“…Numerous attempts have been made to decrease the surface tension and obtain a fibrous structure with a lower level of defects. 33 Table 1 summarizes the findings on surface tension and conductivity for all of the prepared solutions. The surface tension values of the various PVDF-co-HFP solutions were relatively low, ranging from 36 to 38 mN/ m. The primary factor in this pertains to the character of the solvent, DMF in this case, which attains relatively low surface tension (about 35 mN/m).…”

“…39 The increased hydrophilicity of the electrospun membranes instigated by the surfactants was confirmed by findings in the literature. 33,40 It is worthy to note that hydrophilic surfaces are beneficial in filtration applications as they can enhance the water permeability of nanofibrous membranes. 35 This hydrophilic character of the membranes significantly boosts their associated antifouling properties, 40 too, as proven herein through appropriate testing (see Sections 3.2.3 and 3.2.4).…”

The efficiency of filtration membranes is substantially lowered by bacterial attachments and potential fouling processes, which reduce their durability and lifecycle. The antibacterial and antifouling properties exhibited by the added materials play a substantial role in their application. We tested a material poly(vinylidene fluoride)-co-hexafluoropropylene (PDVFco-HFP) based on an electrospun copolymer, where an agent was incorporated with a small amount of ester of glycerol consecutively with caprylic, capric, and lauric acids. Each of these three materials differing in the esters (1-monoacylglycerol, 1-MAG) used was prepared with three weighted concentrations of 1-MAG (1, 2, and 3 wt %). The presence of 1-MAG with an amphiphilic structure resulted in the hydrophilic character of the prepared materials that contributed to the filtration performance. The tested materials (membranes) were characterized with rheological, optical (scanning electron microscopy, SEM), Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), and other methods to evaluate antibacterial and antifouling activities. The pure water flux was 6 times higher than that of the neat PVDF-co-HFP membrane when the added 1-MAG attained only 1 wt %. It was experimentally shown that the PVDF-co-HFP/1-MAG membrane with high wettability improved antibacterial activity and antifouling ability. This membrane is highly promising for water treatment due to the safety of antibacterial 1-MAG additives.

“…These findings concur with the SEM analysis, where a non-homogeneous and enlarged fiber structure was observed, potentially bringing about heightened wettability. Such enhancement of wetting behavior could have been engendered through migration of the polar groups of the surfactant to the surface of the nanofibers during solidification [ 59 ]. Following this, strong hydrogen bond interactions between the surfactant and water molecules are expected.…”

Novel Polyvinyl Butyral/Monoacylglycerol Nanofibrous Membrane with Antifouling Activity

Monoacylglycerols (MAGs) have proven of great interest to the foodstuffs industry due to the promising antibacterial activity they show for controlling microbial contamination. Prior to this paper, this antibacterial agent had not been incorporated in a nanofibrous membrane. This study details convenient fabrication of nanofibrous membranes based on polyvinyl butyral (PVB) containing various concentrations of monocaprin (MAG 10) by an electrospinning process. Increasing the concentration of MAG 10 caused differences to appear in the shape of the nanofibers, in addition to which the level of wettability was heightened. Besides exhibiting antibacterial properties, the functional membranes demonstrated especially good antifouling activity. The novel and efficient nanofibrous membranes described have the potential to find eventual application in medical or environmental fields.

“… 31 Low ST helps the process as long as a low electric field is used. 32 It is important to clarify that ST is a function of the solvent used in the polymeric solution. 23 Fortunately, there are different ways to change the ST of the materials used, by using additives, like ionic liquids or organic/inorganic salts, while varying the solvent or the surfactants.…”
