Performance of through-hole anodic aluminum oxide membrane as a separator for lithium-ion battery

Nanonet-structured poly(m-phenylene isophthalamide)–polyurethane membranes with enhanced thermostability and wettability for high power lithium ion batteries

“…The excellent wettability could be ascribed to capillary force of the pores in the PMIA-PU nanobrous membranes and the introduction of hydrophilic PMIA. 33,34 Moreover, the electrolyte uptakes of the PMIA-PU nanobrous membranes are in the range of 526.55-843.52% (Table 1), which are much higher than that of Celgard membrane. The improved electrolyte uptake is resulted from the high porosity and the strong affinity of the carboxy group (PMIA and PU) toward the carbonate ester group of solvent molecules.…”

The influence of the morphological characteristics of nanoporous anodic aluminium oxide (AAO) structures on capacitive touch sensor performance: a biological application

“…Among different research areas, the use of AAO in one-dimensional nanostructures is noteworthy, [5][6][7][8][9][10][11] as tubular membranes for hemodialysis, 12,13 membranes for gas separation, drug delivery and bone xation [14][15][16][17] energy storage devices, among others. [18][19][20][21] Recent work by several authors 12,14 prove that nanostructured functional layers of signicantly enlarged surface areas for sensor applications can be made from thin porous alumina lms.…”

Massive, eco-friendly, and facile fabrication of multi-functional anodic aluminum oxides: application to nanoporous templates and sensing platforms

“…[1][2][3][4] Aer the report on the two-step anodization resulting in a distinct improvement of the structural periodicities over the extended spatial regime, 5,6 anodic aluminum oxides (AAOs) have been widely adopted in diverse research elds, such as representative nanoporous templates for one-dimensional (1-dim.) nanostructures, [7][8][9][10][11][12][13] membrane lters, [14][15][16][17] evaporation/etching masks, 18-21 humidity sensors, [22][23][24][25][26][27][28] energy storage devices, [29][30][31][32] and bio-applications, [33][34][35][36] etc. These applications excluding surface treatments require AAOs with freestanding forms, i.e., separation from aluminum (Al) substrate, thus various strategies have been developed in the viewpoints of not only AAO fabricating (anodizing) but also AAO separating procedure.…”

“…Therefore, many efforts have been made for direct detachment of an AAO from the Al substrate, which can guarantee a reusability of the remaining Al substrate, by reversing polarity of the anodic voltage, 14,60 or applying a pulse-type anodic voltage. 29,58,59,61,62 The former strategy took too much time (e.g., 12-24 h), 60 and details of the detaching mechanism were not fully understood. Recently, Choudhary and Szalai reported on thickness-dependent behavior of a cathodic delamination of an AAO in nitric acid electrolyte and accumulation of the texturing effects.…”
