Effect of blend ratio and coagulation bath temperature on the morphology, tensile strength and performance of cellulose acetate/poly(butylene succinate) membranes

Preparation and characterization of a novel hydrophilic PVDF/PVA/Al2O3 nanocomposite membrane for removal of As(V) from aqueous solutions

“…As the figure illustrates, there was a significant reduction in water contact angle from M‐1 to M‐3 (from 85.9 to 43.9°) due to the presence of PVA hydroxyl groups on the blend membranes’ surfaces. Similarly, the reduction in contact angle with PVA was reported in prior studies . However, the reduction in contact angle values is quite negligible after the M‐3.…”

“…In general, if the governing mechanism in membrane preparation be the liquid–liquid demixing, the membrane would be porous with sponge‐like structure and finger‐like pores. On the other side, it would be a dense membrane with low porosity with the solid–liquid mechanism . According to the SEM images, it is realized that the governing mechanism in membrane preparation has been the liquid–liquid demixing.…”

Advances in biopolymer-based membrane preparation and applications

“…However, the use of PBS for the fabrication of polymeric membranes has been limited due to its weak strength and poor mechanical resistance. In order to overcome this limitation, PBS is often blended to other polymers such as PES 126 and CA 127 .…”

Microfiltration and Ultrafiltration Membranes for Water Purification

“…Esterification of succinic acid and butanediol and subsequent polycondensation of the resultant oligomers lead to the formation of PBS. In recent studies, PBS has been combined with PES and CA for synthesis of blended membranes [61,62,63]. The blended membranes possessed lower crystallinity and demonstrated larger mechanical resistance than unmodified PBS membrane.…”
