Publication number: 20230251406Abstract: Dynamic mirror assemblies are disclosed that can vary the amount of light reflected, that include a mirror and a switching material. The switching material is placed between the mirror and a viewer, and has a dark state and a light state, and switches state in at least one direction due to a photochromic reaction, and switches in the other direction due to one or more of a photochromic reaction or an electrochromic reaction or a thermal reversion above a threshold temperature.Type: ApplicationFiled: July 13, 2021Publication date: August 10, 2023Applicant: SOLUTIA CANADA INC.Inventors: JONATHAN ROSS SARGENT, RYAN J. GIBSON, JEREMY GRAHAM FINDEN, NEIL ROBIN BRANDA, GREG STUART, JAMES DANIEL SENIOR, MATTHEW NEAL ROBERTS

Patent number: 11537021Abstract: A simplified switchable object and methods of making same are provided. The methods may include steps of applying a switchable material on a first surface of a first substrate, the switchable material having a thickness and a shape; applying a barrier material on the first substrate, circumferential to the switchable material; and applying a second substrate over top of, and in contact with, the switchable material and the barrier material, the first substrate, second substrate and barrier material defining a closed chamber encapsulating the switchable material. The methods may further include a step of applying a seal material.Type: GrantFiled: February 26, 2019Date of Patent: December 27, 2022Inventors: Simon James Gauthier, Duhane Lam, Jonathan Ross Sargent, James Daniel Senior, Cynthia Elizabeth Shippam, Peter Alexander Von Hahn

Publication number: 20220220100Abstract: A diarylethene compound reversibly convertible under photochromic and electrochromic conditions between a ring-open isomer of Formula (1A) and a ring-closed isomer of Formula (IB) wherein R5 is a substituted phenyl ring and Re is a substituted thiophene ring is provided. The photochromic-electrochromic diarylethene compound of Formula (1A)/(1B) have improved photochromic, electrochromic or photochromic and electrochromic properties, and is useful to provide variation of the light transmission properties of optical filters. The compound also possesses improved solubility making it suitable for incorporation in commercial products.Type: ApplicationFiled: April 2, 2020Publication date: July 14, 2022Applicant: SWITCH MATERIALS INC.Inventors: SHAO-KAI CHEN, RICHARD JOHN BURFORD, AMIR MAHMOUD ASADIRAD, TUOQI WU, JAMES DANIEL SENIOR, NATALIE ELAINE CAMPBELL, GLEN RAMSAY BREMNER, NEIL ROBIN BRANDA, JEREMY GRAHAM FINDEN
