“…These nanofiber webs can have several applications, including medical [1][2][3], pharmaceutical [4,5], sensor [6], filtering [7][8][9], clothing, construction engineering applications as well as composites [10,11]. Nanofibers have unique properties such as high surface to mass ratio and flexibility that makes possible to use them as reinforcement of composites.…”

Abstract. The present paper investigates how the presence of nanofiber interleaves affects the compressibility of the layup during manufacturing of the composites and hence determining the theoretically attainable fiber volume fraction at the given processing pressure. The results show that up to the interleave areal density of 10 g/m 2 per nanofiber layer the decrease of fiber volume fraction does not exceed 3% for a laminate of carbon fiber woven fabric. Interleaves inside a fabric laminate are more compressible than a plain electrospun veil. It can be explained as the nanofibers penetrate between the carbon fibers when applying compression during composite manufacturing. It can be stated that there is a strong interference between the interleaves and the carbon reinforcement, which can lead to effective toughness improvement of the composite without significant alteration of fiber volume content.

“…This irreversible fouling contributed to the increase of the total fouling resistance of the membrane surface during five (5) hours of peat water filtration. Furthermore, the low pH of the peat water solution also contributed to the enhancement of organic matter hydrophobicity [27,28]. This initiated further interaction between the organic matter in the bulk solution and the organic matter deposited on the membrane surface.…”

Abstract. Modification of polysulfone ultrafiltration membrane was conducted by blending polysulfone with PEG400 and acetone as additives. The influence of each additive on the resulted membrane morphology and fouling characteristics were investigated. The experimental results showed that the hydrophilicity of the polysulfone membrane was improved by the increase of PEG400 in the polysulfone membrane. The water contact angle of the membrane was decreased from 76.1° to 38.31° when 35 %wt of PEG400 was added into the polysulfone solution, while the water content of the membrane was increased by around 38%. The high concentration of PEG400 in the polysulfone solution led to the formation of longer finger-like cavities in the membrane structure and resulted in a thicker membrane skin layer. The high concentration of PEG400 also contributed to the increase in hydraulic resistance of the membrane due to organic matter fouling. This problem could be minimized by the addition of acetone into the polysulfone solution, which resulted in a lower fouling resistance of organic matter during up to five hours of peat water filtration.

“…2. Further, surface modification of the membrane with anionic/acidic and neutral highly hydrophilic functional groups has been demonstrated to prevent/minimize DOM interaction with the membrane surface [21][22][23][24] in several recent literature studies. M&PT own in-house study has highlighted the difference between the surface interaction of a bare Al 2 O 3 membrane and surface modified membrane (SMM) Al 2 O 3 in a side-by-side study shown in Fig.…”
