0076257HarrisonThis IMR grant supports the acquisition of an extensional rheometer in the Chemical Engineering department at Clemson University. The instrument will support the research of two young and two midcareer scientists in the investigation of extensional viscosity in polymers and polymer blends. The study facilitated by this instrument will allow a more complete characterization of a broad class of materials and lead to the development of new materials engineered with particular extensional properties. The rheometer will also enable current and future students to study extensional properties and investigate the influence of these properties on materials processing. Examples of materials to be studied are highly entangled polymer solutions and melts, polymer blends, composite materials and suspensions.Plastics and rubbers have extraordinary properites when they are squeezed or stretched. Pulling them apart involves measures such as extensional viscosity which play a vital role in the mechanical properties of these materials. The instrument acquisition supported by this grant is to help study the mechanical propertis of these technologically critical materials.

0076257哈里森IMR资助支持克莱姆森大学化学工程系购买拉伸流变仪。 该仪器将支持两名年轻和两名职业中期科学家在聚合物和聚合物共混物中拉伸粘度的研究。 该仪器促进的研究将允许更完整地表征广泛的材料类别，并导致开发具有特定拉伸性能的新材料。流变仪还将使当前和未来的学生能够研究拉伸性能，并调查这些性能对材料加工的影响。 被研究的材料的例子是高度缠结的聚合物溶液和熔体，聚合物共混物，复合材料和悬浮液。塑料和橡胶在挤压或拉伸时具有非凡的性能。 将它们分开涉及拉伸粘度等措施，这些措施在这些材料的机械性能中起着至关重要的作用。 该基金支持的仪器采购是为了帮助研究这些技术关键材料的机械性能。
