Study on the Damping Properties of Multi-Layered Gradient Materials Based on Organic Hybrids

Abstract:

In this paper, the multi-layered gradient materials consisting of polarized polymers and small molecules were prepared and the damping properties were studied by DMA. The predicted and experimental results showed that, it was possible to obtain damping material with broad efficient damping range by two-layered hybrid materials, the value in the middle of two peaks could be improved by increasing the number of layers of the multi-layered hybrids and there was a higher minimum value. On the other hand, with increased number of the layers of the multi-layered hybrid materials, the temperature dependence of could be improved. For five-layered gradient materials, it was almost rectangular transition range with values for the area under the linear curve. Thus, it would be feasible in theory and experiment to broaden the efficient damping range by multi-layered gradient materials based on organic hybrids, which provided a new approach and solid basis for developing high performance damping materials with a broad and high damping range.
