“…Zhao et al [20] used different wt.% of pluronic F127 in PES membranes and got higher lysozyme rejection and flux recovery ratio compared to plain membrane. In another study, Loh et al [21] reported the effect of different pluronic block copolymers. With the highest wt.% of 10 for pluronic F127, they got the highest water permeability of 113.8 L/m 2 h bar and the lowest MWCO of 9 kDa.…”

“…The Pluronic additive (PEO-PPO-PEO) segregated during phase inversion process to the polymer/water interface because of the low interfacial energy between the water and hydrophilic segment, as the water-insoluble, hydrophobic segment of the copolymer promptly anchored in the polymer matrix. [14]. The possible reason is that Pluronic f127 is perfect surfactant, as the surface chemistry of Pluronic F127/PES blend membrane might be reconstructed to reduce the interfacial free energy [15].…”

“…Chao et al [13] studied the effect of 1 to 9% of pluronic on membrane morphology and found that the water flux increased as well as pores and porosity. Ng et al [19] found that 1.71 % of polyvinyl alcohol (PVA) is a significant composition to achieve high salt rejection, while Loh et al [14] investigated systematically the effect of adding 5, 10 and 15% of pluronic on pore forming of PES membrane and it was found that the best composition is at 10% as it achieved the highest pure water flux. On the other side, different composition of additives added to the solution could give a significant impact on the mechanical properties of the synthesized membrane as reported by Ng et al [19].…”

“…Thus the aim of this study was to fabricate NF membranes from pure PES and PES blended with Pluronic F127 in 1.71 and 5 % as reported in [14,19] via phase inversion method. Next these membranes were characterized to investigate the pure water flux (PWF), contact angle, separation performance of xylitol mixture solution and the rejection test of xylitol mixture solution.…”

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.

“…Various polymer materials have been used for UF membrane preparation, such as cellulose acetate (CA) [5], polysufone (PSf) [6], polyethersulfone (PES) [7,8] and poly(vinylidene fluoride) (PVDF) [9]. Nevertheless, most commercially available polymeric ultrafiltration membranes could hardly be resistant to high temperature above 80 • C. It has sparked great interest in developing temperature-resistant membranes to be used for dealing with hot streams such as textile bleaching effluents, dyeing industry wastewater free of strict temperature control [10,11].…”
