GISAXS FOR 2D SMART MEMBRANES

The proposal is focused on elaboration of basic principles for controlling the permeability of laminated two-dimensional membranes by external stimuli. Like a pore diameter in conventional mesoporous membranes, d-spacing in 2D membranes determines their permeance and selectivity, thus enabling variation of membrane’s separation performance with tuning their d-spacing by external stimuli. Utilization of the GISAXS technique is required due to typical ultralow thickness (20-100 nm) of 2D membrane selective layers. Experiment designed for determining the correlations between d-spacing of 2D smart membranes, type (electric or electromagnetic field) and power of external stimuli. Based on this analysis, the correlations between interlayer distance and substance permeance in 2D membranes will be established
