membrane permeability showed a slight negative correlation with contact angle, suggesting that membrane hydrophilicity played an important role in membrane permeability. Finally, it was found that membranes with low ratios of PVDF/PES may have potential for water treatment applications, due to the combined advantageous properties of PES and PVDF.

“…First of all, the dominant peaks were associated with strong C, O, and N signals in synthetic fibers, as well as with complex Cu and Se X-ray lines (Figure 11). Other investigators [29][30][31] also reported peaks corresponding to C, O, and N obtained from the analysis of untreated PAN fibers, PA6 fibers [32], PA66 [33], and PES fibers [34]. The Cu and Se peaks emanating from the Cu x Se coatings confirmed the formation of a welldefined thin coating layer.…”

Textile production has been steadily increasing for a few decades and, as a result, the amount of industrial textile waste is also increasing. This waste can be reused as raw material to produce new functional composites. Such materials can be used for special purposes with varying combinations of physical and chemical properties by using polymers modified with thin semiconductive or electrically conductive layers of binary inorganic compounds. In this paper, a study of the possibilities of altering the properties of synthetic fiber conductivity by modification with copper selenide is presented. A two-step adsorption/diffusion method was used for the copper selenide layer forming on the surface of the fibers. The treatment process was repeated cyclically. To evaluate the morphological properties of CuxSe treated fibers, scanning electron microscopy (SEM) and energy dispersion X-ray (EDX) were performed. The study showed that the chosen modification method is more suitable for PA and PAN fibers. Dense layers of copper selenides were successfully formed on their surface, which significantly reduced their electrical resistance.

“…However, the formulation development and manufacturing phases of film dosage forms face numerous challenges that must be addressed to optimize the overall formulation, even during large-scale production [22]. As new technologies are rapidly introduced to prepare thin films, the future of film technology in the field of pharmaceuticals appears very promising [23].…”

This research interrogates the effect of loading phenolic resin (\({C}_{8}{H}_{6}{O}_{2}\)) and graphene oxide (GO) solutions into a polyethersulphone (PES) matrix to improve the physio-mechanical properties of PES. A new class of thin-film was successfully synthesized by incorporation of phenolic resin (\({C}_{8}{H}_{6}{O}_{2}\)) and graphene oxide (GO) solutions into a 2 wt% polyethersulphone (PES) matrix and its application in pharma packaging was investigated. To alter the mechanical properties of the thin films, a mixture of phenolic resin and graphene oxide was dispersed into a prepared polyethersulphone solution at varying concentrations using a solution mixing technique. the XRD spectra for PES/GO/PR thin films to confirm the presence of GO. The sharp peak was observed at 2θ = 19.79˚. The tensile testing of the polyethersulphone composite thin films revealed an increase in the tensile strength, which rose from 3.74 to 33.91 MPa, and Young's modulus was also improved from 9.97 to 20.85 MPa. Additionally, there was a significant improvement in the percentage elongation, which rose from 1.02 to 1.66% for PC-4, indicating a strong agreement between the filler used and the composition method.
