“…[4][5][6] A commonly used method to create pores in self-assembled block copolymer films is the etching of sacrificial domains or the extraction of an added homopolymer. [7][8][9] However, these methods require multiple and complicated steps to develop highly ordered nanoporous membranes. To overcome the complicated steps involved, we developed in the past a simple approach to produce nanoporous membranes by combining selfassembly of block copolymers and non-solvent induced phase separation (NIPS).…”

“…Selective etching by fuming nitric acid gives nanoporous PE membrane where nanopores are interconnected each other. [ 32 ] This nanoporous membrane has been successfully applied for implantable glucose sensor. [ 33 ] In this study, these homogeneous lamellar structures were utilized as precursors of nanoporous membranes.…”

Biaxial melt-drawing of blend films composed of ultra-high molecular weight polyethylene and normal molecular weight polyethylene produced a unique network structure consisting of 30-nm thick homogeneous folded chain crystals. Subsequent biaxial solid-drawing produced a nanoporous structure covering a large area of the membrane surface (120 mm × 120 mm). Effects of preparation parameters, including annealing and subsequent solid-drawing, on resultant nanoporous morphology are also testified to achieve the desirable membrane. The higher gas permeability coefficients of the nanoporous membranes indicate that these nanopores are interconnected along the thickness direction. Despite such excellent porosity, the tensile strength reached 30 MPa, which is similar to that for the initial non-porous film. Consistence of membrane porousness and robustness is highly desirable for various separation applications, including filtration, water purification, dialysis, and lithium-ion batteries.

The potential of polymeric nanostructures obtained by extruding polymer solutions through reusable anodic aluminum oxide (AAO) nanopores for the fabrication of nanostructures is investigated systematically to be able to unveil the potential impact of structure on cell culturing. Thus, nanostructured Na‐alginate and poly(vinyl alcohol) (PVA) polymers as well as blended alginate/PVA hydrogels are fabricated. Na‐alginate and PVA fibers with different dimensions can be obtained. By extruding Na‐alginate solutions into a non‐solvent also networks of uniform nanofibers (diameter <20 nm) are generated. PVA forms agglomerations of nanofibers and nanoparticles with diameter >100 nm. In addition, cell line‐dependent behavior of the cross‐linked PVA/alginate nanofibers is observed, which is characterized by reduced cell adhesion and cluster formation of PaTu 8988t cells on these blend nanofibers compared to normal cell adhesive behavior of NIH 3T3 cells.
