有机杂化阻尼材料动态力学性能的影响因素探讨

高分子阻尼材料作为一类环保功能材料,将向高性能、宽温域的方向发展。传统的阻尼改性方法(如共混、共聚、无机杂化等)及近年来发展起来的互穿聚合物网络和添加压电陶瓷等研究手段都存在一定的局限性。新近开发的利用有机小分子与极性高聚物形成杂化体的方法所得到的阻尼材料的性能非常突出,是一种很有前途的阻尼改性新方法。本文在对现有的二元、三元杂化体系进行分析对比的基础上,对影响有机杂化阻尼材料动态力学性能的因素进行了探讨,为今后该领域的研究工作提供参考。

STUDY OF INFLUENCE FACTORS ON DYNAMIC MECHANICAL PROPERTIES OF ORGANIC HYBRID DAMPING MATERIALS

As environment-friendly functional materials,polymer damping materials will follow a tendency of high performance and broad glass transition region.However,the traditional damping modification methods such as polymer blends,copolymer,inorganic hybrids,etc.as well as recently developed means of interpenetrating polymer network(IPN) and conductive-piezoelectric damping all have certain limitations.The latest organic hybrid damping materials composed of organic small molecular substances and polar polymers exhibit excellent damping properties.Thus,the new mean of organic hybrid has been considered to be a promising damping modification method.Based on the analysis and comparison of some reported binary and ternary organic hybrid systems,this paper discusses various influence factors on dynamic mechanical properties of organic hybrid damping materials and provides some references for further researches in this field.
