“…Hollow fiber membranes have been used as an oxygenator and are usually obtained via a phase inversion process [ 191 , 192 ]. The commonly used polymers for hollow fiber membranes are hydrophobic polymers, such as polymethylpentene (PMP), polypropylene (PP), PDMS, polysulfone (PSf), polyethersulfone (PES), polyethylene (PE) and polyvinylidene fluoride (PVDF) [ 26 , 192 , 193 , 194 , 195 , 196 , 197 , 198 ]. Wang et al [ 194 ] reported the production of poly (4-methyl-1-pentene)/polypropylene (PMP/PP) thin film composite (TFC) with a PVA/PSS coating was anchored on the membrane surface via crosslinking and PDA binding for membrane oxygenator application.…”

Polymeric membranes are selective materials used in a wide range of applications that require separation processes, from water filtration and purification to industrial separations. Because of these materials’ remarkable properties, namely, selectivity, membranes are also used in a wide range of biomedical applications that require separations. Considering the fact that most organs (apart from the heart and brain) have separation processes associated with the physiological function (kidneys, lungs, intestines, stomach, etc.), technological solutions have been developed to replace the function of these organs with the help of polymer membranes. This review presents the main biomedical applications of polymer membranes, such as hemodialysis (for chronic kidney disease), membrane-based artificial oxygenators (for artificial lung), artificial liver, artificial pancreas, and membranes for osseointegration and drug delivery systems based on membranes.

“…18) can be employed to evaluate the blood oxygenation performance of the membrane. 65 Blood is first deoxygenated to venous oxygen saturation (70–80%) by flowing N 2 and CO 2 gas at a 10 : 1 ratio to the air side of the membrane cell, and then it is streamed serially through the cross-flow circuit with the use of a peristaltic pump. The blood reservoir is adjusted to a temperature of 36 °C.…”

“…Surfaces with superamphiphobic properties, which can repel both water and organic liquid droplets, are more desirable in industrial fields − and are further widely applied in a number of fields including oil spill resistance, − chemical shielding, − and antifouling, − which will find more actual applications in protecting transformer components during the use and storage process. Xu et al prepared a 1060 aluminum alloy mesh with superamphiphobicity by the chemical deposition method, only relying on AgNO 3 solution, and the fabricated samples could display excellent corrosion resistance and self-cleaning properties .…”

The iron core and heat sink in a mining transformer are susceptible to damage from oil spills or the harsh mine environment; the deterioration of oil products in the underground environment and transformers produce massive amounts of harmful liquid substances, which may lead to unnecessary economic losses in drilling engineering. To overcome this issue, a convenient and economical way to protect transformer components was developed. Herein, we proposed an air spray technology at room temperature for the preparation of antigreasy superamphiphobic coatings, which are suitable for bulk metallic glass transformer cores and ST13 heat sinks. The addition of polypyrrole powder effectively improves the thermal conductivity and specific heat of the coating in the range of 50–70 °C. More importantly, the fabricated coating has excellent repellency to liquids, such as water, ethylene glycerol, hexadecane, and rapeseed oil. Meanwhile, the coating has excellent physical and chemical resistance and outstanding antifouling features, which provide a feasible solution for combating grease pollution and corrosion in the mine environment. Taking multifaceted stability into consideration, this work contributes to enhancing the application of superamphiphobic coatings in the fields of protecting transformer components in the harsh environment or during transformer operation faults.
