With increasing LN4 content, the intensity of the
loss peaks for the soft phase, and the area under these
peaks enlarges, suggesting that the volume of
materials taking part in the interaction at this region
increases with LN4 content, i.e. intensification of
mixed phase. A continuous inclination of the plateau
region in G0 vs. T curves further implies the gradual
increase in a mixed phase that is softer, leading to a
decrease in the storage modulus.
