Polyvinylidene fluoride (PVDF) membranes containing hydrophobic graphene nanofillers were prepared and tested for membrane distillation applications. The nanofillers were obtained by a two-step process: 1st) chemical grafting of hydrophobic molecules, either octylamine (OA) or perfluoroctylamine (PFOA), to graphene oxide (GO) nanosheets, and 2nd) c...
Graphene oxide (GO)-enhanced membranes are being developed to solve major limitations in both reverse
osmosis (RO) and membrane distillation (MD) technologies, which include high electricity and thermal energy
consumption. This study performed, for the first time, a life cycle assessment to determine the effects of using
GO-enhanced membranes on th...
Membrane distillation (MD) is a useful method for the purification of difficult feedwaters but it cannot be applied in a range of industries due to pore wetting. In this work, graphene oxide (GO) laminate coatings are explored to overcome the pore wetting issues. Air gap MD (AGMD) configuration was considered, using a 35 g L⁻¹ NaCl solution with 15...
PIM-1 mixed matrix membranes (MMMs) were fabricated with polyhedral oligomeric silsesquioxane (POSS) and graphene oxide (GO) functionalized with POSS (GO-POSS), and tested for CO2/N2 (single gas) and CO2/CH4 (1:1, v:v gas mixture). The CO2 permeability of the best performing fresh MMM (containing 0.05 wt% GO-POSS) was ∼ 12000 Barrer, which is 69% h...
Membrane distillation (MD) is an emerging thermal-based membrane technology that has the capacity to treat a wide range of feed waters, including high salinity brines and wastewater. Compared with pressure-driven processes, MD has the following advantages: low electrical energy consumption, complete removal of non-volatile solutes and ambient opera...
Growing uncertainty in the future availability of freshwater sources has led to an increase in installations for
desalination of seawater. Reverse osmosis (RO), currently the most widely adopted technique, has caused
environmental concerns over the high associated greenhouse gas emissions and generation of large amounts of
chemicals-containing brin...
