Abstract
An electrochromic device is achieved that exhibits the characteristics of impact-resistant safety glass by starting with a solid electrolyte sheet material and a peripheral sealant material sandwiched between substrates to heat and pressure such that the electrolyte bonds to the treated surfaces of the substrates with an adhesion of at least 1.8 kg/linear cm width causing the electrolyte to exhibit a tensile strength of at least 5 kg/cm2.
Claims7
An electrochromic laminate comprising the steps of:
- a. placing a solid electrolyte sheet on a first substrate;
- b. placing sealing material around said perimeter of said solid electrolyte sheet;
- c. covering the sheet with a second substrate that extends over the sealing material;
- and
- d. subjecting both the electrolyte sheet and the sealing material to simultaneously applied heat and pressure to adhere said solid electrolyte sheet with said first and said second substrate.
An electrochromic laminate as in 2 which reduces sound transmission at least 3 dB.
