The gelation speeds and temperatures for decalin and paraffin differed significantly. In decalin, gel syneresis occurred by solvent flow from the gels accelerates crystallization, and dry gel films were prepared. In contrast, in paraffin, many nucleating points appeared immediately, and few syneresis occurred even after quenching to room temperature. To prepare dry gel films, paraffin was blotted with filter paper, and residual paraffin was removed in hexane. However, the small-angle X-ray scattering (SAXS) patterns from both films provided similar profiles indicating large crystalline lamellar stacking ensuring ultradrawing.
