Carbon nanotube blended polyethersulfone membranes for fouling control in water treatment

The Separation Power of Nanotubes in Membranes: A Review

“…Mitigation of membrane fouling is another objective, which has been described by Celik et al [173]. They show that MWCNT/polyethersulfone blend membranes have a better fouling resistance than bare membranes.…”

Nanomembrane Materials Based on Polymer Blends

“…Another category is thin-film nanocomposites (TFNs), which is a composite membrane with deposited and cross-linked nanomaterials on their surface [51,52]. In spite of the type and amount of nanoparticles in the modified polymer membranes, their structure is generally asymmetrical and comprises a dense skin layer and a porous supporting layer [53,54]. The differences between the structure of nanomembranes and conventional polymer membranes result from the different size and quantity of pores, and also the thickness of the skin layer formed [51].…”

Basic RF Characteristics of Fishbone-Type Transmission Line Employing Comb-Type Ground Plane (FTLCGP) on PES Substrate for Use in Flexible Passive Circuits

“…2, we can see that an increase in the length of a PMS results in an enhancement of the periodical shunt capacitance C PMS , due to an increase to the open stub length, and an enhancement of coupling capacitance C b , due to an increase in the coupling area between a PMS and PGS. Therefore, the characteristic impedance of the FTLCGP, Z 0 , can be easily controlled by changing the length of the PMSs, because Z 0 depends on the periodic shunt capacitance and series inductance of the transmission line, as shown in (2). The dependence of Z 0 on the length of a PMS is shown in Fig.…”

“…Recently, RF applications of flexible electron devices have drawn attention due to the demand for the development of foldable wireless communication devices. Compared with other flexible materials, polyethersulfone (PES) showed better heat-resisting properties and higher transparency [2]- [3]. In addition, PES shows good waterresistant qualities [2].…”

“…Compared with other flexible materials, polyethersulfone (PES) showed better heat-resisting properties and higher transparency [2]- [3]. In addition, PES shows good waterresistant qualities [2]. For these reasons, PES has been employed in flexible Monolithic Microwave Integrated Circuits (MMICs) [4]- [5].…”
