关键字：EVM/PLA; Damping property; Polyols; Heat treatment
摘要：The effects of heat treatment on the damping ability of polyol modified EVM/PLA blends were investigated by TGA, XRD and DMA. The results showed that the damping of EVM/PLA blends was reduced after heat treatment due to further crosslinking of the EVM and an increase in the degree of crystallization of the PLA phase. After heat treatment, an EVM/PLA blend modified with 10 phr polyol exhibited an effective damping temperature range which was reduced from 103.8 degrees C to 44.8 degrees C. The effective damping temperature range of an EVM/PLA blend modified with 30 phr polyol decreased after heat treatment from 183.3 degrees C to 103.9 degrees C. Polyols hinder the crystallization of PLA and thus improve the damping of EVM/PLA blends. (C) 2014 Elsevier Ltd. All rights reserved.
