Figure 5: Effect of Povacoat on the DSC curves and FTIR spectra of IMC-NIC (molar ratio = 1:1) physical mixture after solvent evaporation. Key: a) prepared by 4:1 (w/w) weight ratio of Povacoat: IMC-NIC and final volume ratio of 2:8 (v/v) water:ethanol; b) prepared by 4:1 (w/w) weight ratio of Povacoat: IMC-NIC and final volume ratio of 1:9 (v/v) water:ethanol; c) prepared by 2:1 (w/w) weight ratio of Povacoat: IMC-NIC and final volume ratio of 2:8 (v/v) water:ethanol; d) prepared by 2:1 (w/w) weight ratio of Povacoat: IMC-NIC and final volume ratio of 1:9 (v/v) water:ethanol.
