Improving the Performance of Dynamic Colour-Changing Materials Using New Heat Dissipating Materials – Towards Building Smarter Cities
EF 2019-20 · 2020-03-20
Résumé
This project will help overcome one of the major limitations for applications that use colour-changing materials – their temperature dependency. Many research groups and companies have attempted to commercialize organic molecules that undergo reversible changes in colour for applications in dynamic windows, UV indicators and eye-wear. However, all attempts have been held back by the fact that the colour-changing materials function differently at different temperatures. Typically, they darken too much at low temperatures and barely darken at high temperatures. A method to regulate the local temperature would provide an opportunity to employ this technology for many important applications.
The project will attach several classes of photoresponsive, color-changing molecules to the surface of nanowires that act as efficient heat conductors. It is anticipated that these optically transparent nanosystems will allow the photoresponsive compounds to undergo their characteristic changes in colour when exposed to different types of light, while reducing their temperature dependency. The project will target colour-changing films and inks for eye-wear, windows and sunscreen indicators.

Description (French)
Le projet concourra à surmonter un des obstacles majeurs nuisant aux applications qui exploitent les matériaux changeant de couleur : la dépendance à la température. Beaucoup d’équipes de recherche et d’entreprises ont essayé de commercialiser des molécules organiques dont la couleur varie temporairement en fabriquant des fenêtres « dynamiques », des indicateurs du rayonnement UV ou des articles de lunetterie. Malheureusement, les résultats laissent à désirer, car les matériaux de ce genre fonctionnent différemment selon la température. Le plus souvent, ils s’opacifient trop à basse température et s’assombrissent peu quand le mercure monte. Réguler localement la température faciliterait l’usage de cette technologie dans maintes applications importantes. Le projet prévoit la fixation de plusieurs sortes de molécules dont la couleur varie sous l’effet de la lumière à la surface de nanofils conduisant bien la chaleur. Ces nanosystèmes transparents devraient laisser les composés photosensibles changer de couleur comme ils le font naturellement lorsqu’ils sont exposés à divers éclairages, tout en atténuant leur dépendance à la température. Le projet se concentrera sur les pellicules et les encres photosensibles pour la lunetterie, les fenêtres et les indicateurs des écrans solaires.
Expected Results
In the short term, anticipated outcomes will be strengthened collaborations across industry, academia, and government to support research excellence. In the medium term, anticipated outcomes will be the development of new and potentially disruptive technologies with collaborators.
Expected Results (French)
À court terme, les résultats prévus sont des collaborations renforcées dans l’ensemble de l’industrie, du milieu universitaire et du gouvernement afin d’appuyer l’excellence en recherche. À moyen terme, les résultats prévus sont le développement de technologies potentiellement perturbatrices avec des collaborateurs.

Program Name (French)
Programme de collaboration en science, en technologie et en innovation – Fonds d’idéation
Program Purpose
The Ideation Fund is intended to encourage, test and validate transformative research ideas generated by teams of NRC scientific personnel and external collaborators with complementary capabilities, acting as a demonstration phase for a continually-evolving suite of research and development (R&D) deliverables at the NRC. The fund supports exploratory research through two mechanisms: the New Beginnings Initiative and the Small Teams Initiative.
Program Purpose (French)
Le Fonds d’idéation vise à encourager, à mettre à l’essai et à valider les idées de recherche transformatrice des équipes scientifiques du CNRC et des collaborateurs externes dotés de capacités complémentaires. Il servira ainsi de plateforme de démonstration d’une série de produits livrables en matière de recherche-développement (R-D) en constante évolution au CNRC. Le Fonds appuie la recherche exploratoire au moyen de deux mécanismes : l’Initiative « Nouveaux débuts » et l’Initiative « Petites équipes ».
