Abstract

Schematic for the preparation of PAN/PVA membrane deposited on the stainless steel mesh modified by dilute PVA solution.

The Effect of Different Ratios of Malonic Acid to Plyvinylalcohol on Electrochemical and Mechanical Properties of Polyacrylonitrile Electrospun Separators in Lithium-Ion Batteries

“…Fig. 2 shows the high magnification of SEM image for the crosslinked membranes in which the bonding structures were formed among the adjacent fibers of PAN/PVA [41]. This change and creation of the network in Fig.…”

“…Tensile strength is directly related to the length of the polymer chains in terms of their length and how they are bonded to each other [10]. In the prepared samples, a substantial decrement in tensile strength occurred [44] by increasing the amount of PVA hydrophilic material to neat PAN, which had less tensile strength in comparison to PAN [41]. The polymer network of PAN/PVA/MA could be tailored into a threedimensional network structure at the molecular level, which would considerably enhance the strength for the whole membrane [43].…”

High filtration efficiency fluffy material: nano-fiber constructing gradient structure on recycled curved PET micro-fibers web

“…Micro/nano-fibers, nanoparticles and multi-layer hybrid structure are used for the designing of the gradient structure. Cheng et al [21] introduced a PAN/PVA multi-level structure filtration material via multi-jet electrospinning process, and its FE was up to 99.996% and ΔP reached 418 Pa for the testing media particles size of 300 nm.…”
