The grant application entitled, "Investigation on Interfacial Interactions in Polymer Blends and Composites by Complimentary ATR-FTIR-AFM Imaging System" is requesting fund to obtain an attenuated total reflection-Fourier transform infrared (ATR-FTIR) imaging system - ALPHA FT-IR Spectrometer. The goal of this program is to provide a unique means to elucidate polymer-polymer, polymer-filler, and filler-filler interactions in polymer blends and polymer composites using complimentary analyses by the proposed ATR-FTIR and an existing atomic force microscope (AFM) in the Smart and Adaptive Polymer Lab. AFM is an exceedingly powerful and useful technique for characterizing the morphology, topology, and various multifunctional properties of heterogeneous material systems. However, there remains a fundamental challenge with AFM-based imaging because conclusions are inferred based on morphological or topographical features. It is conventionally very difficult to use AFM to confirm specific molecular conformation, especially in the case of polymer-polymer, polymer-filler, and filler-filler interactions. In this context, a research platform consists of both AFM and ATR-FTIR will provide direct correlations between structural and topographical features resolved by AFM with spectroscopic details of molecular structure and conformation in the aforementioned materials interactions. The understanding of these interactions is crucial in the development of novel multifunctional materials with tailored mechanical, electrical, and thermal properties for a wide spectrum of applications, ranging from daily commodities (e.g., electronic packaging and disposable cutlery) to advanced engineering applications (e.g., heat management for future chips with three-dimensional architectures and bioscaffold). Ultimately, the system will serve as the heart of experimental facilities to develop novel multifunctional and active polymer blends, composites, and specialty foams. It will also contribute to the research in novel materials and their fabrications, ultimately promoting the technology development and economy in various sectors in Canada.

该基金申请题目为“通过免费ATR-FTIR-AFM成像系统研究聚合物共混物和复合材料中的界面相互作用”，要求获得一个衰减全反射-傅里叶变换红外（ATR-FTIR）成像系统- ALPHA FT-IR光谱仪。该计划的目标是提供一种独特的手段来阐明聚合物-聚合物，聚合物-填料和填料-填料在聚合物共混物和聚合物复合材料中的相互作用，使用建议的ATR-FTIR和智能和自适应聚合物实验室中现有的原子力显微镜（AFM）进行免费分析。原子力显微镜是一种非常强大和有用的技术，用于表征非均匀材料系统的形态，拓扑结构和各种多功能特性。然而，基于AFM的成像仍然存在根本性的挑战，因为结论是基于形态或地形特征推断的。通常，使用AFM来确认特定的分子构象是非常困难的，特别是在聚合物-聚合物、聚合物-填料和填料-填料相互作用的情况下。在这种情况下，由AFM和ATR-FTIR组成的研究平台将提供AFM解析的结构和形貌特征与上述材料相互作用中分子结构和构象的光谱细节之间的直接相关性。理解这些相互作用对于开发具有定制的机械，电气和热性能的新型多功能材料至关重要，用于广泛的应用，从日常商品（例如，电子包装和一次性餐具）到高级工程应用（例如，用于具有三维结构和生物支架的未来芯片的热管理）。最终，该系统将作为实验设施的核心，以开发新型多功能和活性聚合物共混物，复合材料和特种泡沫。它还将有助于新材料及其制造的研究，最终促进加拿大各部门的技术发展和经济。
