聚二甲基硅氧烷（PDMS）是最常用的有机硅弹性体，具有广泛的应用，包括微流体和微接触印刷。目前有各种类型的PDMS，并且它们的本体材料性质已经被广泛研究。然而，由于很少在一项研究中比较这些特性，因此通常不清楚报告数据的巨大差异是由于方法的差异还是由于其内在特征。在这里，我们报告四种不同的PDMS聚合物，即Sylgard-184，CY 52 -276，SIM-360和KE-1606的粘弹性能和光学性能。我们的研究结果表明，所有的PDMSs是高弹性的，而不是粘弹性在标准的基础/固化剂的比例，其量化的弹性模量，折射率，和光学清洁度是相似的，但不同的幅度。
Polydimethylsiloxane (PDMS) is the most commonly used silicone elastomer with a wide range of applications including microfluidics and microcontact printing. Various types of PDMS are currently available, and their bulk material properties have been extensively investigated. However, because the properties are rarely compared in a single study, it is often unclear whether the large disparity of the reported data is attributable to the difference in methodology or to their intrinsic characteristics. Here we report on viscoelastic properties and optical properties of four different PDMS polymers, i.e. Sylgard-184, CY52-276, SIM-360, and KE-1606. Our results show that all the PDMSs are highly elastic rather than viscoelastic at the standard base/curing agent ratios, and their quantified elastic modulus, refractive index, and optical cleanness are similar but distinct in magnitude.
