This proposal requests a robust and all-encompassing Advance In Situ Visualization System (AIVS), developed by Linkam Scientific Company (Linkam), which is capable of simultaneously monitoring the microstructure evolution of polymeric and hybrid composites, with precise temperature and humidity control, as well as capabilities for applying controlled shear, extensional deformations, and thermal treatment onto the polymer composite, in both melt- and solid-states. Unlike other conventional melt- and solid-state characterization techniques (such as, Shear/Extensional Rheology, Tensile/Compressive/Flexural Mechanical Testing, and Differential-Scanning Calorimetry), this system allows for the direct visualization of the microstructure evolution under each type of perturbation. Linkam's AIVS facilitates a direct understanding of how deformations applied during processing impact microstructure topology, and how this microstructure affects the thermomechanical behavior of composites. Specifically, this is one of the world's most innovative multifunctional polymer characterization equipment, allowing for high resolution optical measurements of structures on the scale of single-microns with a wide range of humidity and temperature control. Currently, no such comprehensive microstructure visualization system under controlled stresses and thermal treatment exists in Canada. Hence, Linkam's AIVS is of high value to the research, design, and optimization of engineered materials, as its capabilities will pave the way for new discoveries and novel advancements. The success of this application would bring a high sensitivity AIVS to the University of Toronto (U of T), making it the first of its kind in Canada, and at a crucial time. We are in the middle of a turbulent era of realization of the effects of climate change by the general population, with consumer demand rapidly shifting to eco-friendly and efficient products that reduce waste materials. Furthermore, investment in this equipment will help to facilitate Canada's growth as a world leader in advanced materials and manufacturing. Therefore, we are requesting $148,962.03 CAD to cover the cost to purchase Linkam's AIVS for the research programs targeting: (1) In Situ Fibrillated Polymer Composites, (2) Sustainable Polymer Nanocomposites, and (3) Nanolayered Polymer Films and Coatings. Overall, this equipment will be a vital asset supporting multiple HQP within the U of T's Departments of Mechanical and Industrial Engineering, Material Science and Engineering, and Chemical Engineering and Applied Chemistry, as well as the Faculty of Forestry. Ultimately, Linkam's AIVS will allow us to monitor and understand the microstructure evolution of polymer and hybrid composites, while simulating the shear and extensional deformations experienced during processing, making it critical to engineer materials with tailored properties to meet the demands of novel applications.
