Barrier Film

Most gas barrier films produce cracks that lead to a significant loss of gas barrier integrity when strain is applied. In order to fabricate stretchable gas barrier films with low water permeability and high endurance after stretching, we used polydiallydimethylammonium (PDDA) mixed with graphene oxide (GO) and poly (vinyl alcohol) (PVA) mixed with montmorillonite (MMT). These films were manufactured by layer-by-layer assembly on an Ecoflex/polydimethylsiloxane (PDMS) substrate with pre-strain applied. A total of 30 layers of PDDA (GO)/PVA (MMT) coated on the substrate exhibited a low water vapor transmission rate of 2.5 × 10−2 g/m2 day after 100 cycles of stretching (30% strain). In addition, they exhibited a high light transmittance of 86.54%. Thus, the prepared stretchable gas barrier film has potential applications as a barrier film in transparent and stretchable electronic devices.

In polymer nanocomposites, graphene is possibly the most promising nanofiller. Graphene produces impressive properties for polymers at very low filler content, which makes it highly interesting in building high-performance materials compared to other classes of polymer nanocomposites. Graphene-modified polymer nanocomposites have attracted much attention in scientific literature because of the need of superior materials with desirable properties such as electrical, mechanical, thermal, flame retardant, and gas barrier. Frequent studies have been attempted to produce graphene–polyamide (G-PA) nanocomposites with novel and improved properties. Based on this review, one can identify the synthesis technique and preparation for G-PA nanocomposites, which can further be useful in numerous applications.
