High performance of graphene oxide (GO)-thiosemicarbazide (TSC) modified membrane for pervaporation desalination with TSC performed as a novel cross-linker

Composite 2D Material-Based Pervaporation Membranes for Liquid Separation: A Review

“…With the same idea of Qian et al [ 59 ] toward the interlayer spacing regulation in GO via crosslinking, Jiao et al [ 62 ] evaluated the effect of using a novel crosslinking agent, such as thiosemicarbazide, into GO membranes. The interaction of thiosemicarbazide and GO produced a covalent crosslinking reaction, allowing for the final composite membranes to exhibit a negative charge.…”

“…The ultrathin membranes (138 nm) demonstrated complete salt rejection (99.9%) with a flux of over 91 kg•m −2 h −1 (10% salt solution at 85 °C). In a different work, bifunctional poly(dopamine-ethylenediamine) and a GO scaffold membrane were fabricated and chemically crosslinked by glutaraldehyde by Wang et al [60], who proved that the GO backbone and hydrophilic functionalities allowed for unimpeded wa- With the same idea of Qian et al [59] toward the interlayer spacing regulation in GO via crosslinking, Jiao et al [62] evaluated the effect of using a novel crosslinking agent, such as thiosemicarbazide, into GO membranes.
