フラーレン類/スチレン系熱可塑性エラストマー複合物の調製と物性

Abstract

Fullerenes are the carbon materials that only 60 or more carbon atoms are covalently bounded. Since such greatly unique materials were discovered，many researches of fullerenes have been carried out. On the other hand，the unique carbon soot (CS) is yielded at production of fullerene, but it is not really investigated. However, we think that the application of CS is extremely important from the perspective of fullerene research and of market expansion. In this study, we prepared the composites by adding CS to styrene block copolymer (SBC)，and then investigated the additional effect by measuring dynamic mechanical analysis (DMA), differential scanning calorimetry (DSC) and tensile properties. The tensile moduli of SBS composites were more improved with increasing CS content than that of SEBS composites. Additionally, in comparison with carbon black, a reinforcing effect of CS to SBC was high. The result of differential scanning calorimetry indicates that the decomposition temperature of CS/SBS composite increased about 30℃ by adding 20phr of CS.
