“…These films, less than 200 nm thick after reduction, exhibited an OTR below the detection limit under dry conditions and 0.021 cm 3 m ‐2 day ‐1 atm ‐1 at 100% RH. Graphene nanoplatelets were suspended in polyethylenimine by Gokhale et al who showed that the suspension could be layered with poly(acrylic acid) (PAA) to form both hydrogen‐bonded and electrostatically‐bonded assemblies that significantly reduced the oxygen permeability of PET . A similar concept was studied by Rajasekar et al using poly(diallyldimethylammonium chloride) alternated with graphene oxide dispersed in sulfonated polyvinylidene fluoride .…”

Layer-by-layer (LbL) assembly has emerged as the leading non-vacuum technology for the fabrication of transparent, super gas barrier films. The super gas barrier performance of LbL deposited films has been demonstrated in numerous studies, with a variety of polyelectrolytes, to rival that of metal and metal oxide-based barrier films. This Feature Article is a mini-review of LbL-based multilayer thin films with a 'nanobrick wall' microstructure comprising polymeric mortar and nano-platelet bricks that impart high gas barrier to otherwise permeable polymer substrates. These transparent, water-based thin films exhibit oxygen transmission rates below 5 × 10(-3) cm(3) m(-2) day(-1) atm(-1) and lower permeability than any other barrier material reported. In an effort to put this technology in the proper context, incumbent technologies such as metallized plastics, metal oxides, and flake-filled polymers are briefly reviewed.

“…Among the polymer/nanoplatelet assembly films with 10 bilayers, our PEI/GO film exhibited a considerably better oxygen barrier performance. The permeability of 17 the PEI/GO composite film in this study was three orders of magnitude lower than that of the GNP/polyelectrolyte multilayer [44] , two orders of magnitude lower relative to polyacrylamide/montmorillonite (MMT) [45] and PEI/MMT [46] , and 86.8% lower than PEI/GO [47] . Thus, LBL self-assembly was more effective than other techniques in fabricating gas barrier films, and the electric field further enhanced the self-assembly to produce ultrahigh gas barrier films.…”

“…Since it is deposited in the liquid, the surface profile of the substrate therefore has no limitation. For the past two decades, LBLDP has been extensively investigated for a broad range of applications, such as antireflection (AR) coating, 1,2 DNA detection and therapy, 3,4 smart drug delivery, 5-7 glucose biosensor, 8 flame retardant coating, 9 superhydrophobic coating, 10,11 cancer biosensor, 12 conductive oxygen barrier films, 13 in combination with graphene oxide to improve the work function of an indium-tin-oxide glass in a polymer solar cell, 14 and for the investigation of virus concentration and recovery in large volumes of water. 15 The deposition of the polyelectrolyte requires adequate time because the positively or negatively charged polyelectrolyte molecules repel each other.…”

In this investigation, the effect of deposition time (5, 60, or 300 s) on a double-sided antireflection (AR) coating done by layer-by-layer deposition of polyelectrolyte was determined. The different structures and transmittance of an AR coating induced by electric-field-assisted layer-by-layer deposition (ELBLD) (with voltage of 0.5, 5, 50, or 500 V) and normal deposition (with voltage of 0 V) were compared. The electric field was perpendicular to the glass surface. After 5.5 bilayers of PAH/PAA were fabricated, the film was exposed to an acidic treatment of HCl solution (pH 2.4) for 65 s, followed by a brief rinse ($15 s) in deionized water, blown dry with air, and heat treated at 220°C for 2 h. Regardless of whether the electric field was applied, the average transmittance of visible light of the AR coating was more than 96% except for the reduced transmittance because of the excessive deposition of polyelectrolyte at an applied voltage of 500 V and a deposition time of 300 s. Average transmittance of 97.68 ± 0.31% was obtained at normal deposition of 5.5 bilayers with deposition time of 60 s. The polyelectrolytes had a propensity to form larger particles or accumulate into bundles under ELBLD, which was detrimental to the transmittance of an AR coating. Therefore, at the same deposition time, transmittance values of ELBLD samples were slightly lower than those of normal deposition. In other words, in the overall performance, the AR films of normal deposition are superior to those of ELBLD. The blowing pressure applied to dry the coating had significant impact on the quality of the film.
