AbstractHigh performance plastic resins PEK-C, PES, PEI and PSU were mixed with organoclay CH3 ( CH2)(17) (CH3)(3)N-3(+) -Montmorillonite in solution. The XRD results revealed that the PEK-C and PES were very easy to intercalate into the clay and drove the clay to exfoliate, as a result, exfoliated polymer/clay nanocomposites were obtained. On the contray, PEI and PSU could not intercalate into the clay. The possible reasons caused these different results might be that the interaction between the former two polymers and clay were strong while the interaction between the latter two polymers and clay were weak. The T(g)s of PEK-C/clay and PES/clay nanocomposites were 210degreesC and 229degreesC, much lower than that of pure PEK-C and PES, which were 227degreesC and 237degreesC, respectively. But the decomposing temperatures T-d of PEK-C and PES rose from 469degreesC to 507degreesC and from 514degreesC to 579degreesC after mixed with clay, increased 38degreesC and 65degreesC, respectively. For the polymer PEI and PSU, which could not intercalate into the clay. both their T-g and T-d changed little after mixed with the clay. The positron annihilation life time spectroscopy results indicated that larger free volumes formed as PEK-C combined with clay, which was supposed to be responsible for the decreases of its T-g.
