Abstract
The normal carbon black or oxidized carbon black was incorporated into polyisoprene rubber by a solution blend, then the blends were treated by a toluene to get carbon gels from the composites. Transmission electron microscopy (TEM) observation and NMR measurements were carried out for the gels. It was evident from TEM observation that the rubber gels with the thickness of 2-3nm developed homogeneously on the normal carbon black. Further, the thickness increased when the oxidized carbon black was utilized. NMR results revealed that the carbon gel from normal carbon black was composed of soft and hard rubber phases. An additional phase (intermediate phase) was observed in the carbon gel from oxidized carbon black. Although the amount of carbon gel was larger for oxidized carbon black than for normal carbon black, the increase was primarily dependent on the increase of the content of intermediate and soft rubber phases. Based on these results combined with the surface characterization of carbon black, the formation mechanism and structure of bound rubber were discussed.
