用自行设计制造的滑板式流变仪测量了聚丁烯(PB)和聚二甲基硅氧烷(PDMS)两种模型聚合物的高频(210 Hz线性)粘弹性能。利用已知的流变模型，将旋转平行平板流变仪获得的粘弹性测量外推到210赫兹的频率，以评估高频滑板流变仪的性能。外推数据和测量数据之间的良好一致性表明，滑板流变仪能够测量牛顿材料和剪切变稀材料的高频流变特性。
Abstract A newly designed and constructed sliding plate rheometer is used to measure the high frequency (210 Hz) linear viscoelastic properties of two model polymers: polybutene (PB) and polydimethylsiloxane (PDMS). Using well-known rheological models, extrapolations of the viscoelastic measurements obtained on a rotational parallel plate rheometer to a frequency of 210 Hz are used to assess the performance of the high frequency sliding plate rheometer. Good agreement between the extrapolated and measured data demonstrates the ability of the sliding plate rheometer to measure the high frequency rheological properties of both Newtonian and shear-thinning materials.
