Properties Of Composites

Graphene oxide (GO) was incorporated to poly(vinyl alcohol) (PVA) to form GO/PVA composite nanofiber membranes with reinforced mechanical properties via electrospinning technology. The effect of exfoliated degree of GO and dispersion sate in the PVA polymer matrix on the morphology and mechanical properties of composites is studied, revealing that the functional side groups of GO can improve the dispersion and interfacial bonding between the GO and PVA matrix. In addition, it also demonstrates the GO/PVA nanofiber membranes with the significant enhanced mechanical properties (2.28-fold increase in tensile stress) are obtained at a low GO loading (0.3 wt%). Our strategy provides new opportunities for the PVA composite to be involved in other potential applications.
