    • The GaussAmp function of Origin software, I = I0 + Ae-(q-q*)2/2w2 was used to fit the primary peak to obtain w. Here, I and I0 represent the intensity along the curve and base intensity, respec tively, and q* represents the position of maximum I (i.e., peak position) and FWHM; w1 was found as w1 = 2w(ln 4)1/2

    • The volume fraction vs interplanar spacing (ℙp, d) data for the three additives was fitted to the equation d = Aℙp-β to find the three β values. A represents the hypothetical value of d for neat F108 because neat F108 is disordered. However, since the value of A should be the same in all the three cases, A was not fitted, but a value for it was determined such that the value of S-the sum of the sums of square of residuals for each data set-was minimized. Mathematically, S is denoted as S = σall additivesσeach, additive- (Awp-β - d)2. The inner summation represents the residuals for each additive's data set (i.e., the difference between calculated and experimental values of d) while the outer summation represents summation of residuals obtained for data sets of each additive
