Transparent polyimide/graphene oxide nanocomposite with improved moisture barrier property

Layer-by-layer assembled graphene oxide films and barrier properties of thermally reduced graphene oxide membranes

“…Therefore, the intensity ratio of I D /I G provides direct evidence of the degree of functionalization [21,22]. pect-ratio of graphene multilayers can maximize the diffusion length of gaseous molecules through the composites; in what is called a "tortuous path" [23,24]. Therefore, PI composites with rGO and rAPGO should exhibit lower OTR values than that of pure PI due to the barrier effect of the graphene film on the PI surface.…”

Effect of graphene on polar and nonpolar rubber matrices

“…One of the easily observable advantage of GSD over conventional fillers is that, GSD requires only small concentration (≤ 0.1 phr) for reinforcing virgin elastomers for elastomeric/GSD composites with substantial properties (Boland et al 2014;Tan et al2008;Tseng et al 2012;Wei, et al 2014), whereas the conventional fillers such as; carbon blacks (CB), and nanoclays requires enormous loading level (≥ 5~20phr) to attain equivalent properties as the case of GSD based systems (Choi et al 2005;Hong et al 2007). …”

Effects of Graphene Monolayer Coating on the Optical Performance of Remote Phosphors

“…It has previously been reported that, by increasing the exposure time in 100% humidity condition, the weight of the samples increases due to water absorption. 24 The amount of absorbed water in the polymer is measured by the following equation:…”

“…Monolayer graphene is a one-atom-thick carbon layer which has received great attention over the past few years [20][21][22][23][24][25][26] because of its high light transmittance, great thermal and electrical conductivities, outstanding thermal and photochemical stabilities, excellent mechanical strength, and exceptional stability against heat and light. Using a graphene coating, optical and thermal stabilities of BPA-PC can be improved.…”
