“…The high hydrophobicity and mechanical stability are among the most important aspects in designing membranes for DCMD applications. [23][24][25] Its excellent stability and mechanical strength, hydrophobicity, low thermal conductivity compared to PTFE and PVDF is very promising for variety of MD applications. In addition, the fabrication of SBS membranes is more cost and energy effective compared to the available PTFE and PVDF membranes.…”

In this study, styrene-butadiene-styrene (SBS) was used to develop a novel functionalized electrospun membrane for the effective treatment of heavy metals in direct contact membrane distillation (DCMD) applications. Functionalization was achieved by the addition (doping) of the super hydrophobic Al 2 O 3 nanoparticles (Al NPs) within the matrix of the membrane during electrospinning. Neat (pristine nondoped) and doped SBS membranes were tested. The performance of the SBS membranes were also compared with fabricated polyvinylidene fluoride membranes with and without doping with Al NPs. The membrane characteristics were tested via Fourier transform infrared, scanning electron microscopy, pore size, and porosity investigations. The wettability of the membranes was investigated with respect to the liquid entry pressure (LEP) and contact angle. The performance of the membranes was tested in a DCMD setting for its ability to treat water containing salt (NaCl) and heavy metals (Cr (VI), Cd, Pb) in various concentration in a single and multicomponent systems. The SBS member exhibited excellent hydrophobicity characteristics such as a high LEP (16.87 psi) and contact angle (141 ± 2 ). It also had superior permeate flux rate compared to the other prepared membranes (54.4 LMH). The addition of the Al 2 O 3 nanoparticles enhance the performance of the membranes substantially.Slight decline in the flux was observed after 14 hours of continuous operating time that could be attributed to agglomeration, adsorption, or temperature polarization effects. The SBS AL NPs membranes also demonstrated excellent flux for saline solutions of varied concentrations with 99% salt rejection.

“…In our previous study, the addition of graphene (Gr) nanosheets to the SBS membrane matrix was shown to improve the membrane hydrophobicity and PV performance in removal of an organic compound from water . Therefore, in the separation of organic compounds from water, membrane hydrophobicity is an important factor that brings about increased selectivity .…”

Styrene-butadiene-styrene (SBS) membranes incorporated with carbon black (CB) were prepared and investigated for pervaporation (PV) removal of 1,2,4-trimethylbenzene (TMB) from its aqueous solution. The influence of CB concentration on membrane properties was assessed by applying field emission scanning electron microscopy, differential scanning calorimetry, thermogravimetric analysis, X-ray diffraction, Fourier transform infrared spectroscopy, and tensile test. Characterization of the prepared membranes implied increased water contact angles at higher CB concentrations. Moreover, membrane swelling was constant zero for all the membranes. Performance of the prepared membranes in PV separation of a volatile organic compound (1,2,4-TMB) from water was studied. The SBS/CB nanocomposite membranes revealed higher separation factor and PV separation index (PSI) compared to pure SBS membrane because of the CB hydrophobic nature. The separation factor and PSI of the nanocomposite membrane loaded with 1 wt. % CB were 3.6 and 1.8 times more than those of the neat SBS membrane, respectively. The membrane obtained at this appropriate CB concentration provided the total flux of 735 g/m 2 h, separation factor of 950, and PSI of 700,000 g/m 2 h. POLYM. ENG.
