POWRE: Determination and Modelling of Synergistic Effects of Carbon Based Conductive Fillers for Electrically and Thermally Conductive Resins

女性研究和教育专业机会(POWRE)项目旨在调查几种形式的碳基导电填料结合在一起以提高聚合物复合材料的导热和导电性的协同效应。目前商业上生产的导电和导热树脂数量有限。然而，由于对电子噪声的更严格监管，以及对更小、更密集封装的电子元件的需求增加，对导热和导电树脂的需求正在迅速增长。目前或过去研究的绝大多数导电树脂只使用一种类型的导电填料。在之前的工作中，主要研究人员已经注意到，当三种不同的碳基导电填料在尼龙6，6基质材料中组合时，会产生积极的协同效应。因此，在这项研究中，将使用析因设计方法来确定四种不同的商业上可获得且成本效益高的碳基导电填料对聚碳酸酯和尼龙6，6基导电树脂导热和导电性的影响。这些导电树脂将被进一步研究，以确定变量(组分的导电性、基质的结晶度%、复合材料中导电填料的长度、导电填料之间的距离等)。影响导热和导电性的物质。这些信息将被用于开发导热和导电性模型，以准确预测含有不同导电填料组合的导电树脂的导热和导电性。该项目预计将为首席调查员的学术追求提供联网机会，并扩大她早期专业活动中的产业联系。

This Professional Opportunities for Women in Research and Education (POWRE) project is to investigate the synergistic effects of combining several forms of carbon based conductive fillers to enhance the thermal and electrical conductivity of polymer composites. Electrically and thermally conductive resins are commercially produced today in limited quantities. However, demand for thermally and electrically conductive resins is rapidly growing due to more stringent regulation on electronic noise, as well as the increased need for smaller, more densely packed electronic components. The vast majority of the conductive resins available today or studied in the past utilize only one type of conductive filler. In prior work, the principal investigator has noted a positive synergistic effect when three different carbon-based conductive fillers are combined in nylon 6,6 matrix material. Hence, in this study, a factorial design approach will be used to determine the effect of four different commercially available and cost effective carbon-based conductive fillers on the thermal and electrical conductivity of a polycarbonate and a nylon 6,6 based conductive resin. These conductive resins will be further studied to determine the variables (conductivity of the constituents, % crystallinity of the matrix, length of conductive filler in the composite, distance between conductive fillers, etc.) that affect thermal and electrical conductivity. This information will be used to develop thermal and electrical conductivity models that accurately predict the thermal and electrical conductivity of conductive resins containing combinations of different conductive fillers. The project is expected to provide networking opportunities for the principal investigator in her academic pursuits, as well as to expand upon the industrial links from her earlier professional activities.
