Thermoplastic Polyurethane Electrolyte Development for eWindows

Miru Smart Technologies (Miru) is developing the next generation of low-cost, energy-efficient, high-quality eWindows for residential, commercial, and automotive industries. Using scalable and adaptable methodologies, electrochromic windows have the potential to yield significant gains in energy efficiency by offsetting user climate control requirements while simultaneously providing a high-quality consumer experience.
In Q1 2025, Miru recently announced its partnership with US-based firm Mativ, a global leader in thermoplastic polyurethane interlayer production. The Miru-Mativ partnership has so far focused on co-development of a polymeric electrolyte for Miru’s eWindow technology, satisfying unique constraints related to electrochemical durability, mechanical durability, and a range of standard glazing optical requirements. While substantial progress has been made in this area, fundamental electrochemistry and polymer chemistry must be further developed to enhance durability and product performance.
The proposed project herein aims to centralize new iterative chemical formulation development processes for polymer electrolytes in Miru’s Vancouver-based Technology Centre at 68 E 1 Avenue. In order to meet durability targets, and to provide needed feedback for external industry partners, a wide range of materials and method development will be required to inform strategic product development goals in Miru’s next generation product.
