“…Uniform dispersion and distribution of nanoparticles is a tedious job, although it shows a promising approach to modify the PE to be used in membrane fabrication . Blending modification is usually used to achieve the desired functional properties along with the membrane preparation, therefore the preparation and modification processes can be accomplished in a single step and the membrane preparation process would remain unchanged (Rajabzadeh et al, 2009;Nady et al, 2011;Zhao et al, 2011;Zou et al, 2011). Hydrophilic polymers, such as polyethylene glycol (PEG) (Kim and Lee, 1998), sulfonated polycarbonate (SPC) (Masuelli et al, 2009), copolymer poly (ethylene-co-vinyl alcohol) (EVOH) (Fu et al, 2006) and perfluorosulfonic acid (PFSA) (Lang et al, 2007) were used as hydrophilic additive in membrane fabrication.…”

Porous asymmetric polyethersulfone (PES) hollow fiber membrane was fabricated via dry/wet spinning process. The spinning dope consisted of 18 wt.% PES in N-methyl-2-pyrrolidone (NMP) solvent. Distilled water was used as bore fluid to make hollow fiber membrane without inner skin layers. Then, a skin layer consisting of poly (4-vinyl pyridine), PVP, silicon rubber PDMS and silica nanoparticles (nanoSiO 2 ) was transferred to the PES substrate surface by means of a dip coating method, leading to a nanocomposite hollow fiber membrane. Investigation of the cross-section of the prepared membranes via scanning electronic microscopy (SEM) revealed a good adhesion between the top dense layer and the PES substrate. Moreover, tensile strength and ultimate elongation of the pristine membrane were increased 2.3 and 5 times, respectively, when the PVP/PDMS/nano-SiO 2 coating was formed on its outer surface. Finally, according to the results of gas permeation tests, the prepared nanocomposite membrane, with a CO 2 /CH 4 selectivity of 45 and CO 2 permeance of 102 GPU would be an attractive candidate for applications such as natural gas purification and control of anthropogenic carbon dioxide emissions.

“…Nanofiltration (NF) membrane has been targeted to be used by many researchers due to its molecular weight cut-off (MWCO) ranges from 200 -2000 g/mol [6] that will be suitable to purify xylitol (152.15 g/mol) [1,5]. To fabricate this NF membrane, polyethersulfone (PES) was reportedly used due to its advantages such as easy to synthesize, high chemical resistance and vast pH tolerance [7,8]. Further, PES arise an outstanding oxidative stability [9].…”

Obtaining high purity of xylitol is a stone corner in medicine industries. Many conventional techniques (crystallization and adsorption) were used for xylitol purification from fermentation media. Recently, membrane technology received a great attention due to its high performance in xylitol purification. Among renowned copolymers used for polymer blending to produce membranes, pluronic is receiving much attention due to its strong hydrophilic characteristic and could work as pore former and surface modifier. Polyethersulfone (PES) polymer has been reportedly used for polymer blending as it possesses mechanical and chemical stabilities. Therefore, this work demonstrates the preparation of nanofiltration (NF) membrane using: (1) PES and (2) PES blended with 1.71% and 5% of Pluronic (F127), via phase inversion method. All fabricated membranes were subjected to investigations such as contact angle for hydrophilicity and water and solution flux for membrane performance. The findings showed increasing in water flux from 24.6 L/m 2 .h to 70.2 L/m 2 .h as 5% of Pluronic added. Further, the hydrophilicity improved from 80.1 ± 1.93 o to 72 ±0.3 o and 67.6 ± 0.72 o when 1.71 and 5% of Pluronic F127 added respectively. Therefore, the addition of Pluronic f127 has a great impact on PES membrane for xylitol permeation.Keywords: polyethersulfone, pluronic F127, xylitol, NF membrane, purification Abstrak Memperoleh ketulenan yang tinggi bagi xilitol merupakan salah satu batu loncatan di dalam industri perubatan. Terdapat banyak teknik konvensional (penghabluran dan penjerapan) yang telah digunakan untuk penulenan xilitol daripada media penapaian. Baru-baru ini, teknologi membran banyak menarik perhatian dengan prestasinya yang bagus dalam penulenan xilitol. Antara kopolimer yang sering digunakan untuk campuran polimer dalam penghasilan membran adalah pluronik yang telah menerima perhatian kerana sifat hidrofiliknya dan boleh membantu dalam pembentukan liang serta pengubahsuai permukaan membran. Polimer polietersulfon (PES) telah dilaporkan digunakan untuk polimer campuran kerana ia mempunyai kestabilan mekanikal dan kimia. Oleh itu, kerja ini menunjukkan penyediaan membran penurasan-nano (NF) menggunakan: (1) PES dan (2) PES dicampur dengan 1.71% dan 5% Pluronik (f127), melalui kaedah fasa songsangan. Kesemua membran yang dihasilkan dicirikan menggunakan sudut sentuhan untuk sifat hidrofilik dan fluks air serta larutan bagi prestasi membran. Hasil kajian menunjukkan peningkatan dalam fluks air daripada 24.6 L/m 2 .h kepada 70.2 L/m 2 .h apabila 5% Pluronik F127 ditambah. Selanjutnya, sifat hidrofilik membran bertambah baik iaitu daripada 80.1 ± 1.93 o kepada 72 ± 0.3 o dan 67.6 ± 0.72 o apabila 1.71 dan 5% Pluronik F127 ditambah. Didapati penambahan Pluronik F127 memberi kesan yang besar ke atas membran PES untuk penyerapan xilitol.
