IR spectroscopic and thermogravimetric study of state of water in MGA-95 cellulose acetate membrane
The state of water in the MGA-95 composite cellulose acetate membrane has been investigated using the techniques of IR spectroscopy and thermogravimetry. It has been concluded that water, acting a plasticizer, structures macromolecules of the amorphous phase of the cellulose acetate membrane and promotes its transition to a liquid crystal phase forming additional capillary spaces.
