It was found that the gelation mechanism of NC gels is similar to that of conventional gels made with organic cross-linker (OR gels). Namely, time-resolved DLS measurements captured all of the characteristic features of gelation at the threshold. This indicates that the gelation of NC gels is also classified to an ergode−nonergode transition. However, the size of the clusters at the gelation threshold is much larger than that of OR gels. This results in a significant depression of optical transmittance exclusively at the gelation threshold for NC gels. Partial scattering functions, i.e., two self-terms SPP(q) and SCC(q) and the corresponding cross-term SCP(q), were obtained by contrast-variation SANS, where P and C denote polymer and clay, respectively, and q is the magnitude of the scattering vector.
