网页Millipore polypropylene filters are constructed of 100% virgin polypropylene media. They are ideally suited for general clarifying and prefiltration applications including solvents, deionized water and bioburden reduction. They also provide broad thermal compatibility. The prefilters provide high particle retention, high dirt holding capacity
网页Hydrogels formed via such hydrophobic interactions in micellar solutions exhibit unique properties such as a high stretchability (up to 5,000 %), high mechanical strength (up to 1.7 MPa tensile stress), and complete autonomous self-healing. Fig. 2.
网页2021年11月1日 · Porous membranes having a particular wetting characteristic, hydrophobic or hydrophilic, are used for nondispersive membrane solvent extraction (MSX)
网页2021年8月1日 · The average flux through the hydrophobic membrane for the first 105 days of operation was of 1.1 ± 0.7 g N m −2 h −1, showing a high fluctuation, concomitant to a pH value of the cathodic bulk solution of 11 ± 1 and a N
网页2022年12月27日 · The scarcity of freshwater is one of the challenges faced by humanity today. Solar desalination technology is gaining increasing attention due to its environmental friendliness and sustainability. However, the service life of the evaporator is significantly reduced by the problem of salt deposition during the evaporation process. In this work, a
网页2019年4月5日 · Hydrophilic modification was conducted by dipping PP membrane in nitric acid and sulfuric acid. However, the nascent PP membrane would float on the surface of nitric and sulfuric acid solution due to the strong hydrophobicity of PP membrane, thus resist the acids to reach the pores and lumen side of the membrane [ 1 ].
网页2021年11月1日 · This is because that the electrospun hollow fiber membrane using the Pullulan solution and PTFE emulsion as the spinning aqueous solution has a high porosity and membrane flux. Meanwhile, due to the unique solvent stability and abundant surface roughness of PTFE [51] , [52] , the self-made hollow fiber membrane still has a stable

网页These extremely strong, hydrophobic* (PVP-free), polycarbonate track etch (PCTE) membrane filters minimize extractables and are our lowest non-specific binding membranes; these properties make them ideal for chemotaxis, small-particle capture & analysis, and venting applications. Our hydrophobic PCTE membranes are produced
网页Hydrophobic ceramic membranes are commonly prepared by chemical modification. Besides using different types of chemicals, the membrane surface is roughened to
网页Most of these materials are, however, relatively hydrophobic, but some can be mixed with additives during fabrication which then allows the use of these membranes for aqueous filtration. Typical polymers used to increase the wettability of the membrane material include polyvinylpyrrolidone (PVP) and methacrylates ( Puspitasari, Granville, Le-Clech, & Chen,
