“…Images were than taken using a camera. To determine contact angle, curve-fitting analysis was carried out on captured images using CAM 2008 software (Delcam, Birmingham, England, UK) [46]. Static contact angles were measured at four different positions on each membrane surface and by averaging these contact angles, the final water contact angle was obtained for pure and hybrid PES membranes.…”

“…For water retention analysis, 1 g of pure PES and hybrid membranes were soaked in distilled water for 24 h. The wet weight of each membrane was recorded. Membranes were then oven dried for 12 h. Dry weight of each membrane was recorded afterward [46]. Based on these measurements, the percentage water content of each membrane was calculated by using the following equation and five readings were recorded to ensure the accuracy of results.…”

“…The filtrate assembly was arranged at room temperature with constant pressure of 60 cm-hg for 120 min. A sample of 0.025 m 2 of membrane was tested under this assembly [46]. Membrane flux values provide an idea about the efforts required to produce the permeate and to compare the initial performance of the pure and hybrid membranes.…”

Plant phytochemicals have potential decontaminating properties, however, their role in the amelioration of hydrophobic water filtration membranes have not been elucidated yet. In this work, phytochemicals (i.e., cannabinoids (C) and terpenes (T) from C. sativa) were revealed for their antibacterial activity against different Gram-positive and Gram-negative bacteria. As such, a synergistic relationship was observed between the two against all strains. These phytochemicals individually and in combination were used to prepare polyethersulfone (PES) hybrid membranes. Membrane characterizations were carried out using scanning electron microscopy, Fourier transform infrared spectroscopy, energy-dispersive X-ray spectroscopy. Moreover, contact angle, water retention, surface roughness, mechanical testing, and X-ray florescence analysis were also carried out. According to results, the CT-PES hybrid membrane exhibited the lowest contact angle (40°), the highest water retention (70%), and smallest average pore size (0.04 µm). The hybrid membrane also exhibited improved water flux with no surface leaching. Quantitative bacterial decline analysis of the CT-PES hybrid membranes confirmed an effective antibacterial performance against Gram-positive and Gram-negative bacteria. The results of this study established cannabinoids and terpenes as an inexpensive solution for PES membrane surface modification. These hybrid membranes can be easily deployed at an industrial scale for water filtration purposes.

“…Thus, the idea of membranes having both polymeric substrate as well as inorganic filler came in existence, which can overcome the above-mentioned limitations to a large extent. There are different studies having various fillers like Fe 3 O 4 nanoparticles (Alam et al 2013;Chan et al 2015;Ghaemi et al 2015;Bagheripour et al 2016;Mondal et al 2017), oxidized multiwalled nanotubes (Yin et al 2013;Celik et al 2011a, b), TiO 2 nanoparticles (Luo et al 2005;Rahimpour et al 2012;Esfahani et al 2015;Mbuli et al 2018;Farahani and Vatanpour 2018), functionalized MWCNT (Qiu et al 2009;Liu et al 2018;Benally et al 2018;Ho et al 2017;Lee et al 2016), silver nanoparticles (Taurozzi et al 2008;Zhang et al 2012;Sonawane et al 2017), modified silica nanoparticle (Farahani and Vatanpour 2018;Huang et al 2017;Martín et al 2016), chitosan/zinc oxide nanoparticles (Munnawar et al 2017;Ahmad et al 2017;Elizalde et al 2018), beta cyclodextrin-polyurethane (Adams et al 2014), graphene oxide (Ho et al 2017;Chai et al 2017;Karim et al 2017;Mukherjee et al 2016;Karkooti et al 2018), manganese oxide and alumina nanoparticles (Delavara et al 2017;Gohari et al 2014), zeolites (Liu et al 2014;Grabczyk et al 2017;Amiri et al 2017), attapulgite…”

Understanding the morphology of MWCNT/PES mixed-matrix membranes using SANS: interpretation and rejection performance

et al. 2019

We describe the relationship between the morphology and rejection performance by the mixed-matrix membranes as a unique class of high water flux nanofiltration membranes comprising polyethersulfone/functionalized multiwalled carbon nanotubes (PES/f-MWCNTs). These membranes contain aligned MWCNTs uniformly distributed inside a PES matrix prepared using conventional phase-inversion technique. The small-angle neutron scattering analysis confirmed the high porosity and uniformity among of the pores of CNTs in the membranes. The frictionless water transport from vertically oriented f-MWCNTs were verified to facilitate remarkable enhancement in the water flux through the membranes. The water transportation speed, as well as rejection, of selected heavy metals increases nearly about 3 times and 2-3.5 times, respectively, than the pristine PES membrane, depending upon CNTs loading. Low working pressure and good retention properties make these membranes to be an ideal for the application of highly efficient filtration units.Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

“…The present study modified complex polyelectrolyte membranes with nanoparticles to reduce fouling effects in the membrane. The impregnation of nanoparticles into a membrane is expected to degrade pollutants trapped on the membrane surface, thus preventing fouling [22][23][24][25].…”

A membrane is a thin lining material which can selectively transport the mass of a component as a result of thrust force and the chemical and physical properties between the membrane and permeated compound [1]. Membranes are often used for purification, in processes such as haemodialysis [2], biodiesel purification [3] and waste water purification [4]. Compared with other waste-water treatment methods such as adsorption and coagulation, a membrane is effective because it saves time, is continuous and conserves energy [5]. However, this method has some drawbacks, one of which is fouling [6,7]. Some studies have been conducted into ways to prevent fouling in membrane-based filtration processes, including research into bioreactor membranes in which microorganisms act to degrade contaminants, thus minimizing fouling in the filtration process and improving the efficiency of the membranes used [8].
