Abstract
Summary: The changes in both local intercalated structures and spatial distribution states of organoclays (OC) in rubber/clay nanocomposites (RCNs) caused by vulcanization were monitored by using WAXD and TEM, and the corresponding mechanism was studied. It was first discovered that the pressure was the critical factor determining the final microstructures of cured RCNs. The cured RCNs with fine dispersion could be obtained through vulcanization under atmospheric pressure.
