摘要：

Preparation of tannin gels was attempted by means of enzyme-mimetic reaction of condensed tannin without use of crosslinking agent. The gelation of condensed tannin was performed in the presence of H2O2 catalyzed by hematin of a ferriprotoporphyrin complex in water. The compressive measurements of the gels obtained by the 30-50 wt% concentrations of the tannin using 0.20-0.50 ml of 30 w/v% H2O2 aq. were examined. There is a tendency for the compressive properties of the gels obtained from the higher concentrations of the tannin and the larger amounts of H2O2 to be superior. The obtained gel was characterized by means of IR spectroscopy. Moreover, the obtained tannin gel was compatibilized with natural rubber to form a composite material.
