This Request for Proposals (the “RFP”) is an invitation by the University of Ottawa (the “University”) to prospective proponents to submit proposals for an Oxygen Transmission Rate Measurement and Water Vapour Transmission Rate Measurement Systems, funded by the Canada Foundation for Innovation and the Ontario Research Fund. Prospective proponents must be able to supply both systems.
THE DELIVERABLES
The proposed equipments are an Oxygen Transmission Rate Measurement System and a Water Vapour Transmission Rate Measurement System.
Oxygen Transmission Rate Measurement System:
Oxygen transmission rate (OTR) measurement is to quantify the rate at which oxygen permeates through target materials, typically thin polymeric film, containers, and membranes. This is a critical method in academics and industries such as textile, pharmaceuticals, nanocellulose, food, and health and safety-related wearable applications, maintaining object integrity and extending lifetime under a given environmental condition.
The requested equipment is an advanced Oxygen Transmission Rate (OTR) measurment system to support our research and development in functional thin film analysis. This equipment will enable us to accurately assess the oxygen permeability of various thin films, including polymer, nanocellulose, and ultrathin metallic films, providing critical analysis to understand the interface between multi-stack films in the then-nanometer range. Significantly, the center for Hybrid Interfaces and Intelligent Thin-Films (HIIT) is a partnership between academia and industry to bring transformational advances in hybrid thin films and devices and convergence with more established technologies such as bulk semiconductors. Both uOttawa and industrial partners will benefit from OTR measurement, where controlling oxygen permeation is critical to maintaining product integrity, ensuring that we can optimize and develop materials that provide ideal barrier properties against a given environmental condition. With growing environmental concerns, ORT measurement will help us establish eco-friendly packaging materials that balance required oxygen barrier performance with sustainability.
Water Vapour Transmission Rate Measurement System:
A water vapour transmission rate (WVTR) measurement system evaluates the rate at which water vapor permeates through a material, especially films or membranes, under temprature and humidity conditions. This measurement is essential for materials used in packaging, pharmaceuticals, and electronics, and moisure barrier properties are critical to maintaining the integrity and lifetime of devices.
The requested equipment is a precise water vapor transmission rate (WVTR) measurement. This system is for testing the permeability of materials to water vapour. WVTR measurement is critical for engineering fields, including electronics, packaging, and pharmaceuticals, where controlling moisture levels is essential for thin film quality, safety, and longevity. WVTR system will provide accurate, reliable, and repeatable testing results, ensuring that deposited films meet required standards and performance criteria, which is well aligned with the objectives of Center for Hybrid Interfaces and Intelligent Thin-Films (HIIT) objectives. Understanding the interactions between thin films of various hybrid materials, such as organic-inorganic, organic-metal, and high throughput, low-cost, and low-power consumption roll-to-roll (R2R) manufacturing approaches will offer Canada and the world revolutionary innovations in technology that will bring tremendous positive economic, health, social, and environmental impacts. Innovations include; (i) the realization of low-cost intelligent labels that detect water permeation through the film, (ii) biometric sensors integrated into textiles that can identify disease in human sweat for early detection and prevention, and more. Under this scope, measuring the water permeation through thin films, interfaces, and packaging is essential to HIIT research.
