MRI: Acquisition of Nanospider for Development of Next Generation of Polymeric Nanofibers

[126193]为了使聚合物纳米纤维得到更广泛的应用，深入了解纤维形成物理和纤维化学至关重要。使用纳米蜘蛛静电纺丝装置进行的研究将具有变动性，因为它将提供一些基本问题的答案，包括聚合物-溶剂相互作用，粘度和表面张力在纤维可纺性中的作用，电位梯度和收集器距离（与含有聚合物的针）的影响。这些答案对于提供创新的解决方案来克服在更广泛地使用该技术中存在的技术障碍至关重要。纳米蜘蛛与UMD已有的其他设备相结合，将推动马萨诸塞大学达特茅斯分校在材料开发和表征方面进入一个利基领域，这将吸引当地企业和大学来帮助他们的商业/学术需求。

1126193SenguptaIn order for polymeric nanofibers to be used more widely, a thorough understanding of fiber-formation physics and fiber chemistry is critical. The research conducted using the Nanospider electrospinning apparatus will be transformational because it will provide answers to some fundamental questions involving polymer-solvent interaction, role of viscosity and surface tension in fiber spinnability, effect of potential gradient and collector distance (from needle containing the polymer). These answers are critical to provide innovative solutions to overcome technical barriers that exist in more widespread use of this technology. The Nanospider, in concert with other equipment already available at UMD, will propel UMass Dartmouth toward a niche area in material development and characterization that will attract local businesses and universities to assist their business/academic needs.
