More importantly, the hydrophobic tails of SDS tend to form hydrophobic−hydrophobic interactions with PTFE, leading to the adhesion on the membrane surface and pore surface as depicted in Fig. 7. As a result, the hydrophilic head of SDS allows the intrusion of the saline solution, leading to the membrane wetting phenomenon ( Fig. 7 a).

Foxx Life Sciences. EZFlow 25mm, 47mm, and 90mm membrane disc filters are used to retain particles or microorganisms by surface capture. The membrane disc filters are available in 0.22µm or 0.45µm pore sizes. The Hydrophobic PTFE membrane is bonded to a polypropylene support and due to its extreme chemical.

The main objective was to test the ammonia stripping technology using two types of hydrophobic membrane materials, polypropylene (PP) and polytetrafluoroethylene (PTFE) at pilot scale and carry out: (i) Process modification for NH 3 molecule removal and (ii) product characterization from the process. The results demonstrate that PP membranes

Dec 15, 2019 · Among these hydrophobic membranes, the PTFE membrane has desirable characteristics, such as excellent hydrophobicity due to the low surface energy of about 20 mN/m, high membrane porosity and strong chemical stability with a melting point of about 327 °C (Zhang et al., 2019a; Zhao et al., 2018).

Feb 01, 2021 · Li et al. [ 13] designed hydrophobic fibrous membranes using PU and fluorinated polyurethane (FPU) as the raw polymers. Ultimately, the PU/FPU membranes exhibited a good water vapor transmission rate of 11.9 kg/ (m 2 d) and the hydrostatic pressure of 86 kPa. Zhao et al. [ 14] used AgNO 3 to prepare PU/C4FPU/AgNO 3 WBFMs.

Apr 20, 2009 · PVDF–PTFE membranes spun at an air gap of 4 cm and with 50 wt.% particle loading demonstrate an optimal separation performance of 40.4 kg/m 2 h permeation flux as well as ∼99.8% salt rejection at 80 °C. This performance is comparable or even higher than the commercial hydrophobic membranes for DCMD studies.

The hydrophobic PTFE membrane filters are made of polytetra-fluorethylene (PTFE) only and are therefore permanently hydrophobic. Unlike hydrophilic filter types, they are not wetted by air humidity.

For use with Dolomite’s Membrane Chip and Membrane Chip Interface for effective separation of organic and aqueous solutions, in-line filtration and liquid-liquid contracting, the hydrophobic PTFE membranes offer excellent chemical resistance with a pore size of 0.2 µm.
